Lab-based Accelerated Vibration Testing for Articles in the Baggage Bay Area of the Motor Coach in the Vertical Direction
Motor Coach Industries Ltd. (MCI), a manufacturer of intercity coaches serving charter and tour operations, requires extensive field tests to validate the durability performance of coaches and components. To reduce the time and expense of these field tests, the intern will conduct mathematical analysis of the recorded acceleration signals in the baggage bay area of a motor coach. Using extensive acceleration data collected by MCI engineers, the intern will identify the predominant vibration modes and study the relationship among these modes. This internship project is the first step to developing a comprehensive lab-based vibration test method/spectrum that may minimize future field tests.
