【 摘 要 】

This paper aims to research and analysis the tractor hydraulic suspension system stress. The hydraulics system was hooked on the latest developed hillside tractor chassis, this experiment used load test method and portable hydraulic testing instrument to test the cylinder movement process and force process. It can be concluded from the drawn curve that when the system loads 2940 Newton, the maximum working pressure is 4.4Mpa. When the system loaded 3920 Newton, the maximum load is 4.8Mpa. The pressure difference between the left and right levers is 2Mpa. The conclusion can provide data validation for the simulation analysis of tractor suspension system as well as an effective reference for the design scheme of tractor suspension system.
