| 摘 要： | 以北京前门投入运营的"铛铛车"车轮为研究对象,从降低"铛铛车"在运行中产生的轮轨接触噪声的目的出发,将最优化理论运用于"铛铛车"车轮断面外形设计,建立了以车轮断面外形几何参数为设计变量、车轮结构振动辐射噪声最小为目标函数、承载强度为约束的数学模型,编制了相应的算法,得到了车轮断面外形几何参数的最优解,结果表明优化后车轮的声功率水平比原始车轮减小了30%,降低了车轮的振动噪声.

| Abstract: | In this paper,the tram wheel put into operation recently in Beijing Qianmen Street was regarded as an object of study,and with the purpose of reducing wheel/rail contact noise emitted from tram travel,the optimization theory was introduced for optimal design of tram wheel cross-sectional shape.Geometric parameters of wheel cross-sectional shape were used as the design variables,and the minimal noises emitted from wheel structural vibration was considered as the objective function,while load strength was con... |
