Conclusions
-
1.
In order to raise the operating speed of spring weighing devices and reduce their dynamic errors it is necessary to raise the angular frequency of their natural oscillations and produce a moving system with a minimum weight and its natural oscillations damping factor equal to the angular frequency of these oscillations (λ=ω 0).
-
2.
The natural oscillation frequency of a spring weighing mechanism which has n elastic elements is √1/n times lower when the elements are connected in series, and it is √n times higher when they are connected in parallel as compared with the frequency of a similar mechanism with a single element.
