Impact of force application point in two-mass oscillation system on its energy efficiency

Introduction . The goal is to perform a comparative analysis of energy consumption during the operation resonant two–mass mechanical system, depending on point application driving force first or second mass. object research an oscillatory system vibrating machine consisting two masses interconnected by elastic and dissipative elements. In addition, mass connected fixed base through Materials methods uses main provisions theoretical mechanics, mathematical modeling simulation experiment in Matlab-Simulink environment. Results According results model two-mass with mass, it was found that 10 kN frequency 80 rad/s, amplitude oscillations 0,6 mm, 1,8 while gain 3,94. To achieve specified force, directional debalance exciter kg debalances must have eccentricity 0,16 m, power required drive oscillation 21,2 kW. case applying possible same (0,6 mm) 5 kN, 0,078 m 4,9 kW, 8,44. Originality Thus, due dynamic properties option 4,3 times more efficient than
