Before understanding the classification of fatigue testing machines, let's learn from common practice, what is fatigue testing machine? Fatigue testing machine is a kind of equipment used to test the fatigue performance test of metal and alloy materials under specific conditions, such as tensile compression, tension and compression alternating load, bending torsion and so on.

 

 

今天我们就从5个方面来对疲劳试验机进行分类：

Today we classify the fatigue testing machine from 5 aspects:

 

 

一、按试样的加载方式可分为：拉-压疲劳试验、弯曲疲劳试验机、扭转疲劳试验、复合应力疲劳试验。弯曲疲劳试验又可分为旋转弯曲疲劳试验、圆弯曲疲劳试验、平面弯曲疲劳试验；又可分为三点弯曲、四点弯曲、悬臂弯曲疲劳试验；

First, according to the loading mode of the specimen, it can be divided into: tension compression fatigue test, bending fatigue tester, torsion fatigue test and compound stress fatigue test. The flexural fatigue test can be divided into rotating bending fatigue test, circular bending fatigue test and plane bending fatigue test, and can be divided into three point bending, four point bending, and cantilever bending fatigue test.

 

 

二、按应力循环的类型可分为：等幅疲劳试验、变频疲劳试验、程序疲劳试验、随机疲劳试验等；

Two. According to the type of stress cycle, it can be divided into equal amplitude fatigue test, frequency conversion fatigue test, program fatigue test and random fatigue test.

 

 

三、按试样破断时应力（应变）循环周次高低可分为：低周疲劳试验、高周疲劳试验。失效循环周次大于5X104的称为高周疲劳试验，小于5X104的称为低周疲劳试验；

Three. The cycle of stress (strain) can be divided into low cycle fatigue test and high cycle fatigue test. The cycle of failure is greater than 5X104, www.yanglaoyuany.com.cnwww.yanglaoyuana.cn www.jianchajingmujuu.cn www.gangmoju.net.cn www.dianlancao.net.cn www.uxingcaomoju.com.cnwhich is called high cycle fatigue test. Less than 5X104 is called low cycle fatigue test.

 

 

四、按试验环境可分为：室温疲劳试验、低温疲劳试验、高温疲劳试验、热疲劳试验、腐蚀疲劳试验、接触疲劳试验、微动磨损疲劳试验等;

Four, according to the experimental environment, it can be divided into room temperature fatigue test, low temperature fatigue test, high temperature fatigue test, thermal fatigue test, corrosion fatigue test, contact fatigue test and fretting wear fatigue test.

 

 

五、按试样有无预制裂纹可分为：常规疲劳试验、疲劳裂纹扩展试验。

Five. According to whether there are prefabricated cracks in specimens, it can be divided into routine fatigue test and fatigue crack growth test.

 

 

        以上就是关于疲劳试验机的分类情况了，相信大家在看完以后也对如何选择适合的疲劳试验机有了一定的了解，如果大家需要购买疲劳试验机，也欢迎向我们询价。

The above is about the classification of the fatigue testing machine. I believe that you have a certain understanding of how to choose the suitable fatigue testing machine after reading, and if you need to buy fatigue testing machines, you will also welcome an inquiry.
