摘要
Abstract
The terrain on Martian is complex,leading difficulty for Martian rover to move.In order to improve performance of Martian rover mobility,Martian rover of China has been designed with active articulateness on the base of rocker-bogie suspension,and gained an active suspension.The active suspension is a new kind of suspension,which has its own special requirements.In order to minimize the body pitch,maximize the anti-tilting moment of wheel lifting operating mode and minimize the torque of the clutch between rocker and bogie,by selecting these three parameters as optimization objects,parameters of the suspension has been optimized.Because of the complex optimization function and the complex multi-constraints,genetic optimization has been selected as optimization method.The solution has been given,correlative simulations have been done,and the sensitivity of each suspension parameter has been analyzed.关键词
