摘　　要：为研究内燃机车司机室振动现象产生的原因,发现其中柴油机激励有很大影响。通过计算柴油机惯性力、惯性力矩和倾覆力矩,分析了柴油机的振动激励力。建立某调车机车的有限元模型,分析了底架固有模态;并设计了合理的谐响应工况研究柴油机激励相位与大小对司机室振动的影响。研究表明柴油机激励的相位对司机室振动幅值影响不大;当其各支承上激励相位相同时,司机室振动幅值最大。In order to study the cab vibration of diesel locomotive, diesel engine excitation plays an im- portant role. By calculating inertia force and inertia moment and overturning moment of diesel engine, the vibrate exciting force of diesel engine is analyzed. Established the finite element model of a shunting loco- motive, analyzed the underframe mode of vibration, designed proper harmonic response to study the cab vibration caused by phase and size of diesel engine exciting force. The studies show that phase of diesel en- gine exciting force impact little on cab vibration; and when the bearings of cab had exciting forces with the same phase, the cab vibration reached the maximum amplitude.
