Achieving the required price indicators when creating new mobile wheeled vehicles becomes possible due to the use of metallurgical products. The objective of this study is to develop technical solutions for a cabin of a mobile wheeled vehicle by using special steel profiles, tubes, sheet material, stampings, and subunits assembled together to form a load-carrying steel frame; and to study the strength of such cabin frame. A welded construction of a load-carrying steel frame of the mobile wheeled vehicle cabin is proposed, consisting of quadrangular tubes and additional rolled steel sheet elements profiled in several directions. An analytical computer model has been developed to study the design of the load-carrying cabin frame by using finite element analysis. To evaluate the strength properties, calculations in accordance with the regulatory requirements of GOST R ISO 5700–2008 and GOST R ISO 3471–2009 were performed. The results of these calculations have shown that the developed load-carrying steel frame of the cabin provides the necessary flail space for the vehicle operator in accordance with the requirements of the regulatory documents.

移动式轮式车舱承载钢架的强度

由于使用冶金产品，在制造新的移动轮式车辆时实现所需的价格指标成为可能。本研究的目的是通过使用特殊钢型材、管材、板材、冲压件和子单元组装在一起形成承载钢框架，为移动轮式车辆的驾驶室开发技术解决方案；并研究这种机舱框架的强度。提出了移动式轮式车辆驾驶室承载钢框架的焊接结构，由四边形管和在多个方向上成型的附加轧制钢板元件组成。已经开发了一个分析计算机模型，通过使用有限元分析来研究承载舱框架的设计。为了评估强度特性，根据 GOST R ISO 5700-2008 和 GOST R ISO 3471-2009 的监管要求进行计算。这些计算的结果表明，根据规范文件的要求，开发的机舱承载钢框架为车辆操作员提供了必要的连枷空间。
