The invention belongs to the technical field of aviation aircraft ground tests, and relates to a multi-component load condition synchronous implementation test design method and device, and the method comprises the steps: S1, determining whether the component load condition can be trimmed or not; s2, when the component load working condition cannot be balanced, whether other component load working conditions capable of being subjected to stress decoupling with the component load working condition exist or not is determined; s3, when two component load working conditions capable of performing stress decoupling exist, determining the main force element direction and magnitude of each component load working condition; s4, when the main force elements are opposite in direction, the load difference of simultaneous implementation of the load working conditions of the two parts is determined according to the magnitude; and S5, when the load difference is smaller than a preset load threshold value, it is determined that the load working conditions of the two parts can be synchronously implemented, a combined working condition is formed, and load balancing of other parts of the aircraft is conducted according to the load difference of the combined working condition. According to the invention, the magnitude of the balancing load can be obviously reduced, and the design difficulty of the test load is reduced.
本申请属于航空飞行器地面试验技术领域,涉及一种多部件载荷工况同步实施试验设计方法及装置,该方法包括:步骤S1、确定部件载荷工况是否能够被配平;步骤S2、当部件载荷工况不能被配平时,确定是否存在能与其进行应力解耦的其他部件载荷工况;步骤S3、当存在能够进行应力解耦的两个部件载荷工况时,确定各部件载荷工况的主力素方向和量级;步骤S4、当主力素方向相反时,根据量级确定这两个部件载荷工况同时实施的载荷差;步骤S5、当载荷差小于预设的载荷阈值时,确定这两个部件载荷工况能够同步实施,形成组合工况,并根据组合工况的载荷差进行飞机其他部件的载荷配平。本申请可显著减小配平载荷的量级,降低了试验载荷设计难度。
