Random vibration of multi‐span mindlin plate due to moving load

In this paper, the method of modal analysis is presented to study the random vibration of multi‐span Mindlin plates due to a load moving at a constant velocity. The moving load is considered to be a stationary process with a constant mean value and a variance. Four types of variances are considered in this study: white noise, exponential, exponential cosine, and cosine. The effect of both velocity and statistical characteristics of the load, and the effect of the span number of the multi‐span plate on the mean value, variance of deflection and moment of the structure are investigated. The results of the multi‐span Mindlin plate are compared with those of a multi‐span classical plate.
