旋转梁疲劳试验

旋转梁疲劳试验 generates higher frequencies than traditional 高周疲劳 方法. Our testing services provide critical data about coatings and metallic surface treatments to ISO 1143, ASTM F1160标准, or bespoke 方法 to meet your test requirements. 

旋转梁疲劳试验

旋转梁疲劳试验 is a mechanical test method used to evaluate the fatigue properties of materials. 在这个测试中, a beam specimen is subjected to cyclic loading, which induces repeated bending causing failure over time. The specimen is mounted on a rotating apparatus, which allows for the cyclic load to be applied at constant amplitude and frequency.

考试期间, the beam specimen is rotated at a constant speed while a loading force is applied to it. The force causes the beam to bend, 当光束旋转时, it undergoes cyclic bending stress that can induce fatigue failure.

The data generated can be used to design and optimize materials for use in applications where fatigue failure is a concern, such as the 航空航天 and 汽车 industries.

Rotating beam fatigue test preparation and process

Before the test, our labs grind and polish samples to ensure the most accurate results. Depending on the goal of your project, testing is either run to a set number of cycles or to failure. If the specimen fails, our experts can provide 失效分析 to determine what can prevent future occurrences. 

Test 方法 ISO 1142 and ASTM F1160

In addition to our ISO 1143 rotating bar bending 疲劳测试 and ASTM F1160 shear and bending fatigue test programs, our experts can assist in performing custom and unique 旋转梁疲劳试验 方法.
