为了测量摩擦力和弹簧力之间的力平衡中动摩擦系数的真实值，开发了抗振动摩擦计（AVT）。 AVT利用一种新颖的原理，即两个速度（即一个接触表面的驱动速度和另一个表面的移动速度）之间的角度偏差产生正阻尼效应，以稳定平衡点并自主抑制摩擦振动。例如，当钢球和钢板之间的滑动接触用甘油润滑时，AVT在错位角φ=30°（即抗振动设置）处提供力平衡情况，尽管在φ=0°（即传统设置）时发生强烈的摩擦振动。通过比较 φ = 0° 和 30° 时获得的动摩擦系数，发现摩擦振动会导致动摩擦系数测量出现严重误差（例如，低行驶速度时低估 35%）。
To measure true values of kinetic friction coefficient in a force balance between the frictional force and spring force, an anti-vibration tribometer (AVT) has been developed. The AVT utilizes a novel principle that an angular misalignment between the two velocities (i.e., the driving velocity of one of contact surfaces and the moving velocity of the other surface) produces a positive damping effect to stabilize the equilibrium point and suppress frictional vibration autonomously. For example, when a sliding contact between a steel ball and a steel plate is lubricated by glycerin, the AVT provides a force balance situation at a misalignment angle φ = 30° (i.e., an anti-vibration setting), although strong frictional vibration occurs at φ = 0° (i.e., a conventional setting). By comparing the kinetic friction coefficients obtained at φ = 0° and 30°, it has been found that frictional vibration can lead to a serious error of measuring kinetic friction coefficient (e.g., a 35% underestimation at a low driving speed).
