IMPROVEMENT OF THE RELIZATION OF 500 KN FORCE BY DEADWEIGHT FORCE MACHINE AT NIMT

摘要

A 500 kN Deadweight force standard machine (DWM) was originally installed at Rama IV, Bangkok. In 2005, the DWM was moved to the new location at the Technopolist, Pathumthani. Due to some factors that could affect the force generation of the system, many parts of the machine needed to be modified and recalibrated. This paper presents the comparison results of the DWM between before and after modification, using two loadcells as the artefacts to compare in term of repeatability, reproducibility and linearity of the system.
