The effect is discussed of the rigidity of a scale-pan and the location of load on the natural frequency of a beam-type loadcell scale. First, the modeling procedure is described. The dynamic model can be constructed by combining two vibration models : one is a five-degrees-of-freedom model concerning a part of the scale without the scale-pan, and the other a model concerning the scale-pan itself which is described by applying the equation of bending vibration of an elastic plate. Second, the natural frequencies, f1, f2, f3, which are calculated using the proposed dynamic model are compared with those obtained by experiment. Through this comparison, the adequacy of the proposed model is verified. Consequently, the dependence of f1, f2, f3 on the rigidity of the scale-pan and the location of load is made clear.
