Two of the tests, known as the impact resistance test and the fatigue test
, are designed to establish the risk of them being dislodged by children rattling, shoving or kicking them.
In October 2018 it found that three stair gates failed the fatigue test
A prototype fatigue test
for the slab track was carried out during winter in a cold region of north-east China.
In this paper, the constant amplitude fatigue test
was applied to research the fatigue life of rocklike fractured specimens, and the suitable fatigue life models were selected.
In this study, as-cast miniature size specimens were used for the tensile test and the low cycle fatigue test
The first set of beams was subjected to the static test up to failure, and the fatigue test
at the low cycle was conducted on the second set of beams for the evaluation of the fatigue performance.
Currently the fatigue test
of the compressor blades mainly includes the resonance fatigue test
and the ultrasonic fatigue test
, in which the ultrasonic fatigue test
also uses the ultrasonic transducer to resonate the specimen.
The evolution of the sentry function during the cyclic fatigue test
shows a part (part I.b) where the function is decreasing significantly.
Assuming a safety factor of 1.5, 1500 repeats of each individual fatigue test
were performed to simulate the actual clinical rehabilitation process.
