Abstract
Steering gear is an important machine for setting and changing the route of the ship, which is mostly operated by hydraulic pressure. In the steering gear using the hydraulic system, a lot of heat is generated and accumulated by the internal hydraulic flow with high pressure in hydraulic pump and actuators, which increases the temperature of hydraulic oil. Temperature increase of the steering gear changes the viscosity of hydraulic oil and adversely affects the entire steering gear. It is customary to measure and estimate temperature increase to determine the effects of temperature on the steering gear system.

In this study, temperature increase of steering gear system is obtained numerically by using the Ansys CFX and SimulationX.The goal of this study is to establish a method to obtain equilibrium temperature of the steering gear system through confirmation of the numerical results by comparing with experimental ones.

This study shows that the numerical result of the temperature is about 3.7℃ higher than experimental one, which is quite acceptable.
