Selection of Plate Self-Locking Nut

Abstract:

Through the correct assembly of various types of Plate Self-Locking Nuts, and their related mechanical properties test, on the premise of that Floating Two Lug Plate Self-Locking Nu, Floating Plate Self-Locking Nut, Cherry Rivetless Self-Locking Nut Plate, and Retainer Rivetless Plate Self-Locking Nut can satisfy the procurement specifications, use the same load levels on above four kinds of Plate Self-Locking Nuts to implement resisting shear connectors fatigue comparison test, and provide the basis for the selection of the Rivetless Plate Self-Locking Nut and its utilization in aircraft fatigue critical region. The results show that with the experimental study of four kinds of plate floating self-locking nut, the overall performance is relatively good to Floating Plate Self-Locking Nut and Retainer Rivetless Plate Self-Locking Nut, both of the two kind of Self-Locking Nuts plate can meet the requirements of the mechanical properties to Plate Self-Locking Nut, and their fatigue performance is greatly improved as opposed to the Floating Two Lug Plate Self-Locking Nut. Since the studied Plate Self-Locking Nuts are already used to aircraft in a larger amount, the study could be applied to various aircraft design and selection of the Plate Self-Locking Nut.
