On-orbit service technology can extend the working life of the spacecraft, and improve the ability to perform various tasks. Docking mechanism is the key equipment of the space docking. The cushion performance of the system determines the dynamic characteristics in the docking process, and it is one of the important factors influencing the docking success or not. It is established that mathematical modeling of the new grasping mechanism in the buffering process, due to lack of the experiment equipments, the dynamic simulation on computer is an effective method to test and verify the parameters or evaluate the performance of the buffer system designed. Simulation analysis is conducted to get the corresponding buffer force for four different sets of buffer parameter, and it provides important basis for docking cushioning structure optimization.

Combine harvester is the most widely used modern forest machinery; tracked and wheeled logging machine is the common stumper. But each type of logging machine has its shortcomings and therefore it is need to develop a combination of tracked and wheeled logging machine. This logging mechanism takes the form of tracked feet while preserving the flexibility of wheeled logging machine, and also it has the obstacle-crossing ability of tracked harvester. The most important indicator of the performance of this new logging machine is its trafficability in soft and uneven road. This thesis uses multi-body dynamic simulation analysis software RecurDyn to build up the 3D model of such four feet tracked logging machine, and analyzes its dynamical process when meeting ditch. Eventually the logging mechanism performance is got. The conclusions provide foundation for design of combined harvester with four tracked feet.

This study addresses a method to realize cloth dynamics simulation by using a wind noise method. Taken a 1/f noise as its 2D model, the 3D model of the discussed cloth is constructed. During its 3D simulation, some stochastic functions are employed to depict its stochastic ability. For the purpose of realism and simplicity, we attend to convert our dynamic simulation frames into animation film files. From the feedback, the constructed model is improved and the real time simulation is realized by reducing the calculation.
