At present, various methods used to monitor the operation condition and analyze faults have their own traits and shortcomings. To realize the heavy duty gearbox’s operation condition monitoring and fault analysis, acoustic digital twin technology was proposed. Using noncontact far field acoustic signals, the operation condition can be monitored and faults can be analyzed. This new technology was characterized by locating and analyzing faults accurately. To improve the accuracy of the digital twin model, the contact stiffness model of the joint surface was further deduced. Finally, the frequency responses of sound pressure under different faults were compared and analyzed. It was shown that the proposed acoustic digital twin technology can be used to monitor the heavy-duty gearbox’s operation condition and analyze faults. Also, the results showed that this technology was feasible and accurate.","PeriodicalId":286146,"journal":{"name":"2023 14th International Conference on Mechanical and Intelligent Manufacturing Technologies (ICMIMT)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125313248","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 the anisotropic characteristics of the Fused Filament Fabrication (FFF) process, material models with bulk properties for Finite-Element-Analysis (FEA) lack accuracy. This problem was addressed in this research by tension (DIN ISO 527) and compression (DIN ISO 604) tests of polypropylene and elastic polypropylene filament for FFF in 0° and 90° printing directions. Furthermore, a recycling cycle for both filaments was carried out and reassessed. Based on the test results a transversely isotropic material model with bilinear hardening was generated and validated for the standard polypropylene filament with a three-point bending test (DIN ISO 178). The material model was capable of reasonably simulating the component behavior for the complex load scenarios up to a strain of 15 %. The combination of a cost, time and resource-saving simulation approach with a circular material strategy proposes a way for fusing performance and sustainability in the field of Additive Manufacturing (AM). The combination of recycling processes and material models, both assessed and verified experimentally, respectively, will help adapt the product geometry to the material properties modified from recycling.","PeriodicalId":286146,"journal":{"name":"2023 14th International Conference on Mechanical and Intelligent Manufacturing Technologies (ICMIMT)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130693047","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 experimental results showed that measure of grayscale balance and measure of horizontal color balance were positively significantly correlated with subjective balance. Measure of proportion of layer objects to interface frame was significantly positively correlated with subjective proportionality, while measure of proportion of layer objects to interface layout was negatively correlated.

Each sample will be equipped with different designs of Roof Spoilers and then subjected to a Computational Fluid Analysis (CFD) using ANSYS Fluent. The parameters used for evaluation are the drag coefficient two and its force counterpart. The results from the assessment will be compared between the non-equipped (Base version) and the models equipped with roof spoiler model (RSM). The results show that RSM’s curvature would perform better than the planar version. The significant improvement of curvature RSM ranges from about five to twenty percent, while planar RSM ranges from up to fifteen percent, varying from different trucks. L300 WT has the lowest improvement, with a peak of eleven percent, followed by H100, with a peak of thirteen percent. The K2500 has the highest peak of improvement, gaining up to twenty percent.
