ABSTRACT:
A device for testing the fatigue vibration strength consists of a framework carrying a spring-mounted vibrating body, an electromagnetic exciter arranged between the vibrating body and one holding element to hold the test body. There is also an adjustable threaded spindle for the purpose of superimposing a static load on the vibrating load affecting a test body during a vibration strength test. The exciter is provided with two parts which are movable in relation to one another, the one part being connected to the vibrating body and the other to the aforementioned holding element. The two exciter parts are connected to one another by elastic rod shaped members. These are dimensioned in such a manner that in all foreseen operating conditions an air gap remains between the exciter parts permitting vibration excitation with good efficiency.
