摘要
目的对固体火箭发动机全寿命环境载荷情况进行分析,掌握其特性和变化规律。方法在分析固体火箭发动机使用环节主要环境载荷因素基础上,对实测获取的典型固体火箭发动机服役区域的环境载荷数据进行分析。依据固体火箭发动机全寿命服役历程情况,给出全寿命环境载荷的编制方法。结果根据发动机典型服役历程环境载荷特点和服役历程,可以有效掌握发动机全寿命周期内的环境载荷情况。结论该方法具有较好的可操作性,从而为固体火箭发动机结构完整性评价和寿命试验评估提供基础数据。
Objective To analyze environmental load spectrum in total life cycle of solid rocket motor and obtain its characteristics and change rules. Methods Based on the analysis of the main factors of environmental load during the using of solid rocket motor, the typical environmental load data in the service area of the typical solid rocket motor were obtained. On the basis of the service history in the whole life circle of the solid rocket motor, methods for preparing environmental load in the whole life circle were proposed. Results According to environmental load characteristics in typical services of the motor and its service history, the environmental load in the whole life circle of the motor could be obtained. Conclusion The method has good operability. It provides a basis for structural integrity assessment and life prediction of solid rocket motor.
