摘　　要：随着科学技术的发展,国民生活水平显著提高,山地自行车爱好者不仅对于自信车的强度有着极大要求,针对其质量的要求也有所提高,推动着轻量化技术的向前发展。企业通过轻量化设计可以降低成本,提高生产效率,同时保证产品质量,以提高企业竞争力。本文以山地自行车结构部件为研究对象,通过Altair Inspire拓扑优化软件对其进行拓扑优化设计。将结构部件模型导入Altair Inspire中,设置模型材料,添加载荷、约束,确定设计空间,选择形状控制,以优化模型的最大刚度为设计目标对其进行优化设计。通过有限元分析,进行拓扑优化后对比优化结果,将结果几何重构,在满足强度要求和可靠性的前提下,减少零部件质量56.83%,提高自行车的质量和使用效果。With the development of science and technology,the national living standard has been significantly improved.The mountain bikers not only have great requirements for the strength of confident cars,but also improve their quality requirements,promoting the development of lightweight technology.Through lightweight design,enterprises can reduce costs,improve production efficiency,while ensuring product quality to improve their competitiveness.This paper studies the structural components of mountain bikes and designs their topology optimization by Altair Inspire topology optimization software.Import the structural component model into Altair Inspire,set the model material,add the load,the constraint,determine the design space,select the shape control,and optimize the maximum stiffness of the model.Through finite element analysis,after topology optimization,the results are compared to reconstruct the geometry,reduce the quality of parts by 56.83%while meeting the intensity requirements and reliability,and improve the quality and use effect of bicycles.
