Model: LY-RB-5000J
Characteristics
Electromechanical testing machine for performing bending fatigue tests on rotation symmetrical components with rotating load application:
•Nominal capacity: 120 N·m;
•Testing rotation speed:1500 – 5000r/min(25Hz-85Hz)
•Clamping diameter: diameter 12 and 17(other size can be customized)
• Constant bending moment over the entire free specimen length by four-point rotating bending load.
• Space-saving due to compact design
Principle of test
Nominally identical specimens are used, each being rotated and subjected to a bending moment. The forces giving rise to the bending moment do not rotate. The specimen may be mounted as a cantilever, with single-point or two-point loading, or as a beam, with four-point loading. The test is continued until the specimen fails or until a pre-determined number of stress cycles have been achieved. Comply to ISO1143-2010
Specification
l Loading arm: 200mm;
l Relative error of arm length: ≤± 0.3%; The distance between the left and right fixtures can be adjusted.
l Coaxiality of left and right fixtures: ≤ Ф0.02mm；

l Relative error of left and right bending distance: ≤ ±1%；
l Repetitive relative error of bending distance: ≤ ±1%；
l Maximum count: 109; Counting error: ±1；
l Heating temperature range of high-temperature furnace: 300℃～1000℃；
l Temperature fluctuation:
Testing temperature T | Temperature fluctuation |
T≤600℃ | ± 3℃ |
600℃＜T≤900℃ | ± 4℃ |
＞900℃ | ± 5℃ |
l The temperature uniformity in the furnace of the working part of the sample shall not exceed 15 ℃.
l Equipped with touch screen operation and display panel for setting all control parameters and displaying all measurement data show all experimental operations;
l The number of experimental cycles can be set arbitrarily, once the set value is reached, it will automatically shut down and have a power-off protection function.
l Both the front and rear fixtures use elastic cone sleeves to clamp the sample, achieving precise fitting.
l It has complete protection functions, such as power-off protection, motor overcurrent protection, automatic shutdown protection for sample breakage. Furnace temperature protection and other equipment are equipped with transparent protective covers, and the testing process can be unmanned.
l When configuring a computer, distributed measurement and control can be performed on a single testing machine or multiple testing machines. The computer uses WINDOWS as the working platform and adopts virtual panel operation mode. The interface is clear, the operation is convenient, and the program is standardized and stable. It completes the collection, processing, storage, and printing of the entire equipment test data; The entire process test data, test status, and the time at which each test status occurs can be automatically stored on the computer hard drive; For intermittent fatigue testing, the test process data can be automatically continued to maintain the integrity of the test process data;
l The verification data can be printed as a report, and its format can also be converted into commonly used software document formats, such as Word, Excel and so on.
