英文摘要： Equipment manufacturing is one of the core parts of the manufacturing industry. It is of great importance to reducing energy demands and improving energy efficiency for the realization of low carbon economy development. This project aims at proposing design methodologies for highly energy efficient main transmission system of large scale servo press. The research is to be carried out in the following aspects: based on the characteristic analysis and energy dissipation modeling of impacts between joint elements induced by clearance, the influences of the structure and dynamic features of linkage mechanism on joint impacts are to be studied. Then, the relations between forming performance, energy efficiency and mechanism and joint design parameters are to be modeled, and based on which, the topological structure design method of mechanism and joints for energy efficiency optimization will be studied. The relations between stress distribution, surface topography, wearing, lubrication and frictional energy dissipation of major friction pairs of the main transmission system under conditions of large scale and discontinued heavy load will be studied. The complex influences of friction on mechanism energy dissipation are to be revealed. The simulation model of friction energy dissipation of the rolling guide of the slide block with considerations of impacts from multi-source motion error and eccentric load conditions is to be developed, and based on which the influences of rolling guide structure design, frame structure design and assembly design on the rolling guide friction energy dissipation will be analyzed. Then, the method for low energy dissipation friction pair design of the main transmission system will be studied. The coupling model of servo motor efficiency, mechanism structure and load spectrum is to be developed, and based on which the influences of mechanism features on servo motor load are to be studied for energy efficient coupling design of the mechanism and the servo unit. Based on the above research, this project is expected to provide theoretical basis and methodologies for development of highly energy efficient large scale servo press.
