Load History Analysis of Solid Rocket Motor Grain On-board
To analyze the load history of solid rocket motor grain on-board and obtain its characteristics and change rules.Based on the analysis of the main load factors in different stages of cooling process after curing,transportation,storage,combat readiness cruise and ignition,the environmental load data obtained from the measurement are analyzed.According to the characteris-tics of engine load during the whole service,the environmental load of the engine can be mastered effectively.By analyzing the envi-ronmental load history of the solid rocket motor in service stage,accurate input conditions and reference data can be provided for the structural integrity analysis and evaluation of the engine,life test and evaluation,and finite element simulation of the engine.
