Design of Slip Horizontal Table System For Shaker

Abstract

Shakers can produce vibration functions at the desired frequencies and amplitudes according to the vibration standards. Also, shakers have the same working principle with devices of hydraulic, mechanical pneumatic, electromagnetic etc. Shakers can produce vibration in the vertical and horizontal direction depending on the type of table. The test sample was fixed on the table with fixture. In this study, the appropriate slipe table was designed and manufactured in order to improve test capability of shaker. Therefore shaker had the capability of vibration drive in the horizontal directions for test sample. Finite element method (FEM), modal analysis, harmonic analysis and vibration measurements were applied to assess vibration analysis. After, results of FEM and confirmation experimental were in a good agreement with each other, the design of vibration shaker table system was manufactured.
