With the continuous improvement of material performance requirements in the fields of aerospace, automotive manufacturing, and equipment, the mechanical behavior evaluation of materials under complex stress conditions is increasingly valued. The traditional one-way fatigue test is no longer able to fully reflect the true service state of materials, and the tensile torsional composite fatigue testing technology has therefore become an important means of evaluating the mechanical properties of materials.
The FLPL series microcomputer controlled tensile torsional composite fatigue durability testing machine launched by Fule Instrument Technology (Shanghai) Co., Ltd. is a professional equipment developed for this testing requirement. This series of testing machines is mainly used for tensile fatigue, torsional fatigue, and tensile torsional composite fatigue tests of metal materials, composite materials, and other specimens. It can complete tensile, compression, torsional, low cycle, and high cycle fatigue tests of materials and components. By configuring corresponding accessories and testing software, it can also be used for crack propagation, fracture mechanics, and other mechanical tests.
In terms of core parameters, the FLPL series offers a variety of specifications to choose from: the rated static load test force can be selected as ± 50kN, ± 100kN, ± 200kN, and the indication accuracy is ± 1%; The rated dynamic load test force can be selected from ± 25kN and ± 100kN. The torque configuration is also flexible, and the static torque can be selected from ± 500Nm and ± 1000Nm, with no gear division throughout the entire process. The indication accuracy can reach ± 1% within the range of 2% to 100%; The dynamic fatigue torque can be selected from ± 200Nm and ± 800Nm. The actuator amplitude is ± 75mm, the torsion angle is ± 50 °, and the frequency range is 0.01-50Hz, which can cover various scenarios from low-frequency heavy loads to high-frequency dynamic testing.
In terms of system configuration, the equipment adopts a high stiffness fatigue testing machine framework and an optimized hydraulic system, which has the characteristics of stable pressure, smooth start stop, safety, reliability, and no leakage. Equipped with high-precision fatigue tension torsion composite sensors and a fully digital dynamic servo measurement and control system, it supports multi-channel closed-loop control and can achieve various test waveforms such as sine wave, triangular wave, rectangular wave, and combined wave. The clamping force of its fixture can be infinitely adjusted through a pressure reducing valve, which can simultaneously adapt to the clamping requirements of small load brittle materials and large load plastic materials, ensuring the reliability of the test.
In terms of functional expansion, the FLPL series can be equipped with high and low temperature testing systems or high temperature testing systems to achieve tensile and torsional composite testing in high and low temperature or high temperature environments. The supporting tensile and torsional fatigue test software can automatically complete constant amplitude dynamic tests, covering low cycle fatigue, constant amplitude fatigue, crack propagation and other test items. Data processing and report generation are convenient and efficient.
The FLPL series microcomputer controlled tensile torsional composite fatigue durability testing machine from Fule Instrument provides strong technical support for material research and quality testing with flexible configuration options, reliable technical performance, and professional testing software. It is a professional equipment choice worth paying attention to in the field of material mechanics testing in China.
