The self-vibration characteristics and dynamic response of the time-varying structure are studied, and the self-vibration and dynamic response equations of the random time-varying structure are established. Considering that the load is a Markov stochastic process model, a stochastic time-varying structural dynamic reliability analysis method based on the model is proposed.
