Controlling Out Harmonic Distortion on a Hydraulic Shaker
Harmonic distortion is commonplace on a hydraulic shakers, and driving such a system with a pure sine tone does not generate a pure sine tone response. The problem can be particularly bad at the higher velocities around 20-50Hz. This presentation will investigate a novel method implemented in the shaker’s controller which counteracts harmonic distortion generated when the shaker is driven with a pure sine tone. In tests run on a hydraulic actuator, the THD was observed to drop by 95%.

Introduction to Multii-Shaker Testing
This training course will cover the basics of multi-shaker (MIMO) testing. The training will begin with a focus on a two-shaker setup and expand to cover full 6 Degree of Freedom (DOF) testing. The training will utilize a live dual-shaker table to reinforce concepts and offer attendees insight into the challenges of multi-shaker and multi-DoF control.
The course will include:
• Vibration Fundamentals
• Digital representation of a vibrating system
• Degrees of Freedom
• Effect of modes
• Multi-Shaker Control
• Common Multi-Shaker Configurations
• Concepts behind Impedance Matched Multi-Axis Testing (IMMAT)
About the Event
The annual Shock and Vibration Symposium is the leading forum for the structural dynamics and vibration community to present and discuss new developments and ongoing research. The Symposium was established in 1947 and typically includes both unclassified (unlimited and limited distribution) and classified sessions.
Topics covered at the symposium include shock-ship testing, water shock, weapons effects (air blast, ground shock, cratering, penetration) shock physics, earthquake engineering, structural dynamics, and shock and vibration instrumentation and experiment techniques.
Over 200 technical papers are typically presented. Panel discussions address topics such as new software developments or accelerometer isolation problems. Tutorials provide up-to-date technology overviews by leading specialists.
HI-TEST Laboratories is responsible for all planning and operational aspects of the symposium.
This will be HI-TEST’s 24th consecutive year of running the annual Shock and Vibration Symposium.
