履带式森林消防车沼泽地通过性研究

森林消防车必须具有良好的沼泽地通过性。本文对大兴安岭林区的沼泽地进行了分类，并对３种主战履带式森林消防车（Ｊ－５０、Ａ５３１和ＢＦＣ８０４）的沼泽地通过性进行了理论分析与试验研究，用挂钩牵引力作为通过性评价指标。结果表明，ＢＦＣ８０４可以通过重沼泽地，Ａ５３可以通过中沼泽地，Ｊ－５０只能通过轻沼泽地。森林防火部门应根据管区内沼泽地的特征合理选择消防车。

STUDY ON PASS PERFORMANCE OF FOREST FIRE CRAWLER IN MARSHLAND

Forest fire crawler should have good pass performance in marshland.In the paper.the marshland of Daxing'an forest region was classified into three kinds,and the pass performance of three main kinds of fire crawler(J-50,A531,BFC804) was studied in theory and test.The drawbar pull was used as an evaluation index.The result showd that BFC804 and A531 could pass through deep and medium marshland individually,but J-50 only could pass through shallow one. On the basis of this research, the office of fire prevention could select the type of fire crawler reasonably according to the geographical feature of area.
