Modelling And Design Of Shaking Table Test Facilities

The design concept of the UPRM Earthquake Simulator was the design of a small unidirectional electrohydraulic shaking table facility. The initial design concept consisted of a rigid platform sliding over a near frictionless linear bearing system and driven by an actuator attached to a reaction mass.
