Servo-Hydraulic Actuators for Load Application

Three servo-hydraulic actuators (Make: MTS Systems Corp., USA) have been acquired to enhance the load application capability of the existing Cyclic Testing Facility. One 500kN (Model: 243.45T) was purchased during 2000-01 and two 100kN (Model 244.22) were acquired during 2005-06. These actuators can apply loads in both displacement- and load-controlled mode to simulate various structural loading environment. These are essential loading equipment for simulating loading environment typical for earthquakes; however, they can be used for gravity loads simulation as well.

Technical Specifications:

Force Capacity: +/- 500 kN and +/- 100 kN; Stroke : +/- 125 mm. Swivel Base and Swivel Head. Controller for actuators are capable of applying programmable loading cycles under load, stroke and strain control mode apart from standard sine, ramp, triangle, etc. function for cyclic tests. The actuators are being operated using Hydraulic Power Supply available in the laboratory having the flow capacity of 237lpm at 2.1 MPa.
