Cabinets of Comprehensive Inspection Train Random Vibration Analysis

摘要

In this paper an accurate of railway vehicles random vibration analysis method and engineering application systems is employed to do random vibration analysis, geometric models of electrical control cabinets of comprehensive inspection train is build. The model is excited by German low interference spectrum and 5 different results are calculated. As the speed increases vertical and lateral acceleration standard deviation are also increase and the lateral acceleration standard deviation of 220-250km/h more sensitive than the vertical. Cabinet installation support lateral acceleration standard deviation relatively large.
