Analysis of Water Hammer in Water-based Hydraulic Actuator System

Abstract

This study proposes a hydraulic pressure transient analysis of a low-cost water hydraulics actuator system. The objective of this project is to study the performance of the actuator under various circumstances. Water hammer is a problem that happened to all type of pipe that has the fluid flow on it. It is due to the pressure difference in the pipe which happened when the velocity of the fluid flow is suddenly stopped due to a closed valve. This effect will cause the damage to the pipes when the pressure exceeding the maximum pressure that can withstand for the pipe. The analysis of the water hammer is done to overcome this problem from happen in the pipeline especially in hydraulic system and it needs to create a simulation circuit of the hydraulic system. Simulation has been conducted for pressure at 50 and 100 psi at length of pipe 0.5 and 1.0 m length.
