Multidisciplinary Design Optimization of High-speed Pantograph Based on Collaborative Optimization Algorithm

Considering the influences of interaction and coupling among various disciplines on the design optimization of pantographs, the design demands of different working properties were analyzed. The multidisciplinary design optimization was adopted to establish optimization models of the system and subsystems that include the kinematics, statics, dynamics and control. According to the coupling relationship of design parameters of different disciplines, the collaborative optimization method was adopted to obtain the overall design optimization results of high-speed pantograph. The three-dimensional model of the pantograph was established to verify the validity of the optimized results by ANSYS. The results show that the multidisciplinary collaborative design meets the design requirements of the system and subsystems, and obtain the overall optimal solutions of the pantograph, which enhances the performance of the pantograph, reduces the fluctuation of the contact forces and increases the current collection quality of the pantograph and catenary.
