Abstract
Disclosed are an optima design method for a middle cross beam of an ROPS framework and a cab for engineering machines. The optimal design method comprises: solving a height dimension of a middle cross beam when the maximum bending moment on pillars is minimum by analyzing the influence of the height dimension of the middle cross beam in a portal hyperstatic structural mechanics model on the distribution relation of two bending moments on the pillars, to obtain an optimal height dimension relation of the middle cross beam; and obtaining a profile sectional parameter design relation of the middle cross beam by analyzing a design objective that the middle cross beam and the pillars enter a plastic deformation zone at the same time, and using the relation to guide the selection of an ROPS framework structure and profiles to improve the design quality of an ROPS framework.
