Dynamics Simulation of Shaper Mechanism Based on MATLAB/SimMechanics

The basic functions of MATLAB/SimMechanics software were introduced.The model for dynamics simulation of shaper mechanism was setup in consideration of friction,and the three dimensional solid model of the shaper mechanism was established using Pro/E software.Moreover,the parameters were provided for simulation model through detecting the quality of components,the moment of inertia,and the location of the center of gravity with the help of measuring module.The simulation curve of reaction forces and equilibrium moment in each kinematic pair were obtained.The method does not need deriving complicated mathematical models,with the characteristics of fabulous visualization,simplicity and easy learning.
