Taking the optimization method of aluminum alloy frame structure as the research object,a successive approximation topology optimization method was proposed.According to the benchmark electric vehicle body,topological design space was obtained,and then the topological optimization model of vehicle body structure under multi-working conditions was established.Firstly,the design space was divided into different regions.Then,based on the force transmission path,successively design topology for doors,ceilings,front and back ends,and replace the original structure.Finally,the resultswere obtained.After the results were analyzed,a concept body structure was proposed and compared with the conventional topology method.The results show that the proposed method is more efficient and the results are easier to "translate".The bending stiffness and torsional stiffness of the vehicle body structure are improved,the method provides a new way for the design of the concept vehicle body.

甲烷是一种理想的低碳代用燃料,但其在空气中燃烧缓慢,为改善这一缺陷,可采用甲烷氩气循环发动机的新概念.作为其理论研究基础,本文对比了甲烷在空气中和在氩氧混合气中燃烧的差异.发现层流火焰速度峰值从初始压力PO=0.1MPa时空气的接近40cm/s增加到氩气的超过70cm/s,PO=0.3MPa时则从25cm/s增加到超过55cm/s；燃烧压力峰值也从初压0.3MPa时空气的1.44MPa提高到氩氧混
本文根据多学科协同优化设计特点，基于综合评价思想，结合层次分析法，建立内燃机主承力结构响应协调性评价体系，以对结构强度、变形、振动、密封、润滑、质量进行综合协调评价。首先总结分析主承力结构设计要求、工作特点及失效形式，根据系统性、实用性、层次独立性等标准选择评价指标及其对应评价方法，建立总目标与子目标评价框架；定义各层间协调因子数学模型，完成响应协调评价体系构建。该体系可对不同内燃机主承力结构进行
在本文借助STAR-CCM+软件对压气机性能进行CFD分析。首先通过软件对某增压器三维模型进行表面处理,修补模型表面并进行必要的简化处理,然后用布尔运算将模型中压气机壳体与中间壳体合并为一个体,抽出压气机壳体、中间壳体及叶轮三个体形成的流体域。对于分割好的模型,将流体part定义为region以便进行后续的计算。然后利用软件定义进出口边界及叶轮转速,从而模拟了特定转速下压气机的性能。最后,对仿真模
