摘　　要：低啮合度升压是快开门式压力容器产生爆炸事故的主要原因之一,基于有限元方法,针对一台齿啮式容器,分析了不同啮合度下的力学承载能力。分析结果表明,随着齿面啮合比例降低,结构可承受的极限载荷与疲劳寿命呈下降趋势,且下降速度逐渐加大。Pressuring with low gear meshing ratio is one of the main reasons for the quick actuating pressure vessels explosion produced. Mechanical properties of quick actuating pressure vessels with different gear meshing ratio were analyzed basing on finite element method. The numerical results showed that the ultimate load and fatigue life was gradually decreased with a increasing rate along with the decreasing gear meshing ratio.
