The mathematical error model of 3-TPT parallel platform is established by using matrix method. Based on the method, the influences of the length errors of legs and the position errors of joints on the end errors of moving platform are analyzed by using Monte-Carlo simulation, thus offering theoretical guide to compensating the errors of PMTs. This method is straightforward and easy to program. Numerical examples of error analysis are given for illustration. The results indicate that the errors of work platform are quite small, which can achieve kinematical accuracy.
