摘要
基于有限元优化技术,利用具有轴对称模型、非轴对称载荷的谐单元,采用圆弧和直线构建的辐板参数化车轮模型,将静强度、疲劳强度、车轮质量、限界等条件作为约束条件或优化目标,结合可行域空间的搜索方法和迭代方法,提出了一种车轮优化设计方法。该方法提高了计算效率,缩短了优化周期,减少了设计人员经验、专业技术不足对设计效果的影响,具有自动、可行、高效、性能优良的特点,可为车轮结构的快速化设计提供借鉴。
Based on finite element optimization technology,making use of harmonic element with axisymmetric model,non-axisymmetric load,adopting the wheel model with parameterized wheel web which is constructed by arcs and straight lines,taking static strength,fatigue strength,weight of wheels,boundary and etc as constraint conditions or optimization objective,combining searching method and iterative method of feasible region space,an optimized design method for wheels is proposed.The method improves calculation efficiency,shortens optimization period and reduces effects on design effect caused by designers’lacking of experience,professional skill.With features of automation,feasibility,high efficiency,excellent performance,the method can provide reference for rapid design of wheel structure.
