    摘要採用有元和邊元方法建立了輕流體介質中復雜結構振動聲輻射的模態分析模型,可計算結構的聲輻射模態、模態場點聲壓、模態輻射聲功和聲輻射聲場特性參數。
  2. 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

    論文的主要研究工作如下:分析研究車架的邊條件和結構特性,並用殼、管單元對該車架進行離散,建立一種切實有的車架有元模型;對該車架的有元模型進行模態分析,求得其的固有和振型,並對車架的動態特性做出初步評估,分析可能引起車架振動的固有;在模態分析基礎上,研究發動機輸出的簡諧力引起的車架位移響應(即諧響應分析) ,以考察摩托車車架各部位的振動情況並與模態分析對比,分析是否與該車架的固有相耦合而導致共振;在深入研究車架的模態分析及諧響應分析、清晰地認識了摩托車車架動態特性的基礎上,分析並提出了採用橡膠減震器對車架進行隔振的減震方法。
