摘　　要：对一类特定网格结构模型的粘弹性问题做了解答.在弹性网格结构模型的基础上提出的粘弹性网络结构模型,与实际结构更为接近;该模型具有其对应的弹性模型的特点,即形式简单,控制方程组合简便,易于在计算机上实现运算.In this paper, a solution is given to a special kind of viscoelastic lattice structure model. This kind of viscoelastic model based on the elastic lattice structure model is more close to practical structure, and has the characteristics of corresponding elastic model, i.e. simple form, convenient combination of control equation and easy calculation in computer.One finite element analysis method obtained from this model of viscoelastic lattice structure can provided an idea for fully utilizing existing software and developing new viscoelastic finite element computation software.
