In dynamic structure test, the specimen of hydraulic servo shaking table contains not only inertia load but also elastic load. The specimen herein is simplified as a spring-mass-damping system, and the mathematical model of the hydraulic servo shaking table is established by theoretical analysis. The coupling between specimenampx2019s elastic load and shaking table itself produces resonance ...
The advantage over a shake table is the ability to test much larger structures, without requiring large and more expensive hydraulic power systems, shake tables, and actuators with high flow servo valves. Triaxial Rock Testing Machines. Servo Hydraulic Solutions manufactures Triaxial Rock Testing Machines to meet any requirement.

Oct 14, 2010 To hold these kinds of tolerances requires more than a go, no-go hydraulic control valve. Servo directional valves are the only hydraulic valves capable of controlling oil flow andor pressure rapidly and precisely. Servo directional valves are 4-way, 3-position spool valves with all ports blocked in the center position.
About Servo Hydraulic Systems. Led by Doug Weller, Servo Hydraulic Solutions in Boulder, Colorado uses commercial off-the-shelf components allowing a unique end product-be it an earthquake simulator, vibration testing system or earthquake shake table. We listen to customers and propose ideas that support your individual needs.
On the other hand, even with a well-organized and efficient team settled at the factory, we need to use the competency of high-precision equipment in proportional and servo valves periodical. We own an advanced testing unit for hydraulic valves. After repairing and testing Moog hydraulic valve or any other defective valve, the repaired valve will be tested under real-life working conditions. Depending on hydraulic valve type, the fixed hydraulic valve will be fully operated. In the table ...
