一、随机振动简介1.随机函数以前我们对振动的研究中,遇到三种不同的干扰力的函数形式——谐波的、周期的和非周非期的。这些函数的共同特征就是对于任意时刻t都能预先给出函数值。这样的函
I. Introduction to Stochastic Vibration 1. Stochastic Function In the past, we encountered three different types of disturbing forces in the study of vibration - harmonic, periodic and non-periodic. The common feature of these functions is that the value of the function can be given at any time t. Such a letter
