Digital servo controller
Automobile crash simulation analysisHigh speed testing machine system
High speed tensile testing machine is one of the basic methods to understand the relationship between material properties and deformation velocity.
This machine can be used to determine the tensile, compression, bending and shear test of metal and nonmetal materials and components.
The test system adopts electro-hydraulic servo closed-loop control system, advanced technology, can carry out continuous control of the output, a fast response speed, anti load stiffness, speed accuracy is higher than other fast loading method.
Functional characteristics
* Advanced testing machine control technology, the realization of displacement control, test force control, strain (full digital three closed loop) control, and can be used for smooth switching.
* Professional design of automatic control and data acquisition system, the data acquisition and control process of the full digital.
* Has any test point set and keep the function.
* The results show that the stress-strain curve, the force deformation curve, the force displacement curve, the force time curve, the deformation time curve, the displacement time curve, the force strain curve.
* The utility model has the functions of limit protection, overload and overcurrent protection of any working position, and is reliable and safe.* Build a strong test database, test data can be saved at any time, query, call.
* The experiments are carried out under sine wave, triangle wave, Fang Bo wave, trapezoidal wave, oblique wave and user-defined waveform.* The computer realizes the function of load control, data acquisition and display, data processing, curve drawing and so on.
* The software comes with the national standard or industry standard test method, which is more convenient for data entry and data processing and maintenance.
