摘要
用实验方法研究手扶拖拉机－驾驶员系统的振动特性，测量了随机激励时拖拉机上１６个测点及人体上７个测点的加速度响应，得到了前１０阶模态参数，并与没有驾驶员的情况进行了对比。
The purpose of this study is to investigate the vibration characteristics of a walking tractor and its driver system, experimentally. The tractor and its driver were simplified as a multi degree of freedom, linear, discrete mass spring system. Responses of 23 points including 7 points of the driver’s body were measured for random excitation. First 10 modal parameters were given. The results have been compared with those without driver. This work is useful for human protection and the design of walking tractor to vibration.
