摘要
应用有限元分析理论模拟了摩托车脚蹬板在极限支撑驾乘人员载荷工况下的强度和刚度特性。在此基础上,以内部加强筋区域作为设计空间,采用变密度法对结构进行拓扑优化,同时依据优化结果对模型进行了重新设计及方案可行性的验证,解决了原始结构强度和刚度不足的问题。拓扑优化技术的应用缩短了该产品的研发周期,并为同类产品的设计提供了有效的方法借鉴。
By using FEA, the strength and stiffness characteristics of motorcycle foot-peda! under extreme loads conditions with driver and passenger were analyzed. Based on these, topology optimization was conducted with inner ribs as design domains using variable density method. Meanwhile, one new model was obtained according to the topological optimum results and the feasibility of structure is verified. The deficiency of strength and stiffness of previous design is resolved. In this way, it can shorten the development cycle and provide the theoretic guidance for the design of homogeneous products.
