freely supported meaning in English
简支的
自由支承的
Examples
- The mathematic model of the ultra - thin spherical mirror is to be treated as elastic thin shell . then the predigested model , i . e . , bended beam , used in qualitative analysis was proposed , and its deflection and stress formulas under the freely supported condition were set up . based on an off - axis aspherical primary mirror , the relationship of aspherical surface error ( rms ) in tangential plane with bended beam ’ s radius r , position s of concentrated load p and geometry length l of arc was analyzed
根据这一设想,本文建立了超薄镜的数学模型?薄壳,并提出了强制力作用下超薄镜的简化模型?曲梁,推导了曲梁在简支情况下受力变形的挠度公式,并结合一个实例,计算出曲梁变形后与所需非球面的面形残差( rms )在子午方向与曲梁弧长l 、曲梁半径r及集中力位置s的关系及满足面形精度的r和s范围,分析了弧矢方向的rms ,得出了同时满足子午和弧矢方向面形要求的l 、 r和p 。 - However , the pre - stressed anchor cables on the upper part of the piles make the whole stabilizing system like freely supported beams or some other h yperstatic structures . with the number of restraints increasing , it makes much easier to control the displacement of the piles and to reduce the bending moments and shearing forces along the piles to a certain extent
增加预应力锚索后，整个结构体系接近简支梁或其它超静定结构，随着约束的增加桩身的位移控制变得容易许多，同时桩身内力值也在一定程度上减少较多。
