摘要/Abstract

摘要： 为了提高航天复合材料压力容器的性能因子,根据复合材料压力容器网络理论方法提出了“参数对应关系”结构设计方法,对一种卫星推进分系统复合材料氦气瓶进行了结构设计,确定了纤维复合层承载压力,得到了不同内衬壁厚情况下气瓶纤维预紧应力与内衬压缩应力、内衬工作应力、纤维工作应力的对应关系,获得了内衬最小壁厚和纤维预紧应力区间等参数,用有限元法对气瓶结构设计进行静力学分析校核,所设计气瓶完成了全部的鉴定试验,气瓶性能因子37km,爆破压力70MPa,纤维预紧应力区间为[120MPa,270MPa]。设计和验证结果表明:基于网络理论的 “参数对应关系”结构设计方法可用于弹性工作金属内衬复合气瓶的研制,内衬最小壁厚的精确求解对提高复合材料气瓶性能因子是有效的。 

Abstract: In order to increase the performance factor of composite pressure vessel, a Parameter Correspondence Relationship structure design method was put forward for composite pressure vessel in terms of grid theory. The structure design of composite pressure vessel for the propulsion system of some satellites was performed, and the load pressure of composite was calculated.The relationship between auto-frettage fiber stress and liner compressive stress, liner working stress and fiber working stress was calculated in different liner thickness,while the liner minimum thickness and auto-frettage fiber stress region was calculated. The statics of the designed vessel were collated by finite element method, and the completed qualification tests were completd.The performance factor of vessel is 37kilometers and the burst pressure is 70MPa and auto-frettage fiber stress region is [120MPa,270MPa]. The results of the design and validation show that the composite pressure vessel design based on parameter correspondence relationship structure design method is feasible and the liner minimum thickness is effective to increase the performance factor of composite vessel. 
