摘　　要：拖拉机作为一种重要的农业运输工具,可在田间与不同农业机械配合完成相关农艺操作过程。目前,农机具主要以悬挂的形式与拖拉机连接,但在进行田间试验中会发生底盘倾覆问题,故改善拖拉机底盘的动态性能对于提高拖拉机稳定性具有重要意义。针对以上问题,提出了一种拖拉机底盘前悬机架模型用于设计拖拉机底盘防倾覆悬架,并建立了拖拉机液压前悬架平面内动力学的验证模型,对拖拉机底盘倾覆进行分析。通过数值模拟与田间试验相结合的方法进行模型验证与分析,结果表明:构建的拖拉机底盘前悬架模型能够准确地模拟高、中负荷配置下的拖拉机真实模拟系统行为。研究结果可为拖拉机底盘的优化设计提供参数借鉴与理论依据。The tractor,as an important agricultural transport tool,is used in the field in conjunction with different agricultural machinery to complete the relevant agronomic operation process.At present,agricultural implements are mainly connected to the tractor in the form of suspension,however,chassis tipping motion can occur during field trials,therefore,improving the dynamic performance of the tractor chassis is important to improve tractor stability.To address the above issues,this study proposes a tractor chassis front suspension frame model for the design of tractor chassis anti-tip suspension,and establish the validation model of tractor hydraulic front suspension in-plane dynamics,tractor chassis overturning analysis.Through the combination of numerical simulation and field test method for model validation and analysis,the results showed that the tractor chassis front suspension model constructed in this study can accurately simulate the behaviour of the real simulated system of the tractor under high and medium load configurations.The results of the study can provide a parameter reference and theoretical basis for the optimisation of tractor chassis design.
