内燃机车弹性司机室隔振降噪探讨

Discussion on vibration isolation and noise reduction of elastic cab of diesel locomotives

以某型内燃机车为研究对象,简述了内燃机车弹性司机室的结构与设计原理,对采用4个弹性元件为隔振方案的司机室及其降噪方法进行了探讨,给出了相应的分析过程及试验验证结果,为弹性司机室在机车中的应用提供了参考。

Taking a certain type of diesel locomotive as the research object,the paper briefly describes the structure and design principle of an elastic cab of diesel locomotive,discusses the vibration isolation scheme and noise reduction methods of the cab with four elastic elements,and introduces the analysis process and test verification results,which provides a reference for the application of elastic cab to locomotives.
