摘要
摩擦离合器扭转减振器是汽车传动系减振系统中一个重要的部件,但其扭转刚度计算方法在工程上尚未得到很好解决。分析扭转弹簧参数与扭转特性曲线的映射关系,建立离合器扭转弹簧多目标工程约束模型,提出一种满足多目标工程约束的扭转刚度计算方法,最后进行数据对比。数值计算表明,此方法在设计精度和计算效率相比较于常规的简单固定约束弹簧自由长度和弹簧外径方法高。此外,还分析了旋绕比C对离合器扭矩容量的影响,计算结果表明,离合器扭矩容量随旋绕比C的增大而减小。
The clutch torsion damper is an important part in the automotive transmission system.However,the stiffness calculation method has not been solved very well.In this paper,the mapping relationship between torsion spring parameters and torsional characteristic curves is analyzed,and a multi-objective engineering constraint model for clutch torsion spring is established.A torsional stiffness calculation method for multi-objective engineering constraints is proposed.The numerical results show that the design accuracy and computation efficiency of this method are higher than that of the conventional simple fixed constraint spring free length and spring outer diameter method.In addition,numerical also shows that the torque capacity of clutch decreases with the increase of spring index.
