摘　　要：由于农业生产环境较为复杂,田间地形粗糙度、拖拉机行驶速度、轮胎性能、后轴宽度和拖拉机底盘离地高度等田间因素会造成农业拖拉机操作时机身的振动,影响田间作业效果与驾驶员的操作舒适性与安全性。针对以上问题,探讨了拖拉机底盘离地高度对拖拉机横向振动的影响。研究结果表明:拖拉机车身横向振动随着拖拉机底盘离地高度的增加呈线性增加,将拖拉机底盘高度降低30cm(仅占当前高度的15%),将减少20%的拖拉机横向振动;拖拉机车身垂直振动几乎不受拖拉机底盘离地高度的影响。综上所述,拖拉机设计与生产优化过程中可以通过降低拖拉机底盘离地高度减少车身横向振动,进而提高拖拉机的驾驶舒适性。Tractor is an important agricultural machinery in agricultural production.As the agricultural production environment is more complex,the roughness of the field terrain,tractor driving speed,tire performance,rear axle width and tractor chassis height from the ground and other factors,will cause agricultural tractor operation vibration of the body,affecting the field operation effect and driver's operating comfort and safety.To address the above problems,this study to explore the tractor chassis height from the ground on the impact of tractor transverse vibration.The results show that the tractor body transverse vibration increases linearly with the increase of tractor chassis height from the ground,in medium-sized tractors,reducing the tractor chassis height by 30 cm(only 15%of the current height)will reduce the transverse vibration by 20%;the tractor body vertical vibration is almost not affected by the tractor chassis height from the ground.In summary,the tractor design and production optimization process can be reduced by reducing the tractor chassis height from the ground to reduce the body transverse vibration,and then improve the driving comfort of the tractor.
