摘要
利用Ｂｅｒｇｅｒ和Ｇａｌｅｒｋｉｎ近似法，导出了在连续激光与横向力联合作用下固支国薄板的轴对称大挠度ｗ的表达式。针对空间均匀和高斯型分布的激光束辐照，采用理论和有限元法计算，给出了板中心挠度ｗｃ随辐照时间及横向力的变化，讨论了板中温度矩、温度膜力和材料参数的温度相关性对挠度的影响及温度场与横载联合对圆板大挠度的作用机制。
The action mechanism of both laser-induced temperature rise and lateral force on the largedeflections of a clamped circular plate subjected to combined CW laser and lateral force is analyzed and the results indicate that the gradient effects of thermo-softening and the temperature moment are of quite importance. The theoretical and FEM results are in quantitatively accordance with each other and also in qualitatively agreement with pertinent theoretical and experimental ones in references.
