The invention discloses a robust design method for positional parameters of front vehicle wheels. In the method, a robust design model for the positional parameters (a king pin inclination angle, a king pin caster angle, a front wheel camber angle, and a front wheel toe-in) of the front vehicle wheels is established by taking a multibody system dynamics theory as a basis, comprehensively considering the synergic relationship among a steering system, a drive system and a suspension system, analyzing the dynamics characteristics of the positional parameters of the front wheels under motor steering, straight running, wheel hopping and other various running states, integrating uncertain factors, such as the manufacturing errors of a steering trapezoidal arm, the assembling errors of a steering knuckle, a fit clearance between a steering mechanism and the suspension system, a designed variable numerical range, the preferences of all subgoal performances and the like, and taking the minimum angle turning error, the minimum sideslip during straight running and the minimum front wheel pivot angle during wheel hopping in a steering process as optimization goals. The robust design method disclosed by the invention has the advantage of improving the design level for the positional parameters of the front vehicle wheels in China, and can be widely applied to design of various types of vehicles.
