A space kinematics equation of the front wheel’s steering rod mechanism was built through the steering rod mechanism of the rhombic vehicle that was symmetrical about front and rear.The virtual prototyping model was built by utilizing the dynamics analytical software ADAMS of mechanical system.It validated the kinematics equations’ correctness.Considering the length and initial location of the wheel links, the relation of steering angles when the wheel turned left and right was optimized as well as the variation of steering angle during the wheel bounded based on the genetic algorithm.According to the requirements of the rhombic vehicle,the length and initial location of the corresponding links were optimized,which provides a theoretic basis to the design of steering mechanism.
