Optical interferometer system for shape monitoring of large high-aperture mirrors using the null method
Engineering Education # 11, November 2013 DOI: 10.7463/1113.0654983 It was proposed to carry out performance evaluation of active vibration damping in multi-mass dynamic systems of metal structures of excavators and jib cranes when damper’s power body is located between oscillating masses, in comparison with external resistance damping. Results of synthesis of damping effect which provides a specified degree of oscillation decline in metal structures under force excitations and self-oscillations were presented. It was shown that allocation of the active damper’s power body between the working body’s installation unit and metal structures of machines allowed one to improve dynamic properties of the specified machines significantly.
