Slip Table Assembly
CSTA Series
-
Unholtz-Dickie introduced the Combined Slip Table Assembly (CSTA) in the late 1960''s to meet the demand for positive mechanical alignment between the shaker and its companion horizontal slip table. The challenge was to achieve this positive, permanent alignment feature without requiring an expensive seismic mass in the vibration lab floor. The original CSTA design has been continuously improved over the years and has now become the industry standard for permanently aligned, integral reaction mass slip tables.

Slip Tables
-
Unholtz-Dickie offers three configurations for fully integrated slip table assemblies for vibration testing; the ST Series, HST Series and the CSTA Series. Horizontal slip tables are used for three-axis sequential testing (x, y, z axes) or used when it is necessary to maintain product positioning with respect to gravity.

Vibration Control & Analysis Systems
APEX Series
-
The UD APEX Vibration Controller is now available with up to 32 input channels. Two hardware configurations are offered, the popular APEX SL with 4-16 channels, and the all new APEX PRO with 20-32 channels (both configurable in 4 channel increments). Each unit offers the latest technology in digital signal processing and shaker control algorithms providing real time vibration test control for Random, Sine, Shock, Resonance Dwell, SRS, Random on Random, Multi-tone Sine on Random, Multi-Sine Control, TRAC (time replication acceleration control) testing and Transducer Calibration, as well as extensive data acquisition and analysis. The vibration controller modular software may be initially customized for specific applications or easily expanded in the future without performance penalties. The vibration controller software provides an abundance of comprehensive features that ensure simple, safe, accurate and reliable vibration testing.
