The invention discloses a thermal stress equivalent applying device for an aircraft mechanical connection structure. The device comprises a mechanical connection structure test piece, a first stress applying unit and a second stress applying unit, the mechanical connection structure test piece comprises a mechanical connection piece and a plurality of connection bolts; the first stress applying unit comprises a first guide rod and a first adjustable load applying structure; the second stress applying unit comprises a second guide rod and a second adjustable load applying structure; the first adjustable load applying structure is arranged on the front side of the connecting bolt, and the second adjustable load applying structure is arranged on the rear side of the connecting bolt. By arranging the first stress applying unit and the second stress applying unit, stress can be applied to the two sides of the connecting bolt at the same time, and equivalent thermal stress is equivalently applied to the connecting bolt; dispersed thermal stress is equivalent to one equivalent connecting bolt through the equivalent applying device, and the difficulty and the test period of the test are greatly reduced.

    本发明公开了一种飞机机械连接结构热应力等效施加装置,该装置包括机械连接结构试验件、第一应力施加单元、以及第二应力施加单元;机械连接结构试验件包括机械连接件和多个连接螺栓;第一应力施加单元包括第一导杆和第一可调节载荷施加结构;第二应力施加单元包括第二导杆和第二可调节载荷施加结构;第一可调节载荷施加结构布设在该连接螺栓的前侧,第二可调节载荷施加结构布设在该连接螺栓的后侧。本发明通过设置第一应力施加单元和第二应力施加单元,可同时对连接螺栓的两侧施加应力,等效对连接螺栓施加同等的热应力;通过本等效施加装置将分散的热应力等效在一个等效连接螺栓上,大大降低该类试验开展的难度和试验周期。
