摘要
对某轻型载货汽车进行不同工况的振动性能测试,分析评价其动力总成悬置的隔振特性、驾驶室隔振装置和悬架系统的隔振效率;基于MATLAB对振动加速度时域信号进行时域传递率和频域传递率分析。
The authors test the vibration performance of one light truck under different conditions, analyze the vibra- tion insulation characteristics of power assembly, evaluate the vibration resistance performance of cab＇s vibration isolation devices and assess the vibration resistance efficiency of suspension system. Last, they analyze the time-do- main and frequency-domain transmission efficiency of time-domain vibration acceleration signal based on MATLAB.
