复合材料商用车前下防护装置拓扑优化设计
Topology Optimization Design of Composite Material-based Front Underrun Protective Device for Commercial Vehicles
摘要
Abstract
To ensure a light weight,continuous glass fiber reinforced composites were used to replace traditional high-strength steel for the optimal cross-section design of the protective beam in front under-run protective devices for commercial vehicles.The equivalent static load method was adopted,and dis-placement responses at key moments from LS-DYNA dynamic nonlinear time-domain analysis were converted into equivalent static loads.For multiple working conditions,topology optimization with multi-algorithm and multi-material was conducted in the Optistruct static solver to minimize weighted flexibility,with volume fraction as the constraint.The results show that the double-hollow section ob-tained via the equivalent static load topology optimization method reduces the weight by about 40%,and its structural stiffness increases by over 23%compared to the C-shaped section obtained via the traditional static load optimization method,with significantly improved torsional performance.关键词
