【摘要】 介绍了车用涡轮增压器涡轮叶片一种新的设计方法。新设计的这种涡轮叶片截面形状为曲线形，叶片端部厚度减小，根部厚度增加，从而提高了叶片的自振频率，减小了叶片转动惯量，改善了涡轮工作的可靠性和发动机的加速性。该设计方法对于实现涡轮叶片的ＣＡＤ、ＣＡＭ有实用意义。更多还原

【Abstract】 A new design method of turbocharger vanes for motor vehicle is presented.The section of the newly designed turbine vane is of curve shape.The thickness of the vane tip is decreased while that of the vane root increased so as to increase the self vibration frequency and reduce the rotation inertia of the vane,and improve the operation reliability of the vane and the acceleration performance of the engine.This design method is of practical meaning for realization of CAD and CAM of turbine vanes.更多还原
