The polyurethane foam with different structure was prepared by one-step foaming process, and the acoustic properties of the foam were measured by impedance tube, using sound absorption coefficient as the measure index, the effects of manufacturing temperature, ratio of polyols to MDI and total mass (density) on the acoustic properties of polyurethane were analyzed by experimental optimization design. The test results show that the ratio of polyols to MDI is the most important factor affecting th...

At the design beginning of a certain type of passenger car, the noise spectrum of the air intake system is analyzed. Firstly, the structure model and acoustic model are established by GEM3D, and then GT-Power was used to analyze the noise of the system and simulate the full load condition of the engine. The sound pressure levels of the third, sixth, ninth, and twelfth order nozzle noise at 1000-6000r/min were respectively calculated and optimized. Comparing the sound pressure levels, the results...

To study the temperature of the cylinder block and cylinder head, temperature analysis was carried out for the engine based on FEM. The temperature and convection heat transfer coefficient boundary were obtained by CFD analysis. Then the engine temperature analysis was carried out by the software ANSYS and the accurate temperature field distribution is obtained which provides technical guidance for the performance improvement of each part of the engine.
