Slip Table Assembly
ST Series
-
The ST Series Slip Table Assembly is one of three base configurations offered by Unholtz-Dickie for its vibration test systems. It is ideally suited for sequential 3-axis test capability with minimized cross axis response; for testing heavy, oversized, or non-symmetrical loads; and for products where orientation with respect to gravity is necessary.

Long Stroke Thrusters
6X Thruster Systems
-
The SA15-6X-S is regarded as an industry standard Long Stroke Thruster Test System. It is widely regarded as the workhorse for production testing of automotive AIRBAG sensors by leading suppliers of automotive airbags and associative control modules. The SA15-6X-S was designed to produce highly accurate and repeatable acceleration pulses in the horizontal plane; pulses such as classical haversine and half sine waveforms, and for simulating actual crash waveforms imported as ASCII amplitude/time history or as a transient capture. The long stroke capability and powerful SA Series power amplifier can reproduce crash waveforms with velocity changes up to 17 MPH.

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.
