连续玻璃纤维复合材料前下防护梁多学科优化
Multidisciplinary Optimization of Front Lower Protective Beam Made of Continuous Glass Fiber-reinforced Composite Material
摘要
Abstract
To achieve a lightweight design of the front lower protection device for commercial vehicles,continuous glass fiber-reinforced composite materials were used to replace the steel beam,and a multi-disciplinary optimization method was applied for structural design.Mechanical properties of the com-posite material were tested,and failure criteria were established based on the Chang-Chang criterion.The mechanical response and failure modes of protective beams made of both materials were compared under the loading conditions specified in GB 26511-2011.By considering nonlinear crash perfor-mance and vibration characteristics,global response surface methodology within HyperStudy was em-ployed to perform multidisciplinary optimization and minimize structural mass.Results indicate that the beam made of composite materials,while meeting all performance requirements,achieves a 63.3%weight reduction and a 7.3%increase in the first natural frequency compared to the steel beam.关键词
