Tire ground characteristic measuring device, tire ground characteristic measuring system and tire ground characteristic measuring method

摘要

Problem: the resolution in the direction of the rotation axis is not dependent on the size of the sensor.Tire ground characteristic measuring deviceA cylindrical rotating drum rotatable around a rotating shaftDrum drive means for rotating the rotary drum around the rotation axisEmbedded in the cylindrical surface of the rotating drumA first stress measuring means for measuring stress applied to a tire abutting against a cylindrical surface of a rotating drum andThe position where the first stress measuring means is embedded in the cylindrical surface of the rotating drum is embedded at a different position in the rotating circumferential direction of the rotating drum.A second stress measuring means for measuring stress applied to a tire abutting against a cylindrical surface of a rotating drum andStress measured by first stress measuring meansBased on the stress measured by the second stress measuring meansA processing apparatus for calculating tire ground characteristics which is a characteristic in a ground region contacting a rotating drum of tire tread surface andAn output device for outputting the tire ground characteristic calculated by the processing apparatus is provided.Diagram
