用于测定疲劳极限的电液伺服疲劳试验机

电液伺服疲劳试验机在材料和部件试验有很广泛的应用，其用周期或随机信号可执行脉冲或交变载荷。很容易得到准静态-静态和动态载荷。

ZwickRoell具备各种各样的材料试验机，适用于部件或产品的疲劳极限测试。产品范围从单试验作动缸到电液伺服疲劳试验机，适用于多轴疲劳试验，可用的试验载荷范围从5至2500 kN。ZwickRoell还提供Vibrophore高频疲劳试验机可测定疲劳强度。疲劳极限的测定可通过部件的拉伸和压缩极限及扭转极限

ZwickRoell疲劳极限试验概览

ZwickRoell提供一个单独的定制的模块化的系统可满足所有测定疲劳极限的测试要求。系统包含作动缸，液压动力源，分配器，动态试验机和其他附件。在试验机旁边有强大的测量和控制器testControl II，ZwickRoell testXpert II测试软件在设置和执行动态试验时为其提供支持。除了标准产品，还有单独的定制的疲劳试验解决方案。

Servohydraulic Testing Machines

Servohydraulic testing machines from ZwickRoell can be used for fatigue limit testing.

High-Speed Testing Machines

The high-speed testing machines are ideal for puncture tests or high-speed tensile tests.

The HTM series high-speed testing machines are ideally suited for the determination of material behavior under crash loading.
