Dynamic Performance Indices Analysis for One-loop Planar Mechanism on

摘要

Acceleration global performance index based on Jacobian and Hessian matrices for one-loop planar mechanism is proposed. Using acceleration global performance index, acceleration performance of crank rocker mechanism is analyzed and atlas of dynamics performance indices is given. By using the result of atlas, mechanism with better acceleration is found. At last, the crank rocker mechanism is simulated by Matlab software, and simulating atlas of acceleration is given, the results are completely consistent with the results of theoretical analysis, which validates the correctness of theoretical analysis and the feasibility of performance index.
