The research is a passing mechanism of one new entertainment machine .It can deliver the ball to the destination by the chain wheel which can drive a track in a large angle of elevation .Through the UG6.0, one model basis on the mechanical engineering materials is accurate. It can pass the assembled passing crawlers and racks into ANSYS, at the same time it can also have a static analysis on the track firstly after the repair. Due to the mechanical engineering materials we have three operating modes that can find out the most dangerous place. With the support of the crawler calculation results, it can compute the stress condition of a rack in travel to demonstrate the feasibility of this passing scheme.

The Finite Element Model

Conical picks are the key cutting components used on roadheaders, and they are replaced frequently because of the bad working conditions. Picks did not meet the fatigue life when they were damaged by abrasion, so the pick fatigue life and strength are excessive. In the paper, in order to reduce the abrasion and save the materials, structure optimization was carried out. For static analysis and fatigue life prediction, the simulation program was proposed based on mathematical models to obtain the cutting resistance. Furthermore, the finite element models for static analysis and fatigue life analysis were proposed. The results indicated that fatigue life damage and strength failure of the cutting pick would never happen. Subsequently, the initial optimization model and the finite element model of picks were developed. According to the optimized results, a new type of pick was developed based on the working and installing conditions of the traditional pick. Finally, the previous analysis methods used for traditional methods were carried out again for the new type picks. The results show that new type of pick can satisfy the strength and fatigue life requirements.

Periodical mixers are considered. The expediency of developing a new type of mixer is presented. Features of the material movement in the mixer allow to speak about the presence of elements of a gyroscopic effect. The mixing chamber is rotated by means of belt, chain and conical transmission. The resulting complex spatial movement of material particles can be controlled by a frequency Converter and the selection of appropriate gears or using a belt drive. An algorithm for modeling the drive unit of a mixer with a bidirectional rotational effect on the material is presented. The features of the drive unit and its components are considered. The task is to build a model of deformation of the drive unit of the mixer. The finite element method (FEM) for the drive unit of the mixer is used. Machine experiments are performed that implement fatigue calculations of the drive unit with a study in the SolidWorks Simulation environment. The results of static analysis of the drive unit operation in determining the deformation, static analysis of the drive unit operation in determining the voltage with varying torque are obtained. A variant of static analysis is presented when using a belt drive instead of a gear drive. The practical implementation of the mixer drive unit in metal is shown. Conclusions on modeling are made.
