农用运输车车架振动的试验研究

Test Study on Frame Vibration of Agricultural Transporter

通过道路行驶随机振动试验，测试了农用运输车车架不同位置点的振动响应并作了频谱分析，计算了悬架系统和动力传动系统的频率特性。研究结果表明：悬架系统对车架的低频振动有较大影响。

By the road driving random vibration test on a 4-wheel agricultural transporter, the vibration signal from different positions of frame is analysed and compared with the frequency characteristics of power transmission system and suspension system. The study results show that suspension system mainly affects low frequency vibration of frame and power transmission system has an important effect on high frequency vibration of frame.
