Abstract
Based on the mathematical model of geometric relations of high-speed single-arm pantograph, structure parameters of the high-speed single-arm pantograph are optimized and designed applying multi-objective Optimization technology. Considering good contact of pantograph-catenary, rising height of pantograph and time of rising and dropping pantograph as the constraint condition, and considering the trajectory of pantograph head and the equivalent mass of pantograph as the target, a group of optimal structural parameters are gained combining with MATLAB software. The three-dimensional modeling of pantograph is completed according to the results of optimization. Applying virtual prototype technology to simulated analysis can verify the precision of the optimization results and methods.
