Analysis on vibration and stability for tractor-implement systems in high speed running

本文对高速拖拉机机具系统的振动特性和制动性能进行了分析。利用坎贝尔图分析了拖拉机底盘在转动和平动时的固有频率，并分析了各加速度波的时域相位。分析了驾驶员座椅在不同路况下的振动特性。在此基础上，分析了牵引车本身和牵引车-挂车组合的制动性能。从而为拖拉机操作人员的农业安全和舒适提供了一些有价值的数据。

In this research work, the vibration characteristics and braking performances were analyzed for high speed tractor-implement systems. The natural frequencies on tractor chassis for rotational and translational motions were analyzed by using Campbell diagram and phase of each acceleration waves in time domain. The vibration characteristics of operator seat on the several road conditions were also analyzed. Furthermore, the braking performances were analyzed for the tractor itself and tractor-trailer combinations. Consequently, the several valuable data on agricultural safety and comforts for the tractor operators were obtained.
