Abstract: To reduce the manpower and material resources costs,and to provide a scheme and feasibility basis for optimizing the component of servo crank press machine's mechanotronics,the digital integrated simulation system of crank servo press was developed based on Simulink,and the application analysis of virtual manufacturing on this system was accomplished.This system was composed of three parts:motion control,high power electric drive and mechanical transmission.The motion control portion combined two driving mode of constant speed and variable speed.The permanent magnet ac servo system and motor combination based on electronic flywheel were introduced into electric drive system,in which the double controls structure of outer speed loop and inner current loop were adopted for permanent magnet ac servo system,and the variable parameter PI regulator was introduced.The mechanical transmission portion adopted a crank link mechanism.The results showed that the working efficiency of servo press by using variable speed drive working mode was higher than using constant speed drive mode under the same stamping speed.Besides,its driving system was more energy efficient with variable speed drive mode in a work period.It provided evidences for further improving the manufacturing efficiency of servo crank press machine.
