Title:
すべり抵抗係数測定装置
Document Type and Number:
Japanese Patent JP7142460
Kind Code:
B2
Abstract:
To provide a sliding resistance coefficient measuring apparatus that can accurately and easily measure the sliding resistance coefficient of a road surface with no need for complex structure.SOLUTION: A sliding resistance coefficient measuring apparatus (100) of the present invention comprises: a measuring disk (17); a road surface sliding resistance measuring rubberized piece (30, 50) mounted on the measuring disk (17); a velocity measuring device (7: encoder); and a controller (control unit CU: control circuit board). The controller (CU) has a function of computing a sliding resistance coefficient (μ) based on deceleration (β) when the road surface sliding resistance measuring rubberized piece (30, 50) touches a road surface.SELECTED DRAWING: Figure 1
