EFFECT OF A SCALED CANTILEVER BEAM ON NATURAL FREQUENCY

This paper deals with the scaling factor's effect on cantilever beam's natural frequency. Scaling a prototype dimension will make it easier to manufacture and test dynamic characteristics of structures enormous sizes. Natural frequency is one essential parameters vibration system. The phenomenon that often occurs in vibrating resonance phenomenon. Resonance system state which an abnormally large generated response external stimulus, happening when disturbance equal to, or nearly identical research investigates scale factor using analytical method Euler-Bernoulli beam theory, MSC Nastran/Patran software, experimental testing impact hammer beam. three methods were applied beams four variations: 1:1, 1:2.04, 1:2.85, 1:3.48. Based results, frequencies increase by size reduction value modeling. actual structure has equivalent 1/S scale, whereas S defined as downgrade value. result follows Similitude theory.
