Abstract: Using the fluid simulation software Kuli, this paper establishes a modeling for a cooling system of a passenger car gearbox basing on their test parameters and does simulation calculation and compares with the experimental results. It is showed that simulation value of the side tube number of the gearbox has 8.3% deviation in contrast to the experimental values and the simulation value of coolant flow rate of the oil cooler has a 8.3% deviation in contrast to the experimental value. The simulation result agreed with the experimental value, so the simulation modeling is proven reliable. The simulation research proposes a theoretical basis for the designing and matching of the cooling system of the transmission gearbox applied in the passenger’ vehicle. In addition, the simulation using the Kuli software can greatly improve the analysis efficiency and shorten the development cycle and saves experimental costs.
