Embodiment Construction
[0028] The present invention will be further explained below in conjunction with the accompanying drawings.
[0029] Such as figure 1 The fatigue test device for the main force transmission structure during the ejection process of the landing gear is shown, including the ejection rod 1, the rotating sleeve 2, the upper torque arm 3, the lower torque arm 4, the ejection load loading mechanism, the pinning load loading mechanism and the main force transmission mechanism. Device fixing mechanism. It also includes two vertical beams 5 arranged oppositely, and an upper beam 7 and a lower beam 8 are respectively arranged along a direction perpendicular to the vertical beams 5 . The top of the vertical beam 5 is also provided with a top beam 6 for fixing.
[0030] Such as figure 2 As shown, the vertical beam structure is supported by fixed brackets 13 . The fixed support 13 is a triangular support, which is provided with 2 groups, which are respectively arranged on both sides of...
