摘要
针对现有一款冠簧插孔出现分离力过大导致易磨损以及寿命短等问题,提出一种参数化仿真优化方法。首先对现有冠簧进行参数化建模,并利用ANSYS Workbench软件对其进行多目标优化分析,最终选取软件拟合的最优参数作为冠簧结构设计的相关尺寸,优化结果表明,优化后的冠簧最大应力减小59.9%,分离力在满足企业要求的前提下减小62.4%,可靠性得到极大提高。最后通过试验验证,进一步验证了仿真优化结果的准确性。本文的研究成果为后续冠簧及相关产品的设计提供了新的设计思路。
In this paper,a problem of easy to wear and short life is caused by the large separation force of the existing crown spring jack,So we put forward a parametric simulation optimization method. Firstly,the existing crown springs are parametrically modeled,and the multiobjective optimization analysis is carried out by ANSYS Workbench software. finally,selecting the optimal parameters of software fitting for the relevant dimensions of the crown spring structure design. The results show that the maximum stress of the optimized crown spring is reduced by 59.9%,and the separation force is reduced by 62.4% on the premise of meeting the requirements of the enterprise,so the reliability has been greatly improved. Finally,the accuracy of the simulation optimization results is further verified by experimental verification.The research results of this paper provide a new design idea for the design of subsequent crown springs and related products.
