Second, performance characteristics:

• Dual-purpose, dual load:The static load is loaded by the ball screw driven by the motor, and the dynamic load is loaded by electromagnetic resonance, which eliminates the mutual interference between the dynamic and static loads。Combining dynamic test function with static test function, dynamic and static dual use can be realized.

• High frequency low consumption, accurate control:High test frequency, low electromagnetic resonance energy consumption (about 3% of the electro-hydraulic servo fatigue testing machine), servo motor to achieve fast and accurate average test force control;

• Scientific design, high strength frame:With 4 columns and 4 (2) ball screw design, the main frame has high rigidity and good stability;

• Multiple protection, flexible expansion:The equipment is equipped with multiple protection functions, including overload protection, mechanical limit protection, driver overcurrent protection, fracture protection, frequency reduction protection, load upper and lower limits protection。Fully ensure the safety of equipment and personnel。At the same time, the device includes a T-slot workbench for easy expansion of accessory configurations。

• Closed-loop control, accurate and reliable:DSP full digital closed-loop control, to achieve fast and accurate test force control, to ensure accurate and reliable data。

• Real-time display, easy operation:Software control system, using C language programming, efficient and fast;Dynamic and static loads can be set separately or simultaneously during the test。At the same time, static force, cyclic force, displacement, voltage, frequency, period, pulse width, deformation and other data can be displayed in real time。
