Lynx controller

Vibration control system composed of single output generation and multiple channels hardware associated with powerful software.

The LynxTM is a powerful, compact and affordable vibration test control system designed to meet a wide range of environmental test requirements. It combines simplicity of operation required for production screening with the power and versality required for R&D prototype testing. Spectral Dynamics designs and manufactures the complete system (Hardware and Software) to give an extended lifetime to the LynxTM and supports customers over the time.

The LynxTM is a powerful, compact and affordable vibration test control system

The LynxTM   is no ordinary controller when it comes to vibration testing. To meet your most stringent test requirements, the system incorporates patented adaptive digital vibration control methods. Thanks to a hardware with synchronization capability and a user-friendly software, the LynxTM will be your partner to control, analyze and measure.

Key features

4 Input channels expandable
Each module is composed with a drive channels and 4 inputs. Synchronization of modules allows to increase the measurement channels number to fit your application.

Multi-channel control capability
Each input channel can be declared as control channel. If several inputs are selected, the user can easily define the strategy for a multi-channel control of the test.

Advanced graphics & reports
Our team developed for you a powerful graphic interface to monitor your test and visualize data. It allows to configure your display as you want and to export directly your tests report in Word® or Excel®.

Data storage options
You define entirely the storage of the test. The LynxTM will record according your wish the time stream and/or the analysis, no less no more.

Automation features
Sequence of several random profiles? Linking of multiple different control software (Random, Sine or others)? Automation of your tests can be done with Spectral Dynamics solution.

The software can integrate the limits parameters of the test bench as the force of the shaker for example. It prevents us to start a test, which can damage the equipment.

System on Windows 10 – USB3 connection to host
Spectral Dynamics integrates the latest technology in its products. So, the software is running on Windows 10 and hardware is connected with USB3 to the computer.

Test applications

Spectral Dynamics develops its own algorithms in order to always provide the best control. For sine testing, it means a true analog-quality sine sweep with a double precision integrated phase algorithm for low distortion. Thanks to the easy-to-use interface, you can adapt your control parameters: manual or automatic test, control with the fundamental signal (tracking filter) or on the RMS of the broadband, number of control channels and strategy. Swept sine, stepped sine and “Search& Dwell” tests can be performed with the LynxTM.

To perform an optimal random test, Spectral Dynamics developed a control algorithm with separate controls loops dedicated to controlling the shape of the drive spectrum and overall RMS level, which optimizes both control speed and stability. With this tool, the LynxTM is able to “see the future” and adjust the control speed in real time to the next measure of error that is about to happen.

Our solution generates different types of shock pulses to simulate the test item experiences in its real environment. Thanks to its expertise, Spectral Dynamics developed an algorithm for shock testing with transfer function updating and coherence smoothing to accurately and quickly compensate for non-linearity or time varying changes in the dynamic load. In the software, the control strategy is easily defined by the user with pulse compensation, tolerances, number of control channels. SRS testing, automation of the shock test and repetitive pulse mode are only some of the features you can expect with your LynxTM system.

Sine on Random
This application consists in combine tones with random signal. The test starts with the same high-quality random signal generation and control quality that the random application employs. Tones are added with the same quality of signal generation and sweep capability that the sine application employs.

Random on Random
Random on Random simulates complex narrowband random on broadband random vibration environments. Narrow-bands may be swept or stationary. This vibration environment is typically seen in reciprocating equipment, repetitive impacts from tracked vehicles, and aircraft gunfire vibration.

Road simulation (Time replication)
Road Simulation application makes it possible to reproduce actual measured time history vibration data in the laboratory on a shaker system.

Signal Analyzer
The analyzer provides a comprehensive set of tools for data acquisition and signal analysis. Tests can be performed with or without output generation.
