ISO 10767-1에 기초한 유압 펌프의 유량 맥동 측정 및 정밀도 평가

Measurement of Hydraulic Pump Flow Ripple Characteristics Based on the ISO 10767-1 and the Evaluation of the Measuring Accuracy

The source flow ripple and the source impedance in hydraulic pump are characteristic values showing fluid-borne vibration characteristics decisively. We cannot measure these two characteristic values directly, but can measure them by some indirect methods. One representative indirect measuring method is ISO 10767-1. The authors constructed a hardware and a software for the measuring method based on ISO 10767-1. Through the error evaluation of the measured results, accuracy of the measuring method using ISO 10767-1 was examined in detail.
