Digital Vibration Controllers
D-59 Series Digital Vibration Controllers for Windows 10, which can be used for not only Electro-dynamic Shakers but also Hydraulic Shakers, are featured by user-friendly usability thus enabling complicated vibration tests to be carried out easily as well as a variety of control functions available such as Sine, PSD Random, Shock, Mixed Mode, RSTD, Waveform Reproduction etc. and also input channels being expandable up to 8.
Two Main Controllers with High Expandability
By relevant license keys as options, the controllers can be expanded to the other control functions, increase in input channels (in a unit of 2 channels - for the D-0960 additional hardware also needed).
D-59 Series
・Single-axis Control・Multi-axis Sequential Control
Input: 4 channels as standard, expandable up to 8 channels
Output: 1 channel for control & COLA output as option
D-0960 Series
・Multi-axis Simultaneous & Sequential Control・Single-axis Control
Input: 6 channels (for 3-axis), 4 channels (for 2-axis) as standard
Output: 3 channels (for 3-axis), 2 channels (for 2-axis) as standard
Easy Operation
"The easier, the better!" - required for any Controllers: Featured by easy-to- recall test patterns used often and also easy-to-change test conditions or make new test patterns for everyone.
A Variety of Add-on Software Available
- Resonance Search, Track & Dwell (RSTD)
RSTD performs a resonant frequency tracking and dwell in real time, suited to fatigue tests. - Sine on Random Control (SoR)
SoR, combining fixed or swept sine tones with broad-band random vibration, is used for simulation of rotating devices of vehicles （automotive power trains, helicopters etc.） - Random on Random Control (RoR)
RoR is such control as combining narrow bands of random vibration with broad-band random vibration. - Shock Response Spectrum (SRS)
SRS, Integrated with classical shock and transient shock, is also available.

Transient Time History Control (TTH)
Up to 32k points waveform time-domain data can be imported into the Controller and be simulated, most suited to:
・Transient Phenomenon Simulation Against Trouble Events
・Seismic Simulation
・Collision Simulation
Road Simulation (LTH-Long Time History Control)
For longer waveform simulation (longer than 32k points), LTH Road Simulation software Is also available.
