Abstract：The paper focuses on the stability problem that an inverted pendulum in an air spring vibration isolator connected in series with the inverted pendulum often moves to one side without going back to its initial equilibrium position or takes too long time to go back during use. The mechanical model for the stability of the inverted pendulum was established and the mathematical models of restoring force and restoring torque were deduced on the basis of an indepth analysis on the influence of each structure parameter of the vibration isolator on the stability of the inverted pendulum. By simulating and analyzing the mathematical models in consideration of the actual case, the main structure parameters affecting the stability of the inverted pendulum were found. The results show that the oscillating rod length of the inverted pendulum and the radius of the upper piston mainly affect the stability of the inverted pendulum.
