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, f_1,f_2,f_3, 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 f_1,f_2,f_3 on the rigidity of the scale-pan and the location of load is made clear.
