Skin butt joint connection strength determination method and device based on temperature influence

Abstract

The invention belongs to the technical field of airplane static strength design, and particularly relates to a skin butt joint connection strength determination method and device based on temperature influence. The method comprises the following steps: reading a mechanical response file under each industrial control of a structure and a node temperature field file of the structure; data in the mechanical response file and the node temperature field file are extracted, a preset butt joint part unit force array is assigned, the butt joint part unit force array is a two-dimensional array, the first dimension in the two-dimensional array is a connection part, and the second dimension at least comprises a structure parameter, a mechanical parameter, a temperature parameter and a working condition number; calculating the shearing margin of the connection part of each working condition; and the connecting part shearing margins of all the connecting parts under the multiple working conditions are sequenced, and the minimum margin value, the corresponding working condition number and the mechanical parameter are assigned to a preset minimum margin array. According to the method, the accuracy and the working efficiency of static strength calculation of the skin butt joint connection part under the high-temperature condition are improved.
