This machine satisfies GB/T16491-2008 and JJG139-1999 and also complies with GB, ISO, ASTM, JIS and other standards about test requirements for geotextile, geogrid and other materials. If equipped with special grips (used for tensile, puncture, bursting, and tearing tests) and special software, it can automatically calculate upper and lower yield force, proof strength of non-proportional elogation, proof strength of total elogation, tensile strength, elastic modulus and other mechanical property indexes of various materials.
1) main machine
tUsing door frame structure, paint baking shell with nice appearance;
tScrews only bear tension so that it can effectively prolong service life and rigidity;
tUsing precise ball screw assembly loading mode, with double nuts screwed tightly, which ensures system high rigidity and high dynamic property;
2) AC servo speed regulation loading system
tUsing fully digital AC servo motor and driver, precise planetary wheel speed reducer, which is the special matching product for servo motor and directly connects with motor with small volumn, high efficiency, low noise. With features of high rigidity, large acceleration, high reliability.
tAC servo motor has speed regulation ratio up to 10000 times, so that it can make moving speed of crossbeam stepless within 0.05-500mm/min. With perfect overcurrent and overvoltage protection functions; embedded with acceleration and deceleration running mode, swifting smoothly and stably.
3) Full hardware built-in control system
tEmbeded fully digital electrical control technology: completely realizing constant speed control to displacement, test force and strain, with perfect control property, fully digital hardware realization mode, powerful anti-interference capability and good stability;
thigh integration software: applicable to corresponding material testing requirement for different customs (our data acquisition system has passed the verification from National Material Testing Center and has reached leading domestic level).
