Abstract：In order to optimize the spatial design of grader front axle , a model of front axle is extracted accordingly to analyze its structure and spatial kinematic pairs .A front axle kinematics model is built with the software CATIA DMU ( Digital Mock-Up) module .The kinematic simulation is performed based on the prototype model,applying reasonable kinematic pairs and driving commands .Through the motion simulations,the study acquires the steering angle relations of inner and outside wheels .The steer cylinder parameter relations on complex space movement are also acquired .These provide the basic data for cylinder parameters .The enveloping solid for tire key parts is also established and the dynamic gap is analyzed ,which offers reference and basis for the complex front axle and middle scarifier designs .
