摘要:
为了研究固体推进剂的粘弹性力学行为,该文在遗传积分形式的粘弹性泊松比表达式基础上,结合拉普拉斯变换和蠕变试验条件,推导出推进剂材料在已知横向应变和松弛模量时的泊松比精确表达式,并利用Matlab编制相应的计算程序。设计相应的蠕变试验获得推进剂材料的横向应变,结合推进剂材料的松弛模量获得材料的泊松比与时间的变化规律。该文结果可为固体推进剂装药结构完整性分析提供输入参数。
Abstract:
In order to study the viscoelastic behavior of solid propellants,based on the hereditary integral forms of the viscoelastic Poisson's ratio expression and combined with the Laplace transformation and creep test conditions,the accurate Poisson's ratio expression of the propellant material is deduced with the known transverse strain and relaxation modulus,and the corresponding program is compiled by Matlab.The corresponding creep test is designed to obtain the transverse strain of propellant materials.The change law between the Poisson's ratio and time of the propellant material is obtained based on the relaxation modulus.The results can provide input parameters for the structural integrity analysis of solid propellants.
