Design and Optimization of Lifting Mechanism in Hemming Machine Based on ADAMS

Hemming machine is an important method of craft of the hemming of automobile panels. According to the working characteristic of hemming machine, designing a kind of lifting mechanism of great reinforcement ratio that moves steadily. Establishing virtual prototype model of lifting mechanism with dynamic simulation software ADAMS, with such two factors stationarity and reinforcement ratio as indicators, having a comparative choice of the driving method of hemming machine, through the sensitivity analysis of the pressure of hinged rod by studying singular length of rod, finding out the appropriate designing variable, to which adding constraint condition and treating the average stress in the place where the rod hinges in a singular trip as the objective function, then having the minimum value optimization so as to get the optimum parameter of rod.
