载货车驾驶室悬置测试与分析

Test and Analysis on Truck Cab Suspension

针对某款搭载新型驾驶室后悬置的载货车,为研究其振动特性的改善效果,以原型车以及一款同类车型为对标车,进行匀速工况下的道路平顺性试验,对测得的加速度信号进行分析、对比,得到测试车型的平顺性,整车振动较为恶劣的部位以及振动传递过程中隔振率较低的减振部件,进而提出驾驶室悬置系统的改进方向以及引起较大振动的来源,为今后同类车型的振动诊断与改进提供方法与思路。

For a new cab rear suspension with the truck, in order to study the vibration characteristics of the improvement effect to the prototype vehicle, with a vehicle for similar models for benchmarking, the uniform condition road ride comfort test, analysis on comparison of the acceleration signal measured, and get the test vehicle ride comfort, the transfer process of vibration isolation rate lower vehicle vibration damping components more adverse position and vibration, and then put forward the improvement direction of cab suspension system and cause large vibration source, for vibration diagnosis of similar models in the future and provide methods and ideas for improvement.
