Abstract
To simplify the inverse kinematics model of special five-bar mechanism based on Assur group, a inverse kinematics model is proposed by using vector analysis method and Euler’s formula, which is expressed by all explicit equations and establishes a direct relation between the output motion and the input motion. A numerical example and a computer simulation were conducted to verify the mathematical model. Results show that the motion law of control bar l4 obtained directly from the mathematical model is consistent with the result from ADAMS simulation, and the mathematical model of the special five-bar mechanism is correct and can be used to analyze the motion law of the drive bar and the control bar directly according to the motion parameters of the output point.
