起重机桥架 meaning in English

loading bridge

System of overhead traveling crane parametric design
桥式起重机桥架的参数化设计
It is demanding to fabricate crane bridge as large welded structure , so the upgrade to change its span is very challenging
摘要起重机桥架作为大型焊接结构件，制造要求高，其改制具有典型意义。
The ansys , a kind of fea program , was used to build model of small carriage . the procedure of gantry beam bump with secondary beam of bridge was reappeared by running nonlinear calculation and loading program which was written by apdl program language . the closest deforming result was gotten , and the deforming of main beam , secondary beam and end beam and inner stress distribution status were calculated
采用大型三维有限元软件ansys对该起重机以及小车架等进行了建模、应用apdl语言编写加载程序、进行非线性计算，再现龙门横梁与起重机副梁碰撞过程，最后得到与实际变形结果最接近的一种状态，得出起重机桥架主梁、副梁、端梁的变形以及其内部的应力分布情况。
