体积松弛模量与体积蠕变柔量的研究

Study on the Volume Relaxation Modulus

简述了体积松弛模量Ｋ（ｔ）与体积蠕变柔量Ｂ（ｔ）之问的精确与近似转换关系，提出一种根据实测Ｂ（ｔ）诊断Ｋ（ｔ）的数值积分算法。通过体积蠕变实验给出一种下羟固体推进剂的Ｂ（ｔ）和Ｋ（ｔ）的实测与转换计算结果。

he exact and approximate inversion relationships between volume relaxation modulus K (t) and volume creep compliance R (t) are summarized.A numerical integration algorithm for solving K (t) from expermetal B (t) is presented.The experimental and calculated results of D (t) and K (t) are gi on for a HTPBsolid propellant on the basis of the volume creep experiments.
