Popis: Radiator and engine, the major components of the generator are mounted on the base frame with the help of mounting brackets. These brackets are subjected to vibration during the working of the generator. Noise related problems that occur in mechanical structures are mostly due to vibrations. Excessive vibration results in structural damage. The structure itself has certain internal properties and it is important to understand its characteristics. This paper focuses on the derivation of transfer function of radiator brackets to express their dynamic vibration characteristics. The approach to derive the same comprises of finite element modelling of the radiator bracket, model validation, parameter identification based on sensitivity study and design of experiments to derive the transfer function. In this paper, transfer function for the first two bending frequencies of the bracket is developed with parameters that would significantly affect the fundamental frequency as inputs. The first two bending frequencies obtained from analytical method are compared with that from the finite element models and found to have good agreement. The transfer function developed will avoid expensive testing and time consuming simulations. It will also form a base to develop a more robust design.
