Research On Optimization Analysis And Damage Identification Of Axis Virtual Prototype

Through in-depth study of the optimization analysis of virtual prototyping and the damage identification of simple shaft rod,the design of shaft rod parts is optimized,the service life of shaft rod parts is increased,and the reliable working time is prolonged.The possible damage is predicted.This paper deeply analyzes the shaft mechanism in the internal combustion engine.The shaft mechanism is a core of the internal combustion engine,and the modeling and simulation analysis is performed by using ADAMS software.Study the extremes of various parameters between the various components in the operation of the project,and the impact on the shaft.The crank drive torque and the extreme values over time are analyzed.The influence of the change of the reaction force between the crank and the connecting rod on the damage of the shaft parts is analyzed.At the same time,the influence of the shaft mechanism under different crank lengths is studied,and the optimal working condition is established.This paper starts from a relatively simple shaft system,and analyzes and deduces the influence of time domain signal on it during vibration.Firstly,the vibration experimental test model of the shaft structure is proposed.In this structure,starting from the basic dynamic vibration theory,the elastic modulus of each part of the shaft or the time domain signal of the crack damage test at the same node is derived.relationship.The crack detection of the shaft is performed using the correlation matrix derived from the paper.The defective part of the shaft is regarded as the loss of the elastic modulus of the shaft.Finally,the simulation of ABAQUS and MATLAB shows that the method canbetter identify the number and location of defects in the simulation,and can be used as a supplement to the existing defect detection methods.
