捷达轿车离合器膜片弹簧的设计与研究

Optimization Design and Research for the Diaphragm Spring of JETTA's Clutch

针对国产一汽大众捷达轿车离合器DSP210J型号的膜片弹簧生产中存在的实际问题,修正了目前国际上流行的膜片弹簧的理论计算公式Almen-Laszlo公式(简称AL公式),并对DSP210J型号的膜片弹簧进行了结构优化设计,提出了符合国内生产标准的理论计算公式。通过对优化后的膜片弹簧实体件抽样疲劳寿命试验,试制件的寿命有所提高,而且弹性衰减在国家标准要求的10%范围内。本文修正的公式在改变结构参数和修正系数后,还适用于其他型号的膜片弹簧,实现了厂内标准化,使DSP系列膜片弹簧的生产摆脱了经验、试制的方法,提高了生产效率,减少了试制次数。

The researched object in this article is the DS of the faw-volkswagen JETTA＇s DS clutch which have been made in our country. Revise the popular A-L formula for the DS at present in this article. Mean while, optimize and design the revised structure, then make sure where can the coefficient, standardization put in the revised formula.Revise the A-L formula, fin- ally completed the revised equation which can offer a theory basis to design the JETTA＇s DS. Experiment some of the revision DS, the fatigue life experiment proved the life ofworkpiece had truly enhancement, moreover the elasticity weakens in the request scope -10%.The research in this article have a great deal of practical significance for YI DONG company. After lots of research, Design and manufacture of 210J DS has got rid of the company only depend on the methods of transcendental and trial-manufacturing. So improved the production efficiency and reduced the times of trial-manufacturing
