疲劳特点是可以实现高负荷、高频率、低消耗,从而缩短试验时间,降低试验费用。疲劳试验机用于进行测定金属、合金材料及其构件(如操作关节、固接件、螺旋运动件等)在室温状态下的拉伸、压缩或拉压交变负荷的疲劳特性、疲劳寿命、预制裂纹及裂纹扩展试验。下面小编就来给大家说一下疲劳试验机的定期维护及存在价值,一起来看看吧。

疲劳试验机用于测试材料在受到重复或者交变应力的作用时,经过多次循环试验后,在没有显著外观变形的情况下是否会发生突然地断裂。统计数据表明,航空工程约有60%~80%的断裂时由于结构材料的疲劳破坏造成的。因为目前的技术尚无法从理论上来预测材料在可变负载作用下的强度性能,所以只能暂时使用材料在可变负载下的疲劳极限和疲劳寿命来替代动态强度性能这一指标。疲劳试验广泛应用于航空航天汽车、船舶、冶金、建筑等行业,与天博体育网质量和人身安全密切相关。因此,保证疲劳试验机的量值准确具有非常重要的意义。

疲劳试验机一般用作材料或者部件的疲劳强度或疲劳寿命试验,在使用该设备的时候也应该注意保养设备零件,最容易出现问题的部件是夹具、电机、钣金以及传感器,下面是保养的一下小方法。
