Contact force is a complicated force in practical problem. By using the powerful function of ADAMS in dynamics analysis, we can solve it in a comparatively accurate way. Since a number of parameters are involved in the simulation in ADAMS, the initialization of them has a great influence on the simulation. Aiming at the contact force between wheels of wheel chair and ground, the value of the parameters was calculated and analyzed in this paper. The main research object in this paper is the parameter of the ADAMS/Solver. The result of the dynamics simulation is also used to test whether the parameters are defined properly or not. With this method, we find a better way to define the parameters in ADAMS.

The dynamics performance for lifting mechanism is a very important factor that affects its rapidity and stability. This paper gives the dynamics equations for lifting process by using a equivalent dynamics model, and makes dynamics analysis for cylinder forward push lever lifting mechanism in a condition of giving its movement rules, and then acquires curves of changing loads on key joints and acceleration of the load centroid by dynamics simulation using ADAMS for five movement rules. In the end, a better selection is made by contrasting the results. This would give some reference to improving the dynamical performance of the lifting mechanism.

The joint clearance on mechanism dynamic characteristics influence can not be ignored. This paper established a geometrical model of planar four-bar mechanism, it built the model of contact force and friction and embedded into the software of ADAMS dynamics analysis mechanical system, which analysis the dynamics simulation of mechanism. We obtain a accurate prediction of dynamic characteristics of mechanism with joint clearance effect from the analysis. What's more the results provide reference and basis for later mechanism design [1,2,3].

Robot Modeling

In order to improve the modeling efficiency of the industrial robot dynamics control, the recursive dynamics is studied based on the Spatial Operator Algebra (SOA) theory, and the procedure realization is built in the environment of Matahematica6.0 software. The high effective recursive forward and reward dynamics for the SOA theory, has a simple math expression and a clear physical meaning. The software structure of the forward and inverse dynamics is built and the industrial robot dynamics simulation model is realized based on the integrated procedure VB.NET and Mathematica 6.0. According to the analysis, the example of PUMA560 robot forward and inverse dynamics is studied, and correctness and validity is verified by computed examples.
