The research missions of the Structural Dynamics and Controls Lab (SDCL) at the University of Michigan are to create novel analysis, design, and control methodologies for achieving better understanding and advanced system dynamics performance (e.g. high adaptivity, high stability, high precision, low vibration, etc.) of emerging mechanical structures. The lab is directed by Dr. K. W. Wang, Stephen P. Timoshenko Collegiate Professor of Mechanical Engineering. Recent research activities are in the following areas:
- Active, semi-active, and active-passive vibration and shape controls
- Adaptive materials-based structural systems
- Biologically inspired adaptive structures
- Modular adaptive metastructures
- Nano composites for damping and damage identification enhancements
- Structural health monitoring
- Vehicle and powertrain system dynamics identification and control
- Vibration-based energy harvesting
The SDCL research projects are funded by various industrial and government sponsors. Past and present sponsors include Air Force Office of Scientific Research, Army Research Office, DARPA, Eastman Kodak Company, Electrical Power Research Institute, Ford Motor Company, General Motors, Jet Propulsion Lab, Lord Corporation, NASA, National Rotorcraft Technology Center, National Science Foundation, Office of Naval Research, and Teledyne.
The Lab has a variety of experimental and computational facilities. Experimental equipment include DSPACE and other high-speed DSP board based digital controllers, laser vibrometers, spectrum analyzers, data acquisition and signal processing units, modal analysis equipment, and wide range of instrumentation such as shakers, fiber optics displacement probes, and specialized high voltage power supplies. Various specialized testbeds have been developed in the lab for experimental investigations, such as system damping and energy harvesting bi-stable sub-assembly testbed, periodic structure control testbed, reflector surface control testbed, and automotive powertrain piezo-hydraulic actuator dynamic test stand.
Throughout the years, the SDCL has created new paradigms, pioneered innovative and bold directions, and made significant contributions and impacts to the research field as well as to industry. Please follow this link for some highlights of our contributions and impacts.
