基于ABAQUS的电子助力器副密封圈参数优化
Parameter Optimization of Seal Ring of Elec-tronic Booster Pair Based on ABAQUS
摘要: 电子制动助力器作为线性控制系统的一种解决方案，对结构可靠性提出了更高的要求，其中制动主缸密封皮碗的失效问题严重影响着制动总缸的抗失效性能。着眼于上述问题，本文以密封皮碗的材料形状、组装要求等参数设计正交试验，运用Abaqus模拟密封皮碗在位移下的受力过程并求出挤入处的最大Mises应力、挤入量和左侧密封处的磨损量；建立了影响因素与响应的二次响应回归方程；以密封皮碗防啃噬、防磨损相关效果为优化目标，使用遗传算法NSGA-II相关函数进行多目标优化，结合原尺寸结果挑选出帕累托最优解，使密封圈的抗失效性能得到了提高。
Abstract: As a solution of linear control system, electronic brake booster puts forward higher requirements for structural reliability, and the failure of the brake master cylinder seal bowl seriously affects the anti-failure performance of the brake master cylinder. In view of the above problems, the orthogo-nal test was designed with the parameters of the material shape and the assembly requirements of the seal bowl. Abaqus was used to simulate the stress process of the seal bowl under displacement and the maximum Mises stress, the extrusion amount and the wear amount at the left seal were obtained. The quadratic response regression equation of influencing factors and response was es-tablished. With the anti-gnawing and anti-wear effect as the optimization objective, NSGA-II corre-lation function of genetic algorithm was used for multi-objective optimization, and the Pareto opti-mal solution was selected based on the original size results, which improved the anti-failure per-formance of the seal ring.
