【摘要】 利用有效导纳复功率流法研究了无限平板线激励下的功率传递规律,得出了线激励下的有效线导纳的理论公式,并对有效线导纳的功率传递特性进行了仿真研究。比较了有效线导纳理论公式和数值估计公式的计算结果,得到了数值估计公式的适用范围。然后研究了梁线激励作用下的功率传递特,并且对平板和梁上的功率传递规律进行了比较,结果为平板线激励的相对传递功率要略大于梁的相对传递功率。表明有效线导纳的理论公式在研究结构的功率传递上的灵活性和适用性。更多还原

【Abstract】 The rule of power flow transmission with line force acting at an infinite plate is examined by effective mobility power flow method, and the theoretical formula of effective line mobility is given. Simulation is carried out to illuminate the power flow transmission property of effective line mobility. By comparing theoretical results with those calculated by numerical evaluation formula, suitable range of numerical evaluation formula is present. At last, power flow transmission law of a beam under line exciting is investigated, which is compared with that of an infinite plate under line exciting and displayed a little more power flow transferred in a plate than in a beam. Study shows much flexible and more validity by using of theoretical formula of effective line mobility in studying the power flow transmission between structures.更多还原
