Analysis of the Vibration Characteristics of a Boring Bar with a Variable Stiffness Dynamic Vibration Absorber

Table 1

Parameters of the boring bar with a variable stiffness DVA.

	Equivalent stiffness of the boring bar, (N/mm)	Equivalent mass of the boring bar, (kg)	Natural frequency of the boring bar, (Hz)	Time period, (s)	Damping coefficient of the boring bar, (N·s/m)	Equivalent mass of the DVA, (kg)	Damping coefficient of the DVA, (N·s/m)
Boring bar with a DVA	2496.6	0.8764	268.62	0.02339	9.98	0.9126	249.92
Regular boring bar without a DVA	2563.2	1.2757	225.60	0.02785	9.99	—	—
