Abstract

In order to meet the requirements of the lunar rover for energy saving and light weight, taking the energy consumption of driving motors as the objective function, the parameters of rocker-bogie suspension were optimized for rover passing obstacle condition. A parametric model was built for the rocker-bogie suspension, the conditions for rover-passing obstacle were analyzed, and a mathematical model was established for the multi-objective optimization of the suspension parameters. The maximum-minimum method was adopted to unify the multi-objective function to a single-objective function. The optimization analysis was performed by the sequential quadratic programming algorithm to obtain the optimal values of the suspension parameters. The results showed that the energy consumptions of motors during rover passing obstacle reduce significantly.
