- Abstract:
- Dynamic strain measuring technique in the liquid rocket engine tests is introduced in this paper. The principle of dynamic strain measuring is introduced firstly and the influence of long cable on the sensitivity of strain sheet is analyzed. The bonding technology of strain sheet is also introduced and the interference signal of the dynamic strain measuring system is analyzed. The influence of temperature on the dynamic strain measuring system and its improving method is also analyzed in the paper.
