TIRE PROPERTY TESTING DEVICE FOR TESTING PROPERTIES AND DYNAMIC GROUND CONTACT PRESSURE PROPERTIES OF A TIRE

摘要

PURPOSE: A tire property testing device is provided to install all components necessary for a test inside a single housing unit, thereby testing a tire.;CONSTITUTION: A tire property testing device includes a housing unit (1), a transparent grounding plate (2), a three-axis load cell (3), a photographing member (4), a driving member (5), an angle adjusting member (6), a movement measuring member (22), and a computer (7). The transparent grounding plate is installed at the entrance of the housing unit and becomes in contact with a tire. The three-axis load cell installed on the bottom surface of the transparent grounding plate measures the forces actuating on each direction of x, y, and z axes which are generated on the tire. The photographing member photographs the grounded plane of the tire in contact with the transparent grounding plate. The driving member rotates the tire. The angle adjusting member adjusts the horizontal and vertical angles formed by the tire and the transparent grounding plate. The movement measuring member measures the movement when the transparent plate is moved back and forth, and left and right sides after being grounded. The computer includes a program calculating the dynamic ground contact pressure, a grounded shape, and the deformation of the tire based on the signals sensed by the three-axis load cell and the photographing member.;COPYRIGHT KIPO 2013;[Reference numerals] (AA) Temperature control; (BB) Humidity control; (CC) Horizontal steering; (DD) Vertical steering
