摘要：
In order to study effects of time delay on stability of a semi-active suspension system, a 2-DOF semi-active suspension model with time delay was established, and sufficient and necessary conditions to satisfy all delay stability of the system was derived by using the improved all delay stability algebraic criterion according to the stability theory of time delay system, and the range of controllable damping value was obtained. Aiming at semi-active suspension parameters not satisfying the all delay stability condition, the stability switching point analysis method was proposed to solve and obtain the actual stability switching point and its stability interval. The time-domain simulation showed that the generation of time delay does not lead to the deterioration of suspension performance under the all delay stability condition; under the condition of non-all delay stability, the performance of suspension drops with increase in time delay and worsens sharply when time delay exceeds the stability switching point. © 2021, Editorial Office of Journal of Vibration and Shock.
