一般设计的弯曲疲劳试验机可对试样施加恒定振幅的力,但一次只能试验一个试样。为了测定各种参数(频率、温度,环境)对材料使用寿命的影响,需进行多次试验。为此,我们设计并制成了一台基于定转数原理的试验机。试验方法: 该机的试验方法基于恒振幅原理。在常规的弯曲疲劳试验中,是在悬臂梁的自由端上加荷。而本机所采用的方法是试样的固定
A generally designed bending fatigue tester can exert a constant amplitude force on a specimen, but only one specimen can be tested at a time. In order to determine the impact of various parameters (frequency, temperature, environment) on the service life of the material, multiple tests are required. To this end, we have designed and produced a test machine based on a fixed number of revolutions. Test Method: The test method of this machine is based on the principle of constant amplitude. In conventional bending fatigue tests, the free end of the cantilever is loaded. The method used in this machine is the sample fixed
