摘要: 模态是系统的“基因”,其与服役边界匹配的好坏,直接决定整个系统的动力学特性。以高速动车组转向架构架为研究对象,详细研究转向架构架系统模态匹配方法。探讨高速动车组转向架服役边界特征以及现有模态匹配方法;基于梁理论构建可变参数的转向架构架系统动力学模型,提出转向架构架服役振动环境再现方法,并利用转向架构架模态试验和线路振动试验数据对模型进行验证和修正;研究转向架构架关键几何参数对系统模态频率和振动传递特征的影响,识别转向架构架关键模态和结构几何参数。结果表明:基于梁理论的参数化模型能较好地反映150 Hz以内的构架模态信息,揭示转向架构架关键几何参数对系统模态频率和振动传递特征的影响规律。优化后的构架在38.3 Hz附近,振动幅值降低12.3%,关键位置应力幅值降低14%~17.6%。

Abstract: Modal is the “gene” of a system, and the quality of its matching with the service boundary directly determines the dynamic characteristics of the entire system. Taking the bogie frame of high-speed EMUs as the research object, the modal matching method of the bogie frame system is studied in detail. The service boundary characteristics of high-speed EMU bogies and the existing modal matching methods are discussed. Based on the beam theory, a parameteried model of bogie frame and a method for reproducing the service vibration environment of the bogie frame are constructed. The model is verified using the experimental results obtained from the modal tests and the field tests. The influences of key geometric parameters of bogie frame on the system modal frequency and vibration transfer characteristics are studied, and the key modes and structural geometric parameters of the bogie frame are identified. The results show that the parameterized model exhibits a high degree of fidelity in characterizing the modal information of the bogie frame within the 150 Hz frequency range, which is further used to study the influences of the key geometric parameters on the vibration modes and transmissibility of system. Moreover, for the concerned dominating frequency of 38.3 Hz, the optimized bogie frame can low the amplitude of vibration and dynamic stress of critical position by 12.3 % and 14%~17.6%, respectively.

Key words: railway vehicles, bogie frames, parameterized models, vibration fatigue, modal matching
