Square vs Rectangular Control Vibration Testing of an Aerodynamically Excited Structure

摘要

1. Rectangular control offers significant benefits over Square control in simulating vibration caused by a distributed loading 2. Huge reductions in the over-test across the test structure 2.1. Global vibration responses much more representative 2.2 Any single degree of freedom may have not be as a good you could achieve with a different control strategy 3. Significant reductions in peak force requirements 3.1 This can lead to big cost savings, both in infrastructure and operating costs.
