金属虐无级变速传动机理的数值分析

滑移角是带动动研究中一个非常重要的物理量，它的大小表示摩擦力方向的改变量，使力的分布错综复杂。作者论述了滑移角产生的原因，给出了带轮包角与滑移角的关系式，用龙格－库塔法计算出不同速比下的滑移角。在上述研究基础上，建立了金属带式无级传动装置关键部件－金属、金属块的力学分析模型。

Numerical Analysis on Mechanism of the Metal Pushing Type Continuously Variable Transmission

Continuously variable transmissions have attracted a great deal of interest in recent years because they shift with very little shock and offer significant advantages of acceleration performance and fuel economy for automobile.The slide angle is very important physical parameter in belt study. It's magnitude expresses the changing of direction of friction force's and makes the distribution of force very complicated. In this paper,the reason of the slide angle has been discussed. The formulae of wrapping angle relation with slide angle is put forward. The magnitude of slide angle is computed by used the Runge Kutta method in different speed ratios. On the basis of study a new descrete numerical analyse approach is proposed to analysis and calculate the tension and thrust of the key work piece's the metal rings and the metal blocks of the metal pushing type continuously variable transmission respectively under different speed ratios and torque ratios. The research result in this paper can be used to analyse the strength of the metal rings and the metal blocks and improve the load capability of the CVT gearbox. [WT5HZ]
