【 摘 要 】

In this paper, we propose a selection method of the increased amplitude stability parameter for the unstable motion problem of the uniaxial shaker before its stable operation. On the basis of single-axis shaker dynamics equations, an ADMAS and AMESim combined simulation model is established. According to this model, the vibration characteristics under different parameters are solved by using the control variate method. The simulation results show that the motor speed, the eccentric mass and the inclination of screen surface are the three main factors which affect work starting state of uniaxial shaker. The working efficiency of uniaxial shaker is controlled by the motor speed while the amplitude is affected by the eccentric mass. Moreover, the inclination of screen surface plays a decisive role in the distribution of the vibration track before uniaxial shaker reaching the stable operation state. The relatively stable movement is obtained by optimizing the parameters, which provides a new way to improve the stability of uniaxial shaker.
