油气悬架四连杆导向机构的设计

he guide mechanism of suspension system is critical to the performance of the suspension, which determines the riding comfort and control stability. This paper makes a deep research of a holistic transaxle suspension guide mechanism of a 45t artificial vehicle used for mining, and analyzes the choosing style of suspension guide mechanism. The models of anti-pitch and anti-roll are also set up in this paper to carry out the optimization design and dynamic design of the guide mechanism. the design method is proved by emulator to be practical. The anti-pitch vehicle model is based on the software of Matlab, and the optimization result is showed in the three-dimension picture; The analysis of anti-roll model is based on the Adams software, where three-dimension model is set up to analyze the three working conditions of speeding up, slowing down and steering. The result is showed by curves. Based on the above parameters, the designs of joins and rods structure intensity are carried out.
