摘要
针对悬置系统设计过程中需要反复调整结构以满足刚度性能要求的问题,采用DOE和CAE技术对梯形橡胶悬置静刚度进行数值模拟试验,研究主簧的宽度、长度、厚度和角度等结构参数对悬置静刚度的影响,并根据试验结果进行因子分析,获得各结构参数对悬置静刚度的影响规律和相应的回归方程。运用回归方程针对实物样件目标刚度进行优化分析,能够快速获得各结构参数值,表明该方法便捷、有效,可为梯形橡胶悬置的设计制造提供参考。
As to the issue that the suspension system structure should be adjusted repeatedly to meet thestiffness performance requirements during the design process,the numerical simulation stiffnes of trapezoidal rubber suspension is carried out using DOE and CAE of structural parameters of main spring on the suspension static stiffness is studie,such as the width,length,thickness,and angle. The factors of every structural parameter are analyzed according to theresults of tests,and the influence of structural parameters on the static stiffness of suspension and the corresponding regression equation are obtained. The regression equations are used to optimize the target stiffnes of tlie sample piece, and the value of each structure parameter can be othat the method is of high conveniency and effectiveness. The result can provide reference for the designand manufacture of wedge rubber suspension.
