推土机翻车和落物保护结构侧向受力研究

Research on lateral force on roll-over and falling-object protective structures for bulldozer

简要介绍了ISO国际标准对推土机翻车和落物保护结构的评价指标,并分析在侧向载荷下,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,模型试验与计算结果吻合,表明计算方法是可行的。

It introduces the evaluation indexes from the international standard concerning the roll- over and falling- object protective structures for bulldozer and discusses how the structures deform under acting lateral force. Through nonlinear finite dement calculation and model test it comes to conclusion that the calculation method is feasible .
