In the engineering field, many motion's tracks are too complicated to be described in mathematical expression accurately, and solving this problem by using ADAMS. In this paper, parameters analysis and data processing were discussed based on the analysis of simulation animation and measured curve according to the characteristics of the model, to ensure the(More)
It's an important method to improve the mechanical properties of forging by studying variation of the crystal grain and realizing the quantitative prediction of the forging process. The inner grain evolutionary model during stretching of shaft heavy forging was established by the microstructure project module based on the cellular automata method of(More)
Three degrees of freedom (TDOF) vibration system during sheet blanking based on servo press is established, and the amplitude vibration of the body, slider and base of the servo press is simulated by the software Matlab/Simulink. The influence of the blanking speed and the initiation fracture position of blank on the maximum amplitude of slider are analyzed(More)
The automotive installation soleplate part researched in this paper is made by the high strength steel. It has a very complex shape and is difficult to be deformed. The forming processes of the installation soleplate part include blanking, deep drawing, local forming and bending, etc. To obtain the reasonable strip layout design and the multi-position(More)
The roller feed track during spinning of hollow part with straight edge triangle cross-section was researched. The variation characteristic of the contact point between the roller and workpiece was obtained: the contact point moves not only along the axial direction caused by the roller axial feed, but also along the radial, circumferential and axial(More)
