To reduce the change of position and orientation of rocker-bogie lunar rover
which serves as the platform for the on-board science instruments on the uneven terrain
the structure parameters of rocker-bogie suspension are optimized. The kinematics parameters are defined based on the simplified rocker-bogie suspension structure
the kinematics model of rocker-bogie lunar rover is established with coordinate transformation
and the equation of position and orientation
expressed by the suspension kinematics parameters
is attained based on kinematics modeling. Taking vertical displacement and pitch angle change of the body as a multi-objective function
and the suspension parameters as design variables
a multi-objective optimization model is constructed
furthermore
the optimization solution is accomplished by the MATLAB optimization toolbox. The simulation analysis of lunar rover is carried out using ADAMS with initial value and optimization value
and the results show that the change of position and orientation of rocker-bogie lunar rover is reduced obviously after optimization.
