一、横梁的设计与选择横梁也叫做导板梁,是支承和固定导卫装置用的,其形状有很多种。这时的矩形梁及不常用的形状不谈,现仅介绍一下常用的断面形状,如图1所示。横梁主要尺寸(如图2)的确定决定于受力情况。根据理论计算 First, the design and selection of beams Cross beams, also known as the guide beam, is used to support and fixed guide guard, and its shape has many kinds. At this moment of rectangular beam and not commonly used shapes aside, now only introduce the commonly used cross-sectional shape, as shown in Figure 1. The main beam size (Figure 2) is determined by the force situation. According to the theory calculation
