<p>The present invention provides a fatigue test apparatus for a membrane. According to the present invention, the fatigue test apparatus for a membrane comprises: first to fourth fixating parts separately fixated with first to fourth fixating surfaces which are partitioned by ribbed parts crossing each other in the membrane of a cargo hold; a driving part for moving the first and third fixating parts facing each other in a first direction and in the opposite direction, respectively in order to alternately apply a tensional force and a compressive force to the membrane; and an out-of-plane deformation preventing member for connecting the fourth fixating part to the second fixating part facing the fourth fixating part.</p> |
