摘　　要：本文利用德国朗德公司的振动及噪声虚拟测量系统及KSTLER公司的压电加速度传感器对某车型进行了振动测试。对其运行过程中出现的颤动进行了专门测量分析,针对颤动现象,运用自相关、互相关及自功率谱密度函数分析手段,确定车辆颤动加速度共振频率为11Hz。文章还从降低车厢声共振的角度提出铁路客车软卧车厢内的长、宽、高尺寸要尽量不相同。本文的研究成果可为高速铁道车辆的振动分析研究提供参考。The vibration of a certain type of railway vehicle is measured with vibration and noise visual measuring system from Landtop in Germany.The shiver process of the vehicle is especially recorded. By analyzing with the tools as auto-correlation, cross correlation and auto-power spectrum density function, the cause of the shiver is made certain. It is vehicle-bridge coupling resonance, and the acceleration resonant frequency is 11 Hz. The length of the couch should be different in order to reduce its sound resonance effect. The result of this paper can also be used as reference for the vibration analysis of high speed railway vehicles.
