YAJ series of computer controlled electro-hydraulic servo use compression-shear testing machine is mainly used for a variety of bridge-type, rubber bearing basin compressive, shear strength under complex conditions, the detection rubber bearing radial compressive axial , shear, corner mechanics. Can be rubber bearing compression elastic modulus, shear modulus of elasticity, allow the shear angle, friction coefficient and ultimate compressive strength and other mechanical properties. This machine adopts industrial computer as the core P4 digital closed loop electro-hydraulic servo control system, can fully meet the "JT / T4-2004 highway bridge laminated rubber bearings and other mechanical properties testing required by the rules" requirement. It can also sample the modulus of elasticity of other materials such as concrete and compression performance testing and completion of the combination wave test low cycle, triangle wave, sine wave, trapezoidal wave, is the research and production, arbitration test required advanced detection equipment. This machine is composed of five parts by the four pillar type hydraulic pressure test system axial and transverse horizontal shear test systems, test equipment corner, multi-function hydraulic servo oil source, computer servo control system. YAJ series of computer controlled servo pressure shear testing machine Main features ◆ control measurement system used by the US AD's original device, measurement and control accurate and reliable, very low failure rate. Test force and deformation measurement resolution of up to 200000. Displacement measurement resolution of up to 2m. ◆ servo oil source by the Japanese original internal gear pump, low noise, long continuous operation can be adapted. ◆ Main sensing element manufactured using imported components, to ensure accurate and reliable measurement, and the use of computer data processing, ensuring reliable calculations and fair. ◆ machine uses intelligent design, high degree of automation, measurement accuracy, fully functional, high reliability, simple operation, easy to use. Compressive modulus of elasticity can be done automatically test, shear elastic modulus and allowable angle test, compression test, friction coefficient, corner test. ◆ test software using self-developed VC ++ language programming, advanced modular design, software for easy and reliable operation can be extended to the Windows98,2000, XP, NT operating system working under and a perfect software from picking function.
