1 引 言 森林火灾是当今世界森林的四大灾害之首,对森林的破坏相当严重,因此,开展森林防火、灭火技术的研究是十分必要的。而作为森林灭火主要装备的森林消防车,其更新换代与提高性能是当前迫切需要解决的问题之一。目前,我国的森林消防车基本是用履带式或轮式越野车辆改制的。履带式森林消防车虽具有很好的通过性能,可接近火场灭火,但存在
1 INTRODUCTION Forest fires are the first of four major disasters in the world’s forests and the damage to forests is very serious. Therefore, it is necessary to carry out the research on forest fire prevention and fire extinguishing technologies. As a major forest fire fighting equipment, forest fire engines, its replacement and improve performance is one of the urgent problems to be solved. At present, the forest fire trucks in our country are mostly rebuilt by crawler or wheeled off-road vehicles. Although tracked forest fire engines have good performance through the fire near the fire, but there
