Abstract: the automobile constant velocity universal joint driving shaft is the important component in modern cars, its design is mainly to check the movement compatibility of parts. The constant velocity universal joints driving shaft is designed by three-dimensional solid modeling software UG, and the motion simulation model is build by multi-body dynamics simulation software to investigate the constant speed performance of constant velocity universal joints driving shaft, and check the motion trace of steel ball which is the key component of constant velocity universal joints. The results show that the constant speed performance is good, and the track design of star-like inner race is reasonable.

Abstract: Hydraulic support is important supporting equipment in fully mechanized coal mining. Its working performance and efficiency have relatively big effect for the efficiency of coal mining. Aiming at the characteristics of dynamic requirements, parametric design and simulation analysis of the hydraulic support, a multi-body kinetics based hydraulic support intelligent simulation design and analysis method is proposed. The three dimensional model of the support is set up with Solidworks, and then the 3D modeling is converted to ADAMS software for motion simulation. Some key components in the model are imported to ANSYS software to perform the finite element analysis to acquiring the optimized design variables.

Abstract: This paper aims to study the system of the compliant control for the polishing robot .Based on the mechanics model and dynamics equation that is established of the robot, the mechanical characteristics of the end of the grinding is analyzed. At the same time, the simulation of the movement for the robot is carried on by the ADAMS. By applying the constant load and the functional load on the polishing end, the force and torque diagram for each of the robot arm joint are obtained. At last, the conclusion that the force and the torque of the first joint is the largest can be obtained and the force of joint can keep the good constancy.

Abstract: This paper presents a parametric design method of the cam profile curve with UG NX, created the cam curves with law of the curve command, conducted curve continuity analysis with Curve Continuity Analysis command, and the results show that all adjacent curves are tangent continuous. This ensures the design accuracy. The velocity curve and the displacement curve were got through the cam motion simulation, and the motion analysis is consistent with the results of theoretical design. Expressions were changed, and the motion analysis show that the parametric design of the cam contour is reasonable.

The structure and function of grass burying rotary tilling blade roller was elaborated in the paper. This paper mainly did simulation analysis about the motion track of grass burying rotary tilling blade roller. The results showed that the forward speed of the machine had significant influence on the motion track of blade roller while at the certain rotational speed and gyration radius.

Abstract: Due to the high flow pulsation，the ordinary gear pump has large vibration, noise. A new structure named multi-gear pump was proposed. The model of the pump was established. The motion simulation was given to compare with common gear pump. The simulation analysis show that the pump tooth contact force pulse value is 0.296, which is about 25% lower than the common gear pump. Findings from the paper are supposed to provide a theoretical basis for the following experiments and to improve the life of gear.
