An inverse algorithm of nonlinear load-displacement for a slotted disc spring geometric design

A geometric design algorithm for a slotted disc spring is proposed in this study. By using the proposed algorithm, all geometric dimensions of a slotted disc spring can be parameterized to satisfy a target nonlinear load-displacement function. This target nonlinear load-displacement function is plotted using the available prediction formulation. The defined geometric dimensions for the target function are then purposely set to be unknown design variables. Inversely, only the target function is referred to in order to propose a set of geometric dimensions of a slotted disc spring that satisfies the plotted target function. A comparison between the target function and the predicted function that are plotted using the calculated dimensions from the proposed algorithm are shown. Both design variables that are used to plot the target and are calculated from the proposed algorithm are also compared to validate the effectiveness of the proposed geometric design algorithm. These comparisons show the effectiveness of the proposed algorithm that enables inverse calculation to propose geometric designs by only having a given target nonlinear function.
