大型推土机翻车和落物保护结构受力研究

Analysis for roll-over and falling-object protective structure of large bulldozer

以TY320推土机为例,在国际标准ISO3471:1994实验室静态试验方法基础上,分析了翻车和落物保护结构的变形过程,进一步对翻车和落物保护结构进行了非线性有限元计算,模型试验及计算结果吻合,表明计算方法是可行的。

The paper takes TY320 as an example to analyze the process of transform based on the laboratory static states of the international standard ISO 3471:1994. And t he further nonlinear finite element calculation is done to analyse the protectiv e structure as well as safety place for a driver to stay in.
