【Abstract】 Virtual prototype design of the novel 3-PRRPu parallel robot is realized by using of the top-down method,generalized modular design and parametric design.Design program is completed in terms of the top-down method based on Pro/E layout and skeleton model.The generalized modules of the prototype are divided and modular interfaces are designed on the basis of parallel mechanism structure characteristics.The interchangeable synthesis of the modules is performed by using Pro/E software.A new approach to create layout is presented by using of the three-dimensional drawing function of Pro/E and the two-dimensional drawing function of AUTOCAD software.The forward and the inverse kinematics simulations of the virtual prototype are carried out by means of Pro/E software.In addition,the dynamics analysis and simulation are discussed based on the ADAMS software.更多还原
