Hydraulic damper control systems are applied to the elastic cylindrical steel storage tank's shock\|resistance. According to the analytical mechanical model, vibration analysis equation is established. Simulation calculation with time history is put up according to a storage tank whose cubage is 1,000 stere. The displacement and absoluteness acceleration of the non\|controlled tanks are compared to the controlled, damping effect is researched. Calculation result shows that the damping effect is good. According to the result, applied ranges of the parameters for the HDS are given.
