摘　　要：针对挤吹线缆架抗支撑能力不足、使用过程中产品变形量大等问题,课题组对含不同加强筋结构的挤吹线缆架在支撑载荷作用下的力学性能进行了数值仿真研究。利用UG(Unigraphics NX)软件建立了2种挤吹线缆架的有限元模型,在受力面上设计了2种不同的加强筋结构;采用正交试验法设计L9(4^3)正交表对其主要设计参数进行优化分析;仿真计算了挤吹线缆架在支撑载荷下的响应,比较分析了2种不同模型下的应力分布。实验结果表明加强筋的脱模斜度对产品变形量的影响最大,受力面加强筋的角度对产品所受应力的影响最大。加强筋设计为凸起结构时更利于实际生产及产品的使用。In order to solve the problems of insufficient supporting capacity and large deformation of blowout cable frame in application,the mechanical properties of the blowout cable frame with different stiffener structures under the support load were studied by numerical simulation.UG software was used to establish the finite element model of two kinds of extruded blow cable frame,and two different stiffener structures were designed on the stress surface.L9(4^3)Orthogonal table was designed by Orthogonal test method to optimize the main design parameters.The response of the blowout cable frame under the support load was calculated by simulation,and the stress distribution of two different models was compared and analyzed.The experimental results show that the release slope of stiffener has the greatest influence on the deformation amount of the product,and the parameter R1 of stiffener on the stress surface has the greatest influence on the stress on the product.When the stiffener is designed as a raised structure,it is more conducive to actual production and application.
