摘　　要：针对复合固体推进剂基体的大变形和界面的脱粘问题,对Mori-Tanaka法进行了改进。同时,为验证该方法的有效性,针对推进剂颗粒随机填充的特点,提出了一种含非线性界面脱粘的数值方法。最后以某推进剂配方为算例,对2种方法的计算结果进行了比较。结果表明,2种方法结果接近,从而验证了改进的Mori-Tanaka法的有效性,且改进的Mori-Tanaka法计算量小,极大地提高了计算效率。Aiming at the problems concerning the composite solid propellant with large deformation in the matrix and interface debonding around the filled particles,an improved Mori-Tanaka method was developed.At the same time,in order to verify its effectiveness,a simulation method for the interface debonding of the composite solid propellant consists of random filled particles was also put forward.Finally,a computational case of one kind of composite solid propellant was investigated.It is demonstrated that the results from these two methods are close and the improved Mori-Tanaka method is effective;the computational time can be reduced dramatically and the computational effectiveness can be increased greatly by using the improved Mori-Tanaka method.
