摘　　要：应用相应原理，线粘弹性圆盘和梁的接触问题的解可由相应的弹性圆盘和梁的接触问题的解，经拉氏反变换而得弹性圆盘和梁的接触应力采用Ｃｈｅｂｙｓｈｅｖ多项式展开。Using the corresponding principle,the soultion of linear viscoelastical contact problem between disk and beam can be obtained from the corresponding elastic solution by Laplace inverse transformation.It is convenient for solving the obtained Cauchy integral equation of the contact problem by expending the contact stress into Chebyshev polynomials.An example of contact stress distribution between three-parameter-solid model for disk and simple supported Beam is given.
