System for Closed Loop Vibration Control -
The LMS Test.Lab Advanced Design Validation Testing solution is a complete system for closed loop vibration control for random, sine and shock test modes, including the advanced random response limiting and sine notching capabilities. The system allows safe, accurate and fast reproduction of the target qualification reference profiles, using up to 60 control channels. Any channel when not used for control can be used as an auxiliary measurement channel or response-limiting channel for test specimen protection. The channels support ICP transducers or any Voltage signal. The test results can be used for post-test 3D animation to help engineers understand the structural dynamics of the test item.
The higher channel count system and the included possibility to apply random response limiting or sine notching, allows an even more complete test item protection as well as to perform accurate post-test analyses without the risk of spatial aliasing.
With the included Compare runs add-in worksheet, engineers have an extremely productive tool to browse through all test data at the end of a run, including an automatic overlay of equivalent curves from any set of previous runs. Any change in dynamic behavior between runs is made immediately visible.
The Geometry workbook allows the quick generation of wireframe models for full 3D animation of the test and analysis results. The Operational Deflection Shapes workbook ensures easy navigation and selection of the acquired qualification test data, and animation of the vibration pattern at any given frequency.
The LMS Test.Lab Advanced Design Validation Testing solution provides data acquisition and vibration control functions for product qualification testing. The system’s processing, data management, and analysis tools give the necessary engineering feedback to further guide the design and development effort. It is primarily used in the aviation, space and defense industries. The system is optionally expandable to hundreds of channels.
