摘要: Abstract The concept of a direct measurement bouncing ball apparatus for the determination traction coefficients lubricants at high pressures and shear rates under impact conditions is outlined. Two basic forms are described, one in which ceramic plate mounted on structure with stiffness normal direction low tangentially, forces being measured by strain gauges, another above piezo-electric transducer capable measuring simultaneously force components. problems encountered dynamic response system severe involved Some preliminary results representative presented.
