振动平衡
1.A rapid linear motion of a particle or of an elastic solid about an equilibrium position.
2.Principle and Application of the Additional Weight Balance of Micro-amplitude Mechanism Driven by a Crank Gear
3.According to the experimental results of absolute test and on-line test,the ultra low frequency vibration table is substituted with the SCM for FBA dynamic test.
4.This paper presents the basic construction and movement rules of the coordinator gyrorotor with reticle of Archimedes spiral reticule pattern, Also, it explains the principles and methods of dynamical balance to damp the vibration and forced nutation.
5.Based on brief introducing the Coulomb damping mechanism,by having analyzed on Coulomb damping ideal model and linearity double hysteretic systems resilience,by having used humorous wave equity of nonlinear vibration theory and FFT,it studies the double linear hysteretic vibration reduction systems which include displacement thrice nonlinear viscous damping.
6.Nonlinear Finite Element Method for Equilibrium and Natural Frequencies of Cable Structures
7.During a part of each oscillation, a region whose pressure is above the equilibrium pressure is formed.
8.The vibration of single cylinder and multi-cylinder engine is the main research, which is caused by the unbalance force and moment.
9.The object for this study is the rotor-support system of a bigger transmission power aeroengine with engaged action of central bevel gears and Square Film Damper(SFD), critical speed and natural frequency of transverse vibration and static unbalance response and intial bending response are computed by using the transfer matrixes of bending-torsional coupling method.
