- The main research is as follows : analyze and research the boundary constraint and the structure characteristic and segment the frame making use of the shell element , the pipe element etc . on the base of it the practical finite element model has been established ; analyze the mode of the frame by dint of the finite element model . and get the inherent frequency and the vibration mode of the frame . tentatively estimate the dynamic characteristic of the frame and analyze the inherent frequency that may be lead to the resonance
论文的主要研究工作如下:分析研究车架的边界条件和结构特性,并用壳、管等单元对该车架进行离散,建立一种切实有效的车架有限元模型;对该车架的有限元模型进行模态分析,求得其的固有频率和振型,并对车架的动态特性做出初步评估,分析可能引起车架振动的固有频率;在模态分析基础上,研究发动机输出的简谐力引起的车架位移响应(即谐响应分析) ,以考察摩托车车架各部位的振动情况并与模态分析对比,分析是否与该车架的固有频率相耦合而导致共振;在深入研究车架的模态分析及谐响应分析、清晰地认识了摩托车车架动态特性的基础上,分析并提出了采用橡胶减震器对车架进行隔振的减震方法。
