Improvement of the Realization of Forces between 2 Mn and 5 Mn at Ptb – the New 5 Mn Force Standard Machine
− Since November 2008, PTB's force scale has been complemented in the range from 2 to 5 MN by a further force standard machine. This automatically working 5 MN Force Standard Machine (FSM) utilizes the hydraulic amplification of a 50 kN mass stack and enables low uncertainties of smaller than 0.01% by using innovative methods for the control principle and the link-up of the force standard. In t...

متن کاملEVALUATION OF STATIC AND DYNAMIC PARASSITIC COMPONENTS ON THE INRIM 1 MN PRIMARY FORCE STANDARD MACHINE BY MEANS THE 500 kN SIX-COMPONENT DYNAMOMETER
A recent improvement on the ancillary instrumentation and on the acquisition software of the 100 kN and 500 kN INRIM six-component dynamometers makes it possible to measure the parasitic components at static conditions and during the weight transition too, in order to weigh up the influence of the dynamic phenomena on the value of axial load. This paper presents the main results of the evaluati...

Evaluation of force generation mechanisms in natural, passive hydraulic actuators
Pine cones are well known natural actuators that can move their scales upon humidity gradient. The mechanism manifests itself through a displacement easily observable by the naked eye, but coupled with stress generation. In ancient Egypt, wooden wedges were used to break soft blocks of stone by the generated swelling stress. The purpose of the present study is to evaluate the ability of pine co...
