| Abstract: | Based on the geometrical theory of the reliability index and the improved PSO,a new kinematics accuracy reliability method of the mould-cut main mechanism is presented.The proposed method avoids the solution for the mean value and the standard deviation of kinematics error of Main-cut mechanism,and for the first order or more partial derivatives of the performance function.Simulations results on kinematics accuracy reliability of mechanism demonstrate that the proposed method is accurate,practical and effec... |
