膜片弹簧结构参数对其载荷——变形特性曲线的影响

Influential Tendency of Diaphragm Spring Structural Parameters upon Load-Deformation Characteristic Curve

汽车离合器膜片弹簧设计的主要任务,是确定各结构参数,以获得理想的载荷—变形特性曲线,并使其符合实车布置条件的要求。由于载荷—变形特性曲线的表达式长而复杂,故设计人员不能直接看出各结构参数对曲线的影响趋势。本文通过对表达式的数学分析,最后用一种直观的方法(影响趋势图)加以表达,从而使各结构参数对曲线的影响趋势一目了然。

Design of a diaphragm spring for automotive clutch is principally aimed at the determination of various structural parameters to obtain an ideal load—deformation characteristic curve which is in accordance with the requirements of the vehicle. The mathematic expression of the load—deformation characteristic curve is so long and complicated that the influential tendency of various structural parameters upon the curve is difficult to be discerned directly by designers. In this paper an intuitional way, an influential tendency chart, is proposed based on the mathematic analysis to the expression to clearly illustrate the influential tendency of structural parameters upon the curve.
