The invention belongs to the technical field of aviation structure design, and particularly relates to a test piece for verifying influence of assembly stress on service life. Comprises: a test piece having a region of interest and a loading region; the installation part is provided with a region of interest and a loading region; wherein the region of interest of the test piece and the region of interest of the mounting piece are assembled through a fastener, and an assembly gap is formed at the assembly position; the loading area of the test piece and the loading area of the installation piece are used for applying loads. The test piece for verifying the influence of the assembly stress on the service life is simple and efficient in structural form, the process is easy to implement, and the production period is short; different test piece loading schemes are selected according to the loading form of a test piece, and structural assembly under different gap values is achieved by replacing mounting pieces; ins
