Traction and compression fatigue test bench
Reference
: MFTC
Technical description
Main functions
The testing machines allow to estimate the fatigue life of components and/or finished products. Fatigue tests characterize the ability of a material or product to withstand cyclical loading in order to best reproduce the operating conditions of the part.
The traction/compression fatigue test bench allows to subject parts to tensile/compression stress according to slow or rapid cycling (fatigue tests).
Operating mode
After positioning the part to be tested, the user defines a test program, consisting of a sequence of function blocks.
Each function performs trapezoidal or sinusoidal cycles controlled in force or position at an adjustable frequency.
The test is stopped automatically in the case of a rupture of the tested part.
