Apparatus for measuring noise from a tire on the road

摘要

PURPOSE: An apparatus for measuring a noise of a tire is provided to reduce the cost and time required for development by testing the tire under conditions similar to an actual car conditions, and improve the reliability of data related to the noise of the tire. CONSTITUTION: An apparatus for measuring a noise of a tire(100) includes a road roller driving body(20) manufactured similar to conditions of a road, a tire fixing body(10) installed to adhere the tire to a surface of the road roller driving body to be rotated, a detecting element(30) detecting a noise generated from the tire, and an air pressure control unit(40) controlling air pressure of the tire, wherein the road roller driving body includes a chassis dynamo(21), a driving motor(22) driving the chassis dynamo, and a controller(23) controlling rotary moving velocity of the chassis dynamo; and the detecting element includes a micro phone(31) detecting the noise at a part where the tire and the road roller driving body contact with each other, and a display(32) displaying a signal detected from the micro phone.
