四边简支矩形薄板集中力作用中心弯矩影响面

The central bending moment influence surface of the concentrated force of the rectangular thin plate

根据弹性力学的相关理论,对四边简支矩形薄板的弯矩解答进行了分析,从影响面方面进行了论述,提出了在集中荷载作用下的四边简支矩形薄板的中心弯矩影响面的概念,并对其进行了研究,研究表明,四边简支矩形薄板的中心弯矩影响面在解决最不利荷载位置方面达到了很好的应用效果,最后进行了实例验证。

According to the related theory on elastic mechanics,the thesis makes analysis to the bending moment solution of the rectangular thin plate,discusses the influence surface and proposes the concept of central bending moment influence surface of the rectangular thin plate under the concentrated load.The study indicates that,the central bending moment influence surface of the rectangular thin plate has effect on resolving the unfavorable load position,which is exemplified by the practices.
