These are extremely complex systems that characteristically demand expensive maintenance programs, due to the high costs involved in an eventual shutdown. Consequently, critical faults diagnosis and prognosis are essential in the operation condition of those systems. Fault identification and classification criticality demand a robust verification of the codes and calculations, as well as a discerning validation of the numerical models used for rotating machinery. Hence, verification and validation (V&V) are an essential initial service for a digital twin (DT) so it may offer some advantages in this application. In this context, the following research question is proposed: Does V&V using DT improve data access and reduce the effort of data exchange? The following objectives are created to address the research question: perform a code verification, conduct the calculation verification, validate the models using two different validation approaches 1 and 2, and demonstrate easy access to asset data. For this study, two hydrodynamic bearings and a non-central disk were considered, representing a laboratory experimental setup. The validation metric requirement is promisingly satisfied for the disk and the bearings according to the validation approaches 1 and 2. Furthermore, validation approach 2 generates even more successful results than approach 1. Accurate estimation and reliable interpretation of the numerical model outcomes guarantee the DT application for future fault diagnosis and prognosis.","PeriodicalId":44694,"journal":{"name":"ASCE-ASME Journal of Risk and Uncertainty in Engineering Systems Part B-Mechanical Engineering","volume":"103 5","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136133048","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A human comfort evaluation function based on force analysis was proposed to improve the comfort of a dual-arm transfer robot. First, a human-robot mechanical model was construct by simplifying the structure of human body and the robot. Then, the internal and external forces acting on human body were calculated by the developed human-robot mechanical model. After that, a comfort evaluation function was established through mechanical analysis and a questionnaire investigation method. To assess the validity of the proposed method, first we employed the comfort evaluation function to estimate human comfort, and obtained that the comfort level is proportional to the EMG signal and pressure signal of human. Then we applied the function to a dual-arm patient-transfer robot to optimizing lifting points and transfer posture and found it can effectively reduce the human-robot contact force and the burden of the waist by 44.2%, improving the comfortability of the care receiver.","PeriodicalId":44694,"journal":{"name":"ASCE-ASME Journal of Risk and Uncertainty in Engineering Systems Part B-Mechanical Engineering","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135883294","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The procedure uses vibration measurements to extract features and to train a classifier using a Gaussian Mixture Model (GMM). The key to enhancing the surrogate model for torque loss detection is considering the bolted joint structures with more qualitative and quantitative knowledge as the source domain, where labels are known and the classifier is trained. After applying a domain adaptation method, it is possible to reuse this trained classifier for a target domain, i.e., a set of different limited data of bolted joint structures with unknown labels. Four different bolted joint structures are analyzed. The new experimental tests adopt a wide range of torque in the bolts to extract the features with the respective labels under safe or unsafe tightening torque. All combinations of possible source or target domains are considered in the application to demonstrate whether the method can aid the detection of the loss of tightening torque, reducing the learning steps and the training sample. A guidance list is discussed based on this population-based SHM of bolted joint structures.","PeriodicalId":44694,"journal":{"name":"ASCE-ASME Journal of Risk and Uncertainty in Engineering Systems Part B-Mechanical Engineering","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135883245","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to this context, the use of digital twins and digital shadows, which are virtual representations of physical systems that provide real-time monitoring and analysis of the health and performance of the system, have been increasingly used in the application of fault detection, a key component of PHM. Taking that into consideration, this work proposes a framework for fault detection in engineering systems based on the construction and application of a digital shadow. This digital shadow is based on a digital model composed of a system of equations and a continuous, real-time communication process with a Supervisory Control and Data Acquisition (SCADA) system. The digital model is generated using monitoring data from the system under study. The proposed method was applied in two case studies, one based on synthetic data and another that uses a simulated database of an operational generating unit of a hydroelectric power plant. The method, in both case studies, was able to detect faults accurately and effectively. Besides, the method provides by-products that can be used in the future in other applications, helping with the PHM in other aspects.","PeriodicalId":44694,"journal":{"name":"ASCE-ASME Journal of Risk and Uncertainty in Engineering Systems Part B-Mechanical Engineering","volume":"214 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135882949","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, analytical calculation and Monte Carlo Simulation (MCS) are not feasible for approximating the survival signature of large infrastructures, because of the complexity and computational demand due to the large number of components. In this case, efficient and accurate approximations are sought. In this paper we formulate the survival signature approximation problem as a missing data problem. An ensemble of artificial neural networks (ANNs) is trained on a set of survival signatures obtained by MCS. The ensemble of trained ANNs is, then, used to retrieve the missing values of the survival signature. A numerical example is worked out and recommendations are given to design the ensemble of ANNs for large-scale, real-world infrastructures.

These perturbations, such as natural hazards, can highly affect the networks' resilience. Increasing the ability of metrorail networks to withstand such perturbations requires robustness and vulnerability assessments as key attributes of resilience and necessary steps toward developing reliable networks. Most models developed for this purpose associate a network's failures to binary representations of the failure of its components without incorporating weight factors. Since ridership is a primary factor to define the metrorail network performance, this paper proposes a general ridership pattern, considers different failure cases, and uses a novel methodology to quantitatively measure the weighted-network resilience attributes incorporating ridership throughout the Washington, DC Metrorail as a case study. The proposed methodology has clear relationships to adjacency and link-weight matrices and defines a new expression for the weighted global network efficiency based on the sum of weights on each geodesic path. Results show that the most vulnerable stations and links hold critical positions in the network topological structure and/or bear larger amounts of ridership. For the case study, the most vulnerable components include transfer stations located in the city center as well as stations and links on the northwest section of the Red Line. The methodology presented herein provides insights for enhancing critical components during the planning and operation of a metrorail by mitigating the risks associated with failure events.","PeriodicalId":44694,"journal":{"name":"ASCE-ASME Journal of Risk and Uncertainty in Engineering Systems Part B-Mechanical Engineering","volume":"88 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135647972","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One of the possible solutions being studied is the implementation of Power Hubs, which would generate electricity and distribute it to nearby platforms. Unlike the traditional approach, in which the electricity is generated in the platform for its operation, centralizing such generation via Power Hubs can make the process more efficient, reducing CO2 emissions. However, such a configuration increases the complexity of the operation and can impact the reliability and availability of platforms connected to the Power Hub. Therefore, this work aims to perform reliability and availability estimates of this type of operational configuration and compare it with the traditional offshore operation to quantify the difference between them. Various kinds of Power Hubs configurations were also analyzed to compare the results obtained. Such analyzes were performed using Generalized Stochastic Petri Nets (GSPN) models. Results show that, depending on their configurations, Power Hubs can guarantee an average availability of energy generation close to 100% even in periods of higher demand for oil and gas production.","PeriodicalId":44694,"journal":{"name":"ASCE-ASME Journal of Risk and Uncertainty in Engineering Systems Part B-Mechanical Engineering","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135826432","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
