Brief introduction: SDS series of shock absorber performance test machine can do all kinds of shock absorber dynamometer test, friction test and temperature characteristic test, etc. Full compliance with the latest automotive shock absorber technology conditions and bench test method for shock absorber testing equipment in the draft of technical requirements. It is mainly used for: more speed indicator test; Temperature characteristic test; The friction test; Bubble test; Damping force frequency characteristic test; Conventional fatigue test; Road spectrum test; Double acting fatigue test; Frequency sweep test; Combination wave test. Features: 1. A variety of control compensation function (including the peak valley value compensation, amplitude, phase compensation inverse dynamic response adaptive compensation, etc.), users almost do not need to adjust the P, I, D parameters can automatically compensate sample stiffness. 2. The advanced digital signal processing technology, system resolution for 19. A linear correction sensor calibration by 19 points. Sensor signal with a variety of filters, provides the high precision, low noise, low drift performance, to further ensure the accuracy of the measurement results. 3. Can be combined for user-defined SPC test, and the control mode in the preset automatic switch control mode in the process of test. 4. The function generator waveform variety, in addition to conventional waveform can also accept external input waveform and specify the format of spectrum represent the waveform file. 5. The system sample frequency up to 6 KHZ. Provides the analog quantity and digital quantity input/output interface, data acquisition and graphical display function, complete limit and failure protection function. 6. Achieve channel coordination between compensation and independent control function. Control system can control the actuator and the lateral force loading actuator, realize coordination load function. 7. With optional software function. According to the actual need to choose the required software. Its special shock absorber test software, simple operation and test range, all types. Technical parameters: Static load rating: plus or minus 20 kn Accuracy: static load is superior to the value plus or minus 1%. Test show load: + 500 n The friction load precision: better than that of plus or minus 1% Friction displacement accuracy: + / - 1% f. S. Can be applied to a lateral force (open loop) : 0-500 n is adjustable, the static accuracy + / - 1%, can be displayed. Actuator rated displacement: + 100 mm Frequency range: 0.01-10 hz Test speed: 0-1.6 meters/seconds, top speed 46 m/s. Work pressure oil source: 21 mpa Traffic: 160 l/min
