Compact and quiet three axis shaker tables for simultaneous excitation in x-, y- & z-axis
Our compact and quiet MATRIX 3D vibration tables allow simultaneous excitation in x, y and z axis. Real load scenarios and noise-critical excitation conditions can be accurately reproduced in the laboratory in a single test in several axes. Time-consuming conversion work for sequential excitation of individual axes is no longer necessary.
The excitation of the three axes is performed by very quiet, compact shakers of our ALPHA series. Excitation forces of up to 8kN per axis and vibration displacements of 25mm allow the universal use of the MATRIX 3D shaker tables for Squeak & Rattle, functional and durability tests. Depending on the application, 3D vibration tables are available in three different sizes and performance classes.
A closed-loop multi-axis vibration control system (MIMO controller) enables exact, reproducible excitation in one, two or three axes with a wide variety of excitation signals such as sine sweep, random excitation, recorded time history data, square wave signals or externally generated wavelets. Crosstalk between the individual excitation axes is actively compensated and minimized by the vibration control system if required.
The compact design and the resulting small footprint of the MATRIX 3D vibration tables allows integration into smaller acoustic rooms and test laboratories.
