The load-bearing structure of the snubbing operation device plays the main role of load-bearing, which is a necessary structure to ensure the safe and efficient completion of workover operations. and completion operations. The load-bearing requirements of the 340K snubbing operation device are greater. The finite element analysis process of load-bearing involves structural nonlinearity and boundary nonlinearity; the analysis model involves a variety of structure units, which increases the difficulty of the finite element analysis of the load-bearing machine of the full-scale structure. This paper establishes a full-scale finite element analysis model of the main load-bearing structure of the 340K snubbing operation device, analyzes the mechanical properties of the main load-bearing structure under main loads such as the weight, external load, and wind load (expected wind load and unexpected wind load), and analyzes the reaction force of the main loadbearing rope under load (working state, unexpected wind state, expected wind state);The main rope of the 340K snubbing operation device is subjected to a force test under wind load, and the force on the rope is measured. The analysis found that the maximum stress of the main body of the snubbing operation device under the working load is 155MPa, and the safety factor is 1.35, which achieves the conditions for safe work; the force of the rope obtained by the test is less than the rated tension of the rope 220KN, which achieves requirements of various working conditions. Through the calculation and analysis under the load of the snubbing operation device, it provides an important basis for ensuring the safe operation of the snubbing operation device.","PeriodicalId":219763,"journal":{"name":"2021 International Conference on Electronics, Circuits and Information Engineering (ECIE)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115624842","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}

It has some unique advantages over thermal ablations, including no sensitive to the ‘heat-sink’ effect of blood vessels and preserving surrounding vital structures. However, there is still a risk of cancer recurrence with IRE, especially with heterogeneous tissues. For heterogeneous tissues, the existence of structures with different conductivities makes it difficult to control the ablation outcomes of IRE. In this study, we used finite element simulation combined with experiments to observe the influence of heterogeneous implants on the shape of the ablation zone in a plant model. Electrochemical impedance spectroscopy was used to extract the impedance data and characterize the relationship between relevant electrical parameters and ablation area. We found that the pulsed electric field would be distorted by the heterogeneous implant with high electrical conductivity, resulting in the irregular shape of the ablation zone, and the relative change value of the extracellular fluid equivalent resistance extracted from impedance spectrum was linearly related to the ablation zone. In conclusion, the ablation zone could be predicted by the proposed method in the study with an acceptable accuracy.","PeriodicalId":219763,"journal":{"name":"2021 International Conference on Electronics, Circuits and Information Engineering (ECIE)","volume":"140 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123347014","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}

Based on the principle of total reflection method, an experimental apparatus for dynamic observation of interface contact behavior is built for studying the evolution of contact state of transparent solid materials during stick slip motion. The displacement difference between the front- end and back-end of the slider in the contact pair stick-slip experiment is analyzed. The evolution of real contact area during stick-slip process is captured by the camera. It is found that in the stick stage, the center area with the largest contact strength in the contact area of interface asperity hardly moved. The displacement difference is mainly caused by the compression deformation of the slider and the micro slip in the local contact area. Based on the evolution rule of real contact area, the analytical model of massdamping-spring model considering stick-slip friction is established. The main contact parameters are determined by experimental identification, and the governing equation of the model is solved by the central difference method. Finally, the numerical results are compared with the experimental results to verify the effectiveness of the model. The model can qualitatively reflect the phenomenon of the displacement difference between the front-end and back-end of slider in stick-slip.","PeriodicalId":219763,"journal":{"name":"2021 International Conference on Electronics, Circuits and Information Engineering (ECIE)","volume":"150 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134174408","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 algorithm is more complex, and the reaction time is longer. Through the analysis and comparison of image RGB model, YUV model and gray processing, when segmenting video sequence image, transforming RGB color image into gray image is conducive to image recognition. When the scene background is complex, the image can be analyzed in the normalized RGB color space, which can effectively eliminate the influence of shadow. The filtering denoising of Gaussian low-pass filter and median filter are analyzed, which have good denoising effect. It is very suitable for image preprocessing and denoising after recognition. Through the analysis of morphology operation such as corrosion and expansion, the cavity problem can be effectively improved. Before the target detection, preprocessing the target video sequence by computer graphics method can highlight the useful image characteristics and remove the useless image information, which can help to improve the detection effect.","PeriodicalId":219763,"journal":{"name":"2021 International Conference on Electronics, Circuits and Information Engineering (ECIE)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129219856","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}
