Motor drive control is the major study field in the development of lunar rover. Based on the double-closed DC loop adjustable-speed system, a motor drive simulation module using a position recursive PID control algorithm is developed, which is integrated into the multi-body dynamics simulation system, to carry out the whole lunar rover simulation. And the cruise process of lunar rover locomotion in the complex lunar terrain is simulated in a virtual environment.

Misalignment on sun gear in planetary gear is easily occurred and it usually causes serious problem of work efficiency and lifetime with the change of planet load sharing. For study on the influence of sun gear misalignment on load sharing, multibody dynamics simulation is employed in this paper. First of all, 3D geometry model of planetary gear is built by Solidworks. Based on 3D model, multi-body dynamics model of planetary gear is built by MSC.ADAMS and calculate meshing forces between sun gear and planet gears with each type of sun gear misalignment which are angular, radial and axial type. Based on this meshing force result, load sharing factor is calculated and the results of influence of each misalignment type to load sharing factor is obtained. Finally, gear lifetime is estimated by AGMA gear fatigue strength estimation method with load sharing factor. According to the results, radial misalignment is the most influence to load sharing factor and gear lifetime.

The motion of amplification frame of dumper was simulated by multi-body dynamics simulation software ADAMS, and the danger working conditions of amplification frame were calculated. The stress of amplification frame was simulated and analyzed by Optistruct software. The results show that the stress distribution in amplification frame is not uniform and it is big in the middle and small in the edge zeros. The structure of amplification is optimized according to the simulation results. The utilization ratio of the material increases and the cost of production decreases after structural optimization.

Engine Crankshaft

Crankshaft is one of the key parts of the diesel engine. Several causes would be lead to the failure of the crankshaft. A novel strength analysis method is used for crankshaft high cycle fatigue simulation of the diesel engine based on flexible multi-body dynamics in this paper. In order to investigate the fatigue strength of other parts of the diesel engine at the same time, a complete coupled dynamic model of diesel engine crankshaft and block is built and coupled dynamics simulation is carried out. Then dynamics calculation results of each part is extracted for high cycle fatigue analysis and the reliability research of the crankshaft, The simulation results show that, the minimum safety factors of the crankshaft is 1.301, it meet the strength requirements, the safety factors of the block and the cap could be calculated at the same time. These suggest that this method can guide the design of the diesel engine crankshaft and has gained significant importance in practical study.

The rubber track system can be quickly swapped on the tyres, exerting a smaller ground pressure while generating a greater adhesion to solve the problem vehicles faced in traversing rough and difficult terrain. This paper will discuss the influence of rubber track system on the ride comfort of engineering vehicles with rigid suspension. First, a multi-body dynamic model of the rubber track system and a mathematical model of contact between the ground and the track are established, and then the macro commands are programmed to add many complex contact forces. Moreover, by using the method of physical prototype obstacle testing, the correctness of the simulation model is validated. The ride comfort of the engineering vehicle when equipped with rubber track system is explored by the method of the multi-body dynamics and real vehicle test. The research shows that a flexible roller wheel system can significantly improve the ride comfort of the engineering vehicle when compared to wheeled vehicles. When the vehicle speed is low, the weighted root-mean-square acceleration of the wheeled vehicle and tracked vehicle is almost the same. At the same time, it is verified that the ride comfort of the steel-chain tracked vehicles is worse than that of rubber tracked vehicles, due to the polygon effect. Through the multi-body dynamics simulation of the virtual prototype, we can predict and evaluate the ride comfort of vehicles, saving the cost of testing and obtaining the actual experimental data, which has great significance for the research and development of vehicles.
