The mechanical model analysis of the generation of steel wire tension is carried out, and the axial stress change of steel wire under different pressures, different speeds and different diameters is analyzed by finite element soft-ware. The results show that the axial stress of the steel wire has a nonlinear relationship with the speed of the steel wire, and with the increase of the speed of the steel wire, the axial stress of the steel wire first increases, reaches the peak, and then decreases and eventually tends to be stable; The axial stress of the steel wire is proportional to the hydraulic cylinder pressure and inversely proportional to the diameter of the wire.","PeriodicalId":30222,"journal":{"name":"Journal of Mechanical Engineering and Technology","volume":"331 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77143442","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 convolution neural network model based on improved YOLOX-S is proposed for metal surface defect image detection. The model changed the structure of the unit module and introduced the attention mechanism module based on the original YOLOX-S model, which optimized the model parameters and improved bounding box position regression loss function and confidence loss function, and then the image detection model of common defects on the metal surface was constructed and realized. The results showed that the loss of improved YOLOX-S model could converge faster, the model with bounding box position regression loss function and attention mechanism added, its mAP increased from 94.23% to 96.14%, and the accuracy improvement effect is the best, while only a small amount of reasoning time is increased. Compared with the YOLOX-S model and the model with different improved methods, it is shown that the improved model based on bounding box position regression loss function and attention mechanism has the best comprehensive recognition effect, which can meet the require-ments of metal surface defect image detection and reduce the outflow of defective products in the production process of metal parts.","PeriodicalId":30222,"journal":{"name":"Journal of Mechanical Engineering and Technology","volume":"193 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77299476","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}
