基于刚柔耦合的HXN3司机室隔振系统多维度频率响应分析

针对HXN3型内燃机车出现的司机室振动较大问题,展开司机室隔振结构隔振性能分析。通过进行HXN3机车司机室振动试验,明确柴油机-发电机组作为振源的激励特性和振动传递特性。建立将司机室视为弹性体的多维度隔振结构动力学模型,计算该多维度(multi-dimension)隔振结构关键位置的频率响应函数。进一步分析HXN3机车司机室隔振结构对于柴油机-发电机组高频激励的隔离效果。

Multi-dimension frequency response analysis of a HXN3 locomotive cab based on rigid-flexible coupling theory

This paper is focused on the isolation property analysis on the HXN3 diesel locomotive cab isolation system for solving the cab excessive vibration problem. An experiment was conducted to investigate the vibration of the HXN3 diesel locomotive. A multi-dimension cab isolation kinetic model was established with considering the cab flexibility, and the vibration frequency response functions were calculated. This paper analyzes the isolation property of the cab isolation system under the high-frequency excited vibration.
