提出了一种斜撑离合器正向设计的校核方法与评判策略,用于离合器服役性能的预测与评判。将离合器楔块与内外轴作为整体研究对象,提炼出综合应力、接触应力、楔角、升程百分比4项指标,并推导出对应的校核计算模型;进一步地,归纳出离合器正向设计优劣的综合评判策略。以J8331型号的离合器为例,从理论解析与有限元仿真两方面入手,对比验证了本文方法与策略的可行性,并据此得出载荷与上述指标之间呈非线性正相关性的动态规律。
A verification and evaluation method for the top-down design of sprag clutches is proposed for the prediction of the clutch performance. The research targets are associated with sprag
inner and outer shafts
so four mathematic verification models are derived from von Mises stress
contact stress
gripping angle
and percent of sprag rise
which are refined from the comprehensive performance. Taking the clutch of model J8331 as an example
the feasibility of the method and strategy proposed in this study is compared and verified through theoretical analysis and finite element simulation. Based on this
a dynamic law of nonlinear positive correlation between load and the above indicators is obtained.
