A New Calculation Method of Diaphragm Spring Load-Deflection Characteristics

Abstract

The invention discloses a new method for calculating the load-deformation characteristic of a diaphragm spring. Firstly, the load-deformation characteristic curve of the diaphragm spring is solved; Structural parameters of the hole; analyzed the influence law of the conversion parameters on the load-deformation characteristics of the diaphragm spring; proposed and defined the influence coefficient of the separation finger; used matrix conversion to obtain the relationship between the peak value, inflection point load, valley value and conversion parameters for each item The separation refers to the relationship between the influence coefficient and the conversion parameter; the orthogonal test obtains the simulation analysis data; the multiple regression analysis method fits the function expression of the separation refers to the influence coefficient and the conversion parameter; the separation refers to the influence coefficient as a correction item of the separation refers to the part Based on the calculation formula of disc spring accurate algorithm S-W method, a new calculation method of diaphragm spring load-deformation characteristics is obtained. The invention can be used to guide the design work of the diaphragm spring, shorten the research and development period, reduce the design cost and improve the efficiency.

Description

technical field [0001] The invention relates to the technical field of characteristic calculation of diaphragm springs, in particular to a new method for calculating the load-deformation characteristics of diaphragm springs. Background technique [0002] A diaphragm spring is a nonlinear spring consisting of a disc spring section and a split finger section. Diaphragm spring has good non-linear characteristics, and at the same time acts as a compression spring and release lever, which reduces the number of parts, reduces the weight, shortens the axial distance of the clutch, and improves the reliability of work. Due to the above advantages, the diaphragm spring is an important part of the friction clutch. [0003] Clutch manufacturers usually use the disc spring approximate calculation method A-L method to calculate the load-deformation characteristics of the diaphragm spring. However, there is a large error between the load value calculated by the A-L method and the actual...
