characteristic1.high degree of automation and efficiency, sealling, injecting, and ejecting automatically of pressure chamber, w/o manual manipulation .2.it will finish 6-8pcs testing per one staff by each day.3.the rate of closed-loop of all channel is 10khz, loading include stress, strain, displacement and arbitrary switching control, it also available for subsection control of stress, strain, displacement, axial direction during testing.4.multiple protection: over load, overvoltage, overheating and misoperation. Pressure chamber adopts the newest double-deck intertwine structure, which enhanced the safety and the explode will never happen.5.built-in pressure chamber of load sensor would eliminate the affect of friction. Besides, improving the measurement accuracy of axial load.6.the controller can connect to usb, hddd and sdhc directly, data can be stored in the controller external device directly, pc as well. Data double insurance to prevent computer crashing and data losing.the the controller can independent working and run stably for a long time.there is any influence while the computer crashed.

The test system provides the static of large torque. In order to meet the test requirements, the system adopts servo motor as the torque power machine and planetary gear reducer as the deceleration and force increasing device, which can provide rated torque of over 100, 000 n. M. Automatic feedstock, automatic card-mount, automatic loading and automatic unloading. The torque value and angle value automatically collecting during whole process. Also could realize the control of closed-loop with torque and torsion angle freely setting, loading time, corner and torque.With real-time recording and storage per computer, data reduction through the data processing and the judgment of the test results;

The system has torque and torsional angle control mode. During the testing, you can choose one of the control mode for testing, also can pre-loading then control curve load and freely switching.

1. This item is testing for static mechanics permance of structure/material/metal parts/girder/frame of naval architecture and ocean engineering, pressing and bending tests of parts etc.

2.Due to the adjustable position of the loading cylinder beam and the horizontal support

beam on both sides, the experimental machine is able to adapt to the test pieces of different sizes. In addition, due to the high machining accuracy of the T type, guaranteeing the high precision by installation of the test pieces after adjusting the position.

3.The control software provides the records including quasi-static loading test software of uniaxial load and bending testing , which can realize of static load, displacement, time-load curve, time-displacement curve and displacement-load curve during the test process.

4.Whole is full hydraulic transmission, with closed-loop servo control. According to the requirement of testing, multiple controlling methods is optional, as load force(stress) and deform displacement(strain) etc, which can convert freely with each other. The control section adopts US imported NI multifunctional closed-loop system and DEXs data processing software, which succeed in high-speed collecting, real-time recording, displaying on time, smart adjustment and control, report processing and standard printing and so on.

Rock triaxial testing machine is the most advanced testing system with two rigid and one flexible loading in China, which can meet kinds of rock specimenss.

The fully closed-loop control of test force (stress), deformation (axial strain, radial strain) and displacement (compression rate) during rock testing process that adopts advanced fully digital coordinated loading measurement control technology and electro-hydraulic servo system.
