Research on Dynamic Assembly and Kinematics Simulation of Speed Reducer Based on Three-Dimensional Model

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.

The three-dimensional model of a Half Toroidal Continuously Variable Transmission (HT-CVT) was established by CAXA solid design. The kinematics simulation of the HT-CVT was realized by replacing the traction drive of elasto-hydrodynamic lubrication (EHL) oil film with the contact constraint joints in ADAMS. The angular velocity curves of the power rollers and the output cone disk on the HT-CVT were obtained. Simulation results demonstrate the fluctuation of the angular velocities on the two power rollers and the output cone disk compares well with the conclusion derived from the actual gear ratio of the HT-CVT.

To solve the instability of track robot in the process of climbing obstacles, a track robot with passive rocker was designed and a three-dimensional model of track robot was developed by Unigraphics NX in this paper. Furthermore, the kinematic analysis was made for obstacle performance of the track robot. The virtual prototype model of the track robot with passive rocker was set up by using the tracked vehicle subsystem of multi-body dynamics simulation software RecurDyn and kinematics simulation for this robot was made. The simulation results verify the feasibility of the machine and provide some theoretical guidance for developing the obstacle performance of track robot.
