INFLUENCE OF AERODYNAMIC EFFECTS IN DEADWEIGHT MACHINES

摘要

In the evaluation of uncertainty of the forces generated by deadweight force standard machines, several contribution should be taken into the account. One of them, that normally is considered negligible, is the influence of aerodynamic effects. In the paper the theoretical analysis of this effect and the experimental measurements made on the INRIM deadweight FSM Galdabini 1 MN are presented.
