白车身部分断面结构介绍

1、The integral or unitary body structure of a car can be considered to be made in the form of three box compartments; the middl e and largest compartment stretching between the front and rear road wheel axles provides the passenger space, the extende d front box built over and ahead of the front road

2、wheels enclosing the engine and transmission units and the rear box behind t he axle providing boot space for luggage.整体或综合结构的车身可以被认为由3个车厢组成：中间的最大的一个车厢在前轴和后轴之间，提供乘客空间；前面的车厢在前轮上前方，包括发动机和变速箱单元；后面的车厢在后轴的后面，提供了装行李的空间。These box compartments are constructed in the form of a framework of ties (tensile) and

3、 struts (compressive), pieces(Fig. 1.1 (a & b)made from rolled sheet steel pressed into various shapes such as rectangular, triangular, trapezium, top-hat or a combi nation of these to form closed box thin gauge sections. These sections are designed to resist direct tensile and compressive or bendin

4、g and torsional loads, depending upon the position of the members within the structure.这些车厢由拉伸件和压缩件组成框架结构，这些框架由轧制钢板冲压成各种形状如长方形、三角形、梯形、长桶形或这些形状 的组合形状组成封闭的薄的箱形定型截面。这些截面根据各部件在结构中的位置被设计成用来抵抗直接的拉伸和压缩和弯曲或扭曲力。BC po 球deer 武+82DQubUW th ctoutrieEM nh*4MlFrcrt* sc f reftC&niH od 90,。物祜科 “r wedow WA post 加奸4Sl
