| Abstract: | A kind of earthquake simulator that takes PSS typed parallel mechanism with redundant inputs as the principle part has been put forward. Eight servo motors were adopted for the input of this earthquake simulator, and six di mensional movements can be realized. Under the consideration of elastic deformations of each leading screw system and branch chain system, the static stiffness model of earthquake simulator was established, the example of numerical computation was presented. The result shows that the adoption of branch chain with redundant inputs could effectively enhance the stiffness of earthquake simulator. |
