摘　　要：对轮胎设计的有限元计算中关于泊松比的应用提出了新的见解，认为应该把泊松比计算式中的横向应变改成帘线横截面变化率较为妥当。介绍了用“截面固结法”测定钢丝帘线横截面变化率的实验方法。A new viewpoint on the application of poisson′s ratio to the finite element calculation in tire design has been proposed.It is considered that the transverse strain of steel cord in the typical formula should be replaced by the section variation ratio,and an experimental method to measure this ratio is put forward as well.
