진동감쇄
성능평가 시스템
안전보호 제품의 진동감쇄 성능에 대한 물성평가를 위한 시스템으로,
역학적 충격 대응 안전보호 제품의 성능을 종합적으로 평가하기 위한 시스템

Experimental setup: (A) force plate; (B)applied feed force display; (C) remote-controlled riveting hammer; (D) energy absorber; (E) simulated rivet; (F) bucking bar pressed against the simulated rivet.
Tri-axial acceleration data were simultaneously collected at the riveting hammer, the bucking bar, and at the right wrist of the bucking bar operator.
