Abstract

본 발명은 디스크 브레이크 장치에 구비된 디스크가 바퀴와 함께 회전하면서 그리는 기하학적인 형상을 측정하는 것이다.The present invention is to measure the geometrical shape that the disk provided in the disk brake device while rotating with the wheel.

본 발명은 디스크의 내측 및 외측 변위 변화량과 내측 및 외측의 원주 방향 두께를 정밀하게 측정하고, 측정한 디스크의 내측 및 외측의 원주 방향 두께 차이가 그리는 기하학적 형상을 주파수로 분석하는 것으로서 브레이크 장치의 내구성 시험에 사용되는 다이나모 메터 상에 디스크의 내측 및 외측 변위 변화량을 검출하는 변위 센서를 설치함과 아울러 디스크의 1회전을 검출하기 위한 광 센서를 설치하며, 디스크가 1회전하는 동안 변위 센서가 검출한 디스크의 내측 및 외측 변위 변화량을 카운터로 카운트하고, 데이터 수집부에서 수집하여 컴퓨터 시스템에 입력시키며, 컴퓨터 시스템은 수집된 디스크의 내측 및 외측 변위 변화량의 측정값 및 두께를 표시하고, 두께 차이가 그리는 디스크의 기하학적 형상을 주파수 분석하여 표시한다.The present invention precisely measures the inner and outer displacement variation of the disk and the circumferential thickness of the inner and outer sides, and analyzes the geometrical shape of the difference in the measured circumferential thicknesses of the inner and outer circumferential thicknesses of the disk by frequency. On the dynamometer used for the test, a displacement sensor for detecting the inner and outer displacement variation of the disk is installed, and an optical sensor for detecting one rotation of the disk is installed. The inner and outer displacement variation of the disk is counted by a counter, collected by the data collector and input into the computer system, and the computer system displays the measured value and thickness of the collected inner and outer displacement variation of the collected disk, and draws the thickness difference. The geometry of the disc is displayed by frequency analysis.
