Based on the characteristics and the common massage manipulations of Chinese medical massage, a practical series mechanical arm was presented to act the manipulations with the parallel executive mechanism. Forward kinematics was solved by the Denavit-Hartenberg transformation after the kinematics model of the arm was established. And the three-dimensional model of the arm was created by Pro/E and was imported into ADAMS for the kinematics analysis. The results indicated that the common massage manipulations could be simulated by the arm correctly and flexibly, and it verified the accuracy of the mechanism design of the arm.

Lapping Machine

The V-groove angle of the machine is considered as one of important factors affecting the processing and the ball’s precision. To study its effect, the three-dimensional model of RDP lapping machine is built and a series of simulations at different V-groove angles are carried out, using the software ADAMS based on the RDP principle. The influence of three parameters including spin angle, spin angular velocity and revolution angular velocity are discussed by observing and analyzing the simulation results. It is concluded that some optimized V-groove angles can improve the sphericity of ball; some ones can induce the balls to move back and roll during some periods of the processing.
