| Abstract: | The experimental and numerical approaches are applied to investigating the pressure transient in the hydraulic transmission system.The closure time up to 0.Ims is experimentally achieved.The comparison of the observed,predicted and estimated maximum pressure shock shows good agreement. A computer code is developed for predicting, preventing and controlling the pressure transient. |
