Brief introduction: This test bench with the method of electro-hydraulic servo, a full set of equipment are made by the computer measurement and control, and form a complete set of test software, including test control, data acquisition and processing, can realize simulation of vertical work state of the specimens, one million (106) over the fatigue test. Methods: load - frequency Control loading waveform: sine wave This equipment is equipped with can build special high and low temperature test chamber environmental conditions, can be carried out at room temperature and to 40 ℃ ~ 200 ℃ high temperature environment test. Through a specially designed to promote (out), which can realize has high and low temperature boundary conditions and no high and low temperature environment condition and test function. Technical indicators: Control system: adopting closed-loop computer control displacement and load data. Control mode: displacement or load - frequency automatic switch control, manual control and automatic control; Continuous linear measurement under variable loading rate, make the control function is stable and reliable. Loading waveform: sine wave Data acquisition, which can realize the load, displacement and frequency data real-time display. High precision acquisition, acquisition frequency 10 k or higher. Security: to load, displacement, stress and temperature with parameter setting and overrun protection function. Maximum load: 100 kn plus or minus 0.5% resolution: 1/10000 Displacement measurement: 0 ~ 100 mm + / - 0.2 mm resolution: 0.1 mm The maximum amplitude, plus or minus 15 mm Load control: + 10% Displacement control: plus or minus 10 mm Pressure control: + 10% Outside diameter control: + 20% Sample size: 15 * 15 cm The oil temperature control: + / - 5 ℃ Voltage protection: + 10% Under voltage protection: - 15% Leakage protection:
