The invention relates to a fatigue test device for an outer front flap and joint test piece. The device comprises: an integral test bench; a pulley seat assembly supporting structure, an actuator cylinder fixing cross beam and a lever support supporting structure which are fixed on the test bench; a test piece supporting structure which is fixed on the test bench; a front joint loading mechanism which can apply a load to the front joint through a front joint loading actuator cylinder and a lever; and a rear joint loading mechanism which can apply a lateral load to a rear joint through a lateral loading actuator cylinder, can apply a course load to the rear joint through a course loading actuator cylinder, and can convert the applied vertical load into the course load to the rear joint through a vertical loading actuator cylinder and a pulley. According to the invention, the fatigue test function and loading requirements of the outer front flap and the joint can be met, effective test piece boundary condition simulation is carried out, and the rigidity and strength requirements of the test are met.

    本申请涉及一种用于外前襟翼及接头试验件的疲劳试验装置,所述装置包括:整体式的试验台架;固定在试验台架上的滑轮座组件支撑结构、作动筒固定横梁和杠杆支座支撑结构;固定在试验台架上的试验件支持结构;前接头加载机构,其通过前接头加载作动筒和杠杆能够施加载荷于前接头;后接头加载机构,其通过侧向加载作动筒能够施加侧向载荷于后接头、通过航向加载作动筒能够施加航向载荷于后接头以及通过垂向加载作动筒及滑轮能够将施加的垂向载荷转化为航向载荷于后接头。本申请能够满足外前襟翼及接头疲劳试验功能和加载要求,进行了有效的试验件边界条件模拟,满足试验要求刚度和强度要求。
