[Abstract]:With the development of synchronous belt transmission in the direction of high belt speed, long distance and high load, it is particularly important to analyze its dynamic characteristics. In this paper, the physical prototype of synchronous belt transmission is taken as the research object. Based on the theory of flexible multi-body system dynamics, the virtual prototype model of solid prototype is established by using RecurDyn software and the dynamics simulation analysis is carried out. Through the data analysis, according to the structural characteristics and dynamic characteristics of synchronous belt transmission, the optimal design of synchronous belt transmission system is carried out. The aim of reducing vibration and noise is achieved, which provides concrete guidance for the design, use and production of actual synchronous belt transmission. This paper systematically summarizes the development of synchronous belt transmission at home and abroad, studies the structure and performance of synchronous belt transmission, and gives the static performance evaluation and test method of synchronous belt. The forces of synchronous belt transmission and the meshing polygon effect are analyzed, and the transverse and longitudinal vibration models of synchronous belt transmission are established based on the flexible multi-body system dynamics theory. The finite segment method is used to discretize the flexible body with infinite degree of freedom. The general form of the dynamic equation of the free flexible body is given in combination with the principle of virtual displacement and the principle of Darnberg. The modeling method of rigid-flexible coupling system is analyzed and studied, which lays a theoretical foundation for the dynamic model of synchronous belt transmission and its dynamic simulation. Based on the finite segment method, the dynamic model of flexible multi-body system is established. The synchronous band is discretized into rigid band element and flexible connection model. The virtual prototype model is established in RecurDyn software and the simulation analysis of the motion process is carried out. The system dynamic parameters and dynamic parameter curves are obtained. By processing and analyzing the dynamic data, combining with the characteristics of synchronous belt transmission structure and dynamic characteristics, the starting mode is improved to avoid the exciting frequency. The design of synchronous belt transmission model is optimized by adding tensioning device and optimizing tooth shape angle. The simulation results show that the optimal design method can effectively avoid resonance and reduce vibration. In order to make the future research more general and close to reality, the further work and research direction based on the virtual prototype are put forward. The simulation results of virtual prototype of synchronous belt drive show that the method of establishing system model by using discrete belt element and flexible connection is feasible. It is also reasonable. This paper gives the general method and steps of visual research of synchronous belt transmission based on virtual prototype technology, which is a new method to study belt transmission. It also provides a good solution for the design and application of real synchronous belt transmission.
