An Experimental Comparison Study on Performance Evaluation for the Hydraulic Pin-on-disk Type Tribotester

유압식 마찰시험기의 성능 평가에 관한 실험적 비교 연구

For the purpose of improving accuracy in friction and wear test, a hydraulic pin-on-disk type tribotester was developed and its performance was evaluated experimentally. The performance estimation of the tribotesrer was accomplished by comparing both the consistency of the applied normal load and the robustness of the control against the mechanical disturbances with those of the pneumatic and the dead weight loading method respectively. The developed hydraulic pin-on-disk type tribotester showed the better reliability in the performance and the hydraulic loading method provided the more accurate friction coefficient.
