前言以往的车体结构分析方法,几乎局限于垂直载荷作用下的侧墙计算,即一维分析法(应为二维分析法——校注)。而目前,又重新发展了适用于其他主要载荷(水平方向的压缩、拉伸和扭转)情况下的三维的弹性分析理论,并得到了从立体地掌握结构作用到合理化的结构设计的线索,它将有助于随车辆高速化而必然出现的轻型化的研究。一、分析所需的理想结构从客车、棚车的车体来看,是由加强薄板平面结构组成的六面箱体,可以认为是一个半胴体结构(见图1)。这种直的六面体上的加强杆件的配置,可按下述简单地处
Preface The previous method of analyzing the structure of a vehicle body is almost limited to the calculation of the side wall under the action of vertical load, that is, the one-dimensional analysis method (which should be a two-dimensional analysis method - a school note). At present, the three-dimensional elastic analysis theory applied to other main loads (horizontal compression, stretching and torsion) has been re-developed and leads to the structural design from the three-dimensional grasp of the structure to the rationalization of the structural design Will help to speed up the vehicle with the inevitable occurrence of light-weight research. First, the analysis of the ideal structure required From the bus, box car body point of view, is to strengthen the sheet structure of the six-sided box structure, can be considered a semi-carcass structure (see Figure 1). The arrangement of reinforcing rods on such a straight hexahedron can be simply described as follows
