|
Abstract:
针对行波式能量吸收装置，其能量吸收效率受多种因素影响。为优化其性能，本研究对单个行波板进行了建模与仿真分析。运用响应面法，以无量纲波幅、无量纲波速及波数为变量，能量吸收效率为响应目标，进行了参数优化设计。结果显示，各因素对能量吸收效率的影响程度依次为：无量纲波幅、无量纲波速、波数。经过响应面优化，得到最优参数组合为无量纲波幅0.111、无量纲波速0.601、波数4.518，此时能量吸收效率可达84.27%。为进一步验证优化参数的有效性，进行了数值模拟对比，结果显示响应面预测值与数值计算值之间的误差仅为0.821%，从而验证了响应面模型在行波式能量吸收装置优化设计中的有效性。
For the traveling wave energy absorption device, there are many factors that affect its energy absorption efficiency. To optimize its performance, this study conducted modeling and simulation analysis on a single traveling wave plate. Using the response surface method, the dimensionless wave amplitude, dimensionless wave speed, and wave number were studied as variables, with energy absorption efficiency as the response target for parameter optimization design. The results showed that the impact of each factor on energy absorption efficiency was ranked as follows: dimensionless wave amplitude, dimensionless wave speed, and wave number. After response surface optimization, the optimal parameter combination was obtained with a dimensionless wave amplitude of 0.111, a dimensionless wave speed of 0.601, and a wave number of 4.518, at which point the energy absorption efficiency could reach 84.27%. To further verify the validity of the optimized parameters, a numerical simulation comparison was conducted, which showed that the error between the predicted value of the response surface and the numerical calculation value was only 0.821%, thus verifying the effectiveness of the response surface model in the optimization design of the traveling wave energy absorption device.
