The Research on Motion Reliability Simulation of Planar Linkage Mechanism

Taking planar pivot four-bar mechanism for example, the method motion reliability simulation on solving motion reliability of planar linkage mechanism is proposed in this paper. Under the circumstances that manufacturing errors and joint clearances are normal distribution, ADAMS is taken as the analysis platform and the parameterized model of planar linkage mechanism is established by it, then Monte Carlo theory is used to calculate in order that different random simulation model can be obtained. After cycle simulation, the data of simulation will be saved in text files so that it could be used for calculating the result of motion reliability. This method is applied to solving motion reliability of the opening/closing mechanism of the bottom door in the coal hopper, and the result is reasonable, thereby its effectiveness is proved successfully.
