Abstract

The invention discloses a design method of a streamline tunnel type turbocharger. The design method comprises the following steps: 1, forming a streamline tunnel turbine by applying a streamline tunnel type rotating fluid mechanical runner design and forming method; 2, on the basis of the structure of a traditional turbocharger, matching the streamline tunnel turbine with a traditional radial-flowtype air compressor, and obtaining a streamline type tunnel turbocharger rotor structure; 3, designing a turbine end volute according to the rotor structure obtained in the step 2, and performing aerodynamic performance simulation analysis; 4, establishing a rotor kinetic model according to the rotor structure obtained in the step 2; and 5, performing rotor dynamic characteristic simulation research according to the rotor dynamic model obtained in the step 4 to verify the stability of the rotor dynamic model. The design method of the streamline tunnel type turbocharger has the advantages thatthe strength is high, the turbocharger is not prone to damage, the weight can be reduced, and the cost is reduced.

Description

technical field [0001] The invention relates to the field of turbochargers, in particular to a design method of a streamline tunnel type turbocharger. Background technique [0002] As two major branches of internal combustion engines, gas turbines and piston internal combustion engines play a huge role in promoting the progress of human civilization. In order to obtain greater power, piston internal combustion engines often use turbochargers. It increases output power without changing engine emissions. A common exhaust gas turbocharger uses the inertial momentum of the exhaust gas discharged from the engine to drive the turbine to rotate, and then drives the coaxial impeller, which presses the air sent by the air filter to pressurize it into the cylinder, thereby increasing the engine speed output power. Traditional open and semi-open blade structure impellers have tip clearances, and the number and thickness of blades are limited by the level of material technology and t...
