A consideration of Frequency Analysis by Multiple Sinusoidal Input with the Amplitude Characteristics Obeying Beta Distribution.

Abstract

This paper describes a way of thinking about analyzing the vibration characteristics of a component by using multiple sinusoidal input . The amplitude of the input is obeyed beta distribution being nearer natural phenomenon. The characteristics of plural inputs are to be reflected by one waveform. By using this input data, the time of test is shorten than the case of using the data of real road surface. When we checked this result by using Bayes statistics, it was revealed that variance of the mensuration consequence was small.
