为优化楔块式单向超越离合器的结构参数,根据漂浮式微型波力发电装置对超越离合器的要求,建立楔块式超越离合器结构参数的数学模型。以体积最小为优化目标,建立接触疲劳强度和各个尺寸的约束条件,并利用Matlab软件的优化工具箱求解数学模型。最后将常规设计参数和优化设计参数进行比较,结果表明:优化设计的体积只有常规设计的72.33%;漂浮式发电装置的传动系统结构更加紧凑,质量更轻。

In order to optimize the structural parameters of sprag overrunning clutch, in compliance with the requirements ofoverrunning coupler to the floating micro-wave power device, the mathematical model of sprag overrunning clutch structure parame-ters is built. The design aims to minimize the volume, establish the constraint conditions about contact fatigue strength and varioussizes and use Matlab optimization toolbox to solve the mathematical model. Finally, optimization design parameters are comparedwith the conventional design ones. The results show that the volume of the optimization design is only 72.33% of the conventional de-sign, and the optimized design structure makes the floating power transmission device more compact and lighter.
