So first the deep residual shrinkage network is pre-trained on the big data simulation dataset. And then to avoid imbalances between real data sets, GAN network is adopted to generate more datasets in this paper. Based on the aforementioned data set, the pretrained network is proposed to denoise the environment and other noise in the data set. And Spatial Dropout layer into the network is introduced to improve the accuracy and convergence speed of fault diagnosis. Experiments show that by combining GAN and DRSN methods for fault diagnosis of unbalanced samples, disturbances such as datasets and reducing environmental noise can be effectively balanced.

It is one of the important directions for the development of China’s building structure, of which prestressed concrete structure is an important part of the prefabricated concrete structure.

The tensioning process includes: 1 The prestressed steel strand penetrates the tension hole of the tensioning equipment. 2 the tensioning equipment continues to tension the prestressed steel strand. Among them, the perforation process of tension has always been manually realized. At present, industrial intelligence includes all walks of life, and equipment related to construction projects also conform to the development of intelligence. The intelligent tensioning robot proposed in this paper is based on the tensile equipment to add a robotic arm, sensors, etc., which can automatically find tensioning holes to facilitate the perforation process when the prestressed ribs are stretched, with the purpose of improving the efficiency of perforation, improving the safety of the tensioning process, and reducing the dependence of tensile construction on labor.

The exoskeleton is a highly human-robot coupled system with a complex dynamic model and working environment, so it is crucial that the controller works in concert with the user intention without relying on imprecise models. This paper proposes a motion controller for a lower limb exoskeleton, aiming to perform collaborative squatting assistance with efficiency and flexibility. This control strategy is designed for our exoskeleton which is equipped with a force sensor on the back. The high-level control is a force-velocity admittance model estimating the human intention by the interaction force, and the low-level control is based on PD closed-loop velocity control with gravity compensation. Through experimental studies conducted with our exoskeleton, the feasibility and effectiveness of the control strategy are demonstrated.","PeriodicalId":120073,"journal":{"name":"2022 IEEE International Conference on Mechatronics and Automation (ICMA)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124023181","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}

Therefore, it is necessary to study the degradation of mechanical properties during material fatigue. When the ultrasonic wave propagates in the metal component, it interacts with the fatigue damage in the material, so that the ultrasonic waveform is distorted and high-order harmonic components are generated, which can be used to characterize the degree of material fatigue and mechanical property degradation. This paper takes YL12 aluminum alloy and 45 steel as the research objects, and uses the COMSOL software to simulate the propagation process of the surface wave in the sample. The specimen is cyclically loaded by a tensile machine, an ultrasonic nonlinear detection platform is built, excitation pulse signal, analyze frequency domain waveform, and the second-order relative nonlinearity of the specimen under different cyclic loading times is calculated.
