dc.description.abstractThis paper shows discretized model of main spindle working unit module obtained byANSYS software. Based on the conducted modal analysis for first ten bending modes within frequency range from 0 to 10 kHz,main shapes and natural frequency (eigenfrequency) have been determined,and modal matrix was formed. Obtained results were afterwards used to determinemodel dynamic behavior in the state space using MATLAB. State space model wasfurther used as reference onefor modal reductionwhereby balanced reduction method was applied. Frequency response of full model (all oscillatory modes) and reduced model for direct FRF and cross FRF are presented through Bode diagram. Reliability of the model is verified by comparing the impulse response offull modeland reduced modelin time domain.
