| 摘 要： | 建立了一种测定固体推进剂泊松比的方法－圆管发动机法。测定了两种不同外内径比的圆管发动机药柱在固化降温后内孔的最大向形变量，以该形变量为依据，利用药柱在固化降温过程的有限元计算程序，拟合计算出该配合方药柱在固化降温后于不同温度下的泊松比，测定相对误差均不超过0．5％。

| Abstract: | Cylindrical motors method was built to determine the poisson's ratios of solid propellants.According to the maximum radial deformations of the perforations of cylindrical motors with two different outer-inner radial ratios after having been cured and dropped in the temperatures,the poisson's ratios of the solid propellant grain at the different temperatures was fit out by use of FEM.The relative errors of the poisson's ratios determination at different temperatures don't exceed 0.5%. |
