Affiliations

The LSVR is also proudly affiliated with several OSU-based research centers:

LSVR is affiliated with the SIMCenter which provides massive computational resources via local blade-based CPUs and through on-demand access through the Ohio Supercomputer Center. Software licenses include COMSOL, LMS VirtualLab Acoustics, ANSYS, ADAMS, etc.

LSVR is affiliated with the Center for Automotive Research (CAR) which provides access to a Large hemi-anechoic chamber (approximately 30 ft by 30 ft by 20 ft usable volume) and additional experimental space as needed.

LSVR is affiliated with the Smart Vehicle Concept Center which provides an excellent avenue for industry, government, and commercial sponsors to leverage LSVR expertise and resources for research purposes falling in the scope of adaptive, smart material and structural systems for vehicle-related application.
