Numerical analysis has been carried out to investigate thermal characteristics for hydraulic system in a special vehicle. Hydraulic system performance is largely affected by oil temperature, and there are considerable malfunctions in the system for high temperature conditions caused by heavy load and continuous operation. Hence thermal characteristics such as oil temperature and pressure drop in the system should be analyzed for efficient system development. Oil temperature variation with time is predicted with flow distribution in the oil tank. Local heat generation of pipeline, valves, and oil pump in the hydraulic system are considered with pressure loss. The results in the study can be applied to the design of optimal hydraulic system.
