    超声波疲劳试验机的作动器是采用压电元件产生的20kHz振动波形,经放大后加载到𒆙样品上,实现高速🌄度的疲劳试验。

 

 特 点:

· 能以20kHz的重复频率快速评价金属材料的疲劳寿命。一般100Hz频率下测试1010次循环试验需要3.2年,使用本机进行试验只需要6天。
· 可以简单地再现微小缺陷而产生的疲劳破坏。
· 由于在共振状态下进行试验,可以产生高应力,能够进行1000MPa级的钢材试验。另外,功耗小非常经济。
· 采用计算机设定和控制试验。在桌面上进行试验。

 规 格:

· 试验频率:20kHz±500Hz
· 试验应力范围:缺口断面公称应力100~500MPa
          🅷       圆锥中央称应力180~900MPa

 用 途:

适合金属材料107~1010循环的长寿命疲劳极限测试。
