CARRILLO, Julián; PORRAS RODRIGUEZ, Pahola  and  SANCHEZ CRUZ, Martha. Educational Tool for quasi-Static Testing of Small Structural Specimens. Rev. Cient. Gen. José María Córdova [online]. 2016, vol.14, n.18, pp.149-165. ISSN 1900-6586.

The paper proposes an educational tool for applying quasi-static loads during tests on small structural elements and systems. The magnitude of forces applied to prototypes is initially evaluated using simulations carried out in SolidWorks and Labview. Actuators having capacities of 300 kN, 50 kN and 20 kN were then selected and connected to the load frame of the Lab. Design and assessment of the elements of the hydraulic system, such as the pump, valves and the electric power board, were then performed. After that, the design of the load and displacement control system and the acquisition system, were designed. These systems involve a proportional controller and a connector block to acquire the signals defined by the system, respectively. It is expected that the proposed system promotes academic and research activities on the performance of small structural models subjected to different types of quasi-static forces.
