The computer collects and controls through our company's fully digital control system, directly controls the fully digital speed-regulating motor via the fully digital speed controller. The motor speed is reduced by the arc synchronous reduction system and transmitted to the precision ball screw pair to realize the rise and fall of the crossbeam, completing tensile, peeling, compression, and other mechanical property tests of the sample.
The testing machine's professional software automatically calculates data such as fixed elongation, fixed force elongation, tensile strength, sample elongation, upper and lower yield points, and yield strength, and also meets displacement holding control. The computer control system's control of the test process and data processing complies with the requirements of national standards for metals, non-metals, and composite materials. Test reports are diverse, such as in WORD, EXCEL, and other formats.
This machine is pollution-free, low-noise, highly efficient, and has a wide speed regulation range. It is suitable for testing various mechanical property indicators of metals, non-metals, and composite materials, fully complying with national standards.

Special test items:
Elastic coefficient, i.e., Young's modulus of elasticity
Definition: The ratio of in-phase normal stress component to normal strain. It is a coefficient to measure material rigidity; the higher the value, the tougher the material.
Proportional limit: Within a certain range, the load and elongation can maintain a proportional relationship, and the maximum stress is the proportional limit.
Elastic limit: The maximum stress that the material can withstand without permanent deformation.
Elastic deformation: After removing the load, the material's deformation completely disappears.
Permanent deformation: After removing the load, the material still retains deformation.
Yield point: When the material is stretched, the deformation increases rapidly while the stress remains unchanged; this point is the yield point. The yield point is divided into upper and lower yield points, generally the upper yield point is taken as the yield point. Yield: When the load exceeds the proportional limit, the elongation is no longer proportional to the load, the load suddenly drops, and then fluctuates up and down for a period of time, with significant changes in elongation; this phenomenon is called yielding.
Yield strength: The load when the permanent elongation rate reaches a specified value, divided by the original cross-sectional area of the parallel part.
Spring k value: The ratio of the in-phase action component to the deformation.
Effective elasticity and hysteresis loss: On the tensile machine, stretch the sample to a certain elongation rate or a specified load at a certain speed, measure the percentage ratio of the work recovered during contraction to the work consumed during extension, which is the effective elasticity; measure the percentage ratio of the energy lost during elongation and contraction to the work consumed during elongation, which is the hysteresis loss.
