【摘要】 本文针对铁路客车空调机组的振动性能进行了研究,通过试验确定了其在各方向上的固有振动频率,并首次结合铁路客车的振动试验结果,对客车运行条件下车体振动可能对空调机组产生的影响进行了分析。认为应改善空调机组的垂向振动特性,避免产生共振。更多还原

【Abstract】 The aim of this thesis is to study the vibration performances of air - conditioning unit for railway. Nature vibration frequencies of them in different directions were determined by doing test.Associated with the vibration test results of railway passenger car for the first time, the author analyzes the possible influence of car body’s vibration on air-conditioning unit during the car’s operation and thinks that we should improve the vertical vibration characters of air-conditioning unit in order to avoid resonance.更多还原
