| Abstract: | This paper gives a general equation for the ideal curve of crane beam with joint support,then further discusses the effect of elastic support on the curve, and gives the complement equation. In the end the paper employs examples to prcsent the operation method for the general equation,and introduces the method to cope with the effect of the elastic support. |
