| 摘 要： | 采用Timoshenko梁修正理论研究了泡沫金属铝合金梁的动力响应问题。应用Timoshenko梁修正理论建立了泡沫金属铝合金梁的振动方程，求得了其自振频率表达式及其在简谐荷载作用下强迫振动的解析解。通过实例计算，把球形泡沫铝合金梁与其它泡沫铝合金梁进行了对比分析，得出了球形泡沫金属铝合金梁的动力性能优于其它泡沫铝合金梁的动力性能。

| Abstract: | The dynamic response of a foam metal aluminum alloy beam was studied with Timoshenko beam theory. Its vibration equation was established with Timoshenko beam theory,the expression of its natural frequency and the analytical solution of its forced vibration under the action of harmonic load were obtained.The comparative analysis of a spherical foam aluminum alloy beam and the another foam aluminum alloy ones was carried out with practical calculation. It was summarized that the spherical foam metal aluminum ... |
