碳纤维-铝合金组合式节能赛车车架的设计与分析

Design and Manufacture of Composite Modular Frame

根据节能竞技大赛对赛车车架的要求,考虑到复合材料的轻质和可靠性,提出采用碳纤维复合材料和铝合金材料组成一体式车架的设计方案。依据对车架功能性和工艺性的要求,建立了车架实体模型。在ANSYS Workbench仿真平台中,对车架底板采用不同复合材料铺层形式进行了静力学分析,得到最优的碳纤维车架工艺实施方案。对碳纤维-铝合金组合式车架在不同工况下进行了有限元分析。验证该方案满足比赛对车架的使用性能和轻量化设计要求,为探讨复合材料在节能赛车车架中的应用起到了较好的借鉴作用。

According to the requirements for the frame of Economy Power Racing Car, taking into account the reliability of lightweight composite materials, a design using carbon fiber composites and aluminum material composite frame is proposed. Based on the frame functional and technological requirements, a frame solid model is established. In the ANSYS Workbench simu- lation platform, static analysis is done using different forms of bottom frame composite plies, the optimal carbon fiber frame process embodiments is got. Then carbon fiber composite - aluminum composite frame is put into different conditions combined finite ele- ment analysis. The program proves to meet the competition of the frame and lightweight design performance requirements, which provides a good reference of composite material in the application of economy power racing car frame.
