控制臂疲劳试验机 
Control Arm Test System
The series-accompanying test of axle components, e.g. wishbones, control-arms, is executed on
component specific resonance test systems. Advantages of these systems are the extremely low
energy consumption, the high test frequencies, the small maintenance costs and the exact automatic
incipient crack recognition.
The wishbone test system is designed as an electromagnetic resonance test system with a free
standing magnet drive. This drive is extremely versatile applicable, e.g. for a module supports. The
electromagnets are built in a Push-Pull arrangement, so large forces are also available with high
frequencies. The installation of the test system takes place on a horizontal span with 2.000 x 27 x
1.000 mm. Thereby the dynamic drive and the sample can be arranged variably. The dynamic uncoupling
is part of the scope of supply. The test frequency can be changed by the provided additional
masses.
