Resistance numerical simulation and test of tractor intake system based on STAR-CCM
The main function of the intake system is to supply enough clean air to the engine,and its system resistance directly af-fects the intake volume,and then affects the combustion performance of the engine.Taking the intake system of a tractor as a re-search object,the flow resistance characteristic was simulated by STAR-CCM software.Through the flow resistance bench test of the intake system,the static pressure value maximum deviation of each measuring point between simulation and test results was 8.4%.The accuracy of the flow resistance simulation method of the intake system is verified,which can help to solve the problems of the minimum boundary design of the intake pipe and the resistance reduction optimization of the air filter,reduce the test cost and shorten the product development cycle.
