Dynamic Behavioral Analysis of an Antiseismic Support under an External Kinematic Disturbance

Study is made of the dynamic behavior of an antiseismic support, which is a heavy homogeneous ball rolling within a cycloidal cavity between mobile upper and lower slabs, subjected to an external kinematic disturbance. The equations of motion are derived for the heavy ball moving in the cycloidal cavity without slipping, and the dynamic effects in this, new earthquake-protective system are analyzed numerically.
