Abstract
A multiaxial fatigue machine comprising a rotational mechanism; a driven shaft arranged collinearly with a first power shaft of the rotational mechanism and a reciprocating mechanism. The rotational mechanism has a first motor and a first fastening element configured to be connected to a test element that can be also connected to a second fastening element of the driven shaft to transmit to said test element a rotational force produced by the first motor. The reciprocating mechanism has a second power shaft, a second motor, and a linear rotational transmission, wherein the reciprocating mechanism is configured to apply an alternating force on the test element.
Claims10
A multiaxial fatigue machine comprising:
- a rotational mechanism comprising:
- a first power shaft with
- a first end connected to a first motor by a first coupling element;
- and
- a second end connected to a first fastening element;
- a driven shaft arranged collinearly with the first power shaft, the driven shaft comprising
- a first end connected to a fixed bearing;
- a second end connected to a second fastening element,
- where the second fastening element is arranged collinearly
- with the first fastening element;
- and
- a second coupling element connecting the first end to
- the second end;
- a reciprocating mechanism comprising:
- a second power shaft connected to a second motor;
- and
- a linear rotational transmission connected to the second power shaft,
- wherein the first fastening element and the second fastening element are configured to be connected to a test element and transmit to said test element a rotational force produced by the first motor, and
- wherein the second power shaft is configured to transfer power from the second motor to the linear rotational transmission in order to apply an alternating force on the test element.
