Calculation of Temperature Control and Heat Dissipation in Hydraulic System
摘要
Hydraulic system load will produce heat and bring a certain degree of temperature rise to the system, after the oil after the hydraulic system pipeline and main heat dissipation accessories back to the tank, and then be inhaled into the hydraulic pump cycle. The working temperature of the hydraulic system needs to be guaranteed in a certain range, which will result in the efficiency of the hydraulic system performance and the failure of the system, which will cause the system to work normally, and ultimately affect the safety of the aircraft and the task execution. Therefore, the hydraulic system needs to be thermal protection, so that the temperature control within a certain range. In this paper, based on AMESIM software, thermal power of hydraulic system is designed, the temperature control of the system is simulated, the dynamic temperature change and the heat dissipation demand of the system are obtained, which lays the foundation formal design of hydraulic system.
