Design And Research Of Squeezing And Reversing Composite Elastic Rubber Coupling

With the rapid development of China’s machinery, ships, vehicles, petroleum,chemical industry, water conservancy and defense weapons engineering, relatedmachinery and equipment in power transmission system is put forward more stringentrequirements in efficient environmental, protection high reliability and long service life,etc. In a way, the reliability of the coupling directly affects the transmission of functionand life.This article research is based on Professor Wang’s research and develop object"squeezing and reversing composite elastic rubber coupling". The aim of this paperthrough the analysis of the dynamic characteristics of the high elastic rubber coupling,periodic impact loads damping buffer mechanism, highly elastic rubber nonlinearconstitutive model, highly elastic rubber physical, chemical and mechanical propertiesof materials, and squeezing and reversing composite elastic rubber coupling to optimizethe design, is to provide theoretical references for the implementation ofhigh-performance, high-reliability research and development of the transmissionmechanism. The main contents are as follows:①By studying the simplified mechanical model of elastic coupling, elasticcoupling of torsional vibration differential equation is established, and by solving thedifferential equation, the elastic coupling relative angle displacement was gotten;Further to the elastic coupling under periodic load mechanism of vibration reductionwas discussed in theory. Based on the above theory, and by studying the workingprinciple, structure characteristics, rubber and metal bonding technology of squeezingreverse composite elastic coupling, we put forward extrusion reverse composite elasticcoupling of innovative design ideas, and through the Solidworks3d software foroptimization design and modeling.②For the key components of rubber elastomer of extrusion torsion complexelastic coupling, physico-chemical and mechanical performance experiment study,including rubber formula design, the choice of vulcanizing agent and reinforcing agent,mixing experiment, vulcanization and the stretch mechanics performance were carriedout, which reveals that the mechanical properties of rubber modified mechanism, andprovide basic data for the finite element analysis for the follow-up.③Using the finite element software（ABAQUS） to extrusion torsion complex elastic coupling nonlinear dynamics simulation analysis, based on the analysis ofcoupling in the rated torque under the action of the dynamic characteristics, includingthe stress and deformation, torsional rigidity and the size of the contact stress and thevariation characteristics, which provided a theoretical basis for the high elastic couplingdesign and the research.④Based on two kinds of advantages and disadvantages of modal analysis methodThrough analysis research method analysis and modal analysis theory and itsadvantages and disadvantages, freedom of the finite element modal and experimentalmodal analysis were established. The natural frequency and vibration mode of thecoupling were obtained. The results of the analysis for follow-up, noise and structuralvibration control experiments provide a theoretical basis.
