Abstract
This study investigates the seismic performance of equipment on casters through over 1,300 shake table tests, focusing on different caster locking conditions and their effects on trolley motion. Using motion capture, accelerometers, and video recordings, the study accurately monitored specimen movement and caster dynamics. Results showed locking two diagonal casters led to best rolling characteristics that minimizes accelerations and displacements on balance. Twin-wheel casters specially designed for medical applications outperformed conventional single-wheel casters. A linear relationship was established for estimating peak rolling response, offering a practical method for engineers to assess seismic performance of rolling equipment.Description
