Structural optimization is the subject of achieving the best performance for a structure with various constraints such as a given amount of material,limitation of peak stress and deflection.Based on strong demand of lightweight,low-cost and high-performance structures due to the limited material resources and technological competition,optimal structure design is becoming increasingly important for designers (Huang and Xie,2010).Among the different optimization techniques,sizing optimization has revealed to be interesting for structural engineering,since it offers to the designer the possibility to find out the most suitable thickness distribution of a structure that meets all specified requirements,while demands a minimum in terms of expenses such as weight,surface area,volume,stress,cost,and other factors.

基于噪声衰减量的隔声理论,通过研究小混响室声场均匀性,本文提出了一种整车隔声性能主观评价方法.该方法将两辆车同时停放在混响室,室内触发白噪声,车内主观评价车辆的整车隔声性能,从而分析空气噪声对车内声品质的影响.同时,本文对车辆的车内噪声进行了客观测试,结果表明白噪声激励下的主观评价结果与客观测试分析结果一致.
模态分析在轻型车开发过程中应用越来越广泛,是轻型车正向设计的一种重要手段.在对发动机激励深入了解的基础上,运用模态分析法,将轻型车转向柱总成模态规划在发动机怠速与常用转速点火激励频率之间,在实车状态下对转向柱总成进行模态、振动试验,试验结果证实了模态规划的合理性.
路面噪声的激励源及传达系统复杂,从路面传递给轮胎的力难以精确测量,因此,定量预测路面噪声非常困难.在工程上,为了定量、定性地预测路面噪声,常使用等价路面粗糙度来描述路面传递给轮胎的激励力.本文通过CAE模型、试验数据相结合的方法,论述等价路面粗糙度的概念,并在此基础上对悬架系统振动和车内噪声进行预测,确认了路面粗糙度的有效性.在悬架系统的设计阶段，使用等价路面粗糙度，通过数值计算和试验相结合的方法
