Workspace Analysis and Simulation of 3-PCR Parallel Mechanism

Inverse position equations of 3-PCR parallel mechanism were obtained by coordinate conversion method, based on the influence factors to the workspace of parallel mechanism, workspace volume under a certain size was worked out with method of polar coordinates boundary searching. According to mathematical model, using MATLAB software, solid figure and cross-section diagram of the mechanism in a certain range of size were presented. Finally, characteristics of workspace were analyzed through diagrams. Workspace analysis can provide necessary preconditions for the design and manufacture of parallel mechanism.
