摘　　要：给出了求解刚性滚筒以给定速度滚过粘弹性基础问题的计算公式。利用Winkler粘弹性基础假设简化问题模型,并以标准线性固体模型描述粘弹性材料的本构关系,从而得出粘弹性基础接触区域的应力分布函数。最后的算例表明了运用该公式求解刚性滚筒与粘弹性基础接触问题的有效性。A calculation formula is developed to solve the problem of a rigid cylinder while rolling over a viscoelastic foundation at any given speed.By adopting Winkler viscoelastic foundation assumption to simplify the problem model,and by using a standard linear solid model to describe the constitutive relationship of the viscoelastic material,the stress distribution function at the contact area of the viscoelastic foundation was obtained.The final example shows it is effective to use this formula to solve the contact problem of the rigid cylinder with the viscoelastic foundation.
