摘　　要：起动箱是保证液氧/煤油发动机可靠起动的重要组件。针对起动箱结构特点,采用胶囊材料Mooney-Revlin本构关系,建立起动箱三维模型,分析起动箱动作特性。仿真结果再现了起动箱工作过程,获得胶囊翻转压力为58 kPa。抽真空试验和计算表明,胶囊压力为50~60kPa时起动箱胶囊可自动复位,仿真结果与试验结果基本吻合。The starting box is an important component for the stable and reliable starting of LOX/kerosene rocket engine. The operational characteristics of the starting box are analyzed by Mooney-Revlin model of bladder material and 3D model of the starting box. The operational process of the starting box was reoccurred by means of simulation result. The reversing pressure （58 kPa） of the rubber bladder was obtained. The vacuum test and calculation show that the bladder will return to its original position automatically under the pressure with the measured ones. of 50-60 kPa. The predicted values are agree
