【摘要】 目前,我国某些工矿企业,在缺少用园度仪测量园度误差的情况下,采用三点法(即V形铁法),可以迅速评定园度误差,此方法简便、明睁清晰。 本文,对常用幅值反应系数计算式进行了探讨,对三点法测头示值的福氏级数方程进行了分析;建立了棱园方程与测头示值方程的通式,求出了在不同的V形角时,棱园幅值畸变系数k_n的平均放大倍率K;从而、找出迅速计算园度误差的简便方法。更多还原

【Abstract】 A study of calculating formula of commonly used amplitude-reaction cocfficienf is made in this paper, with the common formula of pviswatic roundnes equation and gauge head indication, equation being established . And the mean amplify-ing times K of prismatic round amplitude distortion-coefficien, Kn is found when in different V-form anhgles. As a rcsn’t, a simples alution method of roundness is obtained.更多还原
