摘要
依照最小二乘法原理,提出了由试验数据拟合出推进剂松弛模量主曲线及W.L.F.方程中参数的方法,建立了统一的松弛模量主曲线拟合模型。讨论了QJ2487 93《复合固体推进剂单向拉伸应力松弛模量及主曲线测定方法》标准中所提出的方法,对有关方法进行了对比。文中提出的方法有待于在进一步应用中检验。
Based on the least square method, a fitting method of solid propellant relaxation modulus master curve and parameter of W.L.F. equation by using test data is put forward. A uniform fitting model is set up. The paper also discusses the method given in standard QJ 248793'Test method of composite solid propellant stress relaxation modulus and master curve using unilateral tension' and compares it with correlative methods. This method has yet to be confirmed in further application.
