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:分析研究車架的邊界條件和結構特性,並用殼、管等單元對該車架進行離散,建立一種切實有效的車架有限元模型;對該車架的有限元模型進行模態分析,求得其的固有頻率和振型,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頻率;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頻率相耦合而導致共振;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。This system is based on two altera ’ s statixii series fpga chips ep2s180f1020c5, and the tunner dtt7579 and the chip ad9433, together composed the main hardware platform. the hardware description system running on the fpga is the core of digital down converted sysgtem, synchronization system, estimation and equalization of channel system, 3780 - point fft ofdm demodulation system, frequency equalization system and ldpc decoding
以兩片altera公司的stratixii系列ep2s180f1020c5級聯為基礎構建了系統主硬體處理平臺,結合湯姆遜公司的調諧器dtt7579以及ad9433組成了系統的硬體構架fpga可描述硬體系統的核心任務包括數字下變頻,同步和通道均衡與估計, 3780點fftofdm解調,頻域均衡, ldpc解碼。It is shown by the two - stories frame model shake - table test that the contrast two response of acceleration based on wavelet and experiment draws on such conclusion : littlewood - paley wavelet does not agree with the test, so it is not suitable for structural seismic response, because structural acceleration response is too small. the wavelet transform result of acceleration response based on meyer wavelet, harmonic wavelet and odd exponent wavelet agree with the test, thus they can be used to analyze structural seismic response. the analysis of earthquake ground motion energy and structural energy response based on these three wavelets ( littlewood - paley wavelet, meyer wavelet, harmonic wavelet ) shows that we can calculate earthquake ground motion energy by the record of acceleration, because the wavelet coefficient includes time - domain energy and frequency - domain energy
通過對二層框架模型進行振動臺試驗研究說明:從小波變換得到的加速度反應和模型上的第一層及第二層的試驗測得的加速度比較得出的結論是, littlewood ? paley小波不適合於用來作結構地震反應分析,因為在此小波下的結構加速度反應太小,和實驗情況不符; meyer小波、諧波小波、單邊指數小波這三種小波從理論上得到的加速度反應同實驗測得的加速度過程比較吻合,因此從試驗上證明用meyer小波、諧波小波和單邊指數小波來作結構地震反應分析是比較合適的。
