Abstract

Based on the “force standard machine weights exchange method and weights exchange device” patent technology, a deadweight force standard machine (DWM) of 500 kN was developed. Benefited by the weights exchange control system with eight weights and load frame，this machine can load/unload any load level equally with the minimum increment of 10 kN, in 10 kN to 500 kN range，and the load history curve is basically the same. Eliminating the counter-force phenomenon in traditional DWM, it meets the technical requirements of OIML R 60 international recommendations for loading equipment.
