APPARATUS FOR MEASURING NATURAL VIBRATION MODE AND VIBRATION TRANSFERRING CHARACTERISTIC OF TIRE

摘要

PURPOSE: An apparatus is provided to conveniently and easily measure a natural vibration mode and a vibration transferring characteristic of a tire by measuring the natural vibration mode and vibration transferring characteristic of the tire without installing the tire in a vehicle. CONSTITUTION: A natural vibration mode measuring apparatus includes a supporting frame(60) formed at an inner upper portion thereof with a guide slot(63) and having a plurality of supporting shafts. A lower plate(10) is installed at an inner lower end of the supporting frame(60). A vibrator(11) having a stinger(12) at an upper portion thereof is mounted on the lower plate(10). A fixing plate(20) is installed in the supporting frame(60) and formed at a center thereof with a stinger hole(21) for mounting the tire(40) on the fixing plate(20). An upper plate(30) is installed in the supporting frame(60). The upper plate(30) includes a vibration transferring shaft(32), a weight(31), and an accelerometer(50).
