Abstract

The invention provides an aircraft engine casing static test method and a testing assembly thereof. The method comprises the following steps of: assembling a plurality of casings to be tested to form the testing assembly according to an actual assembly requirement of an aircraft engine; fixing the testing assembly; applying simulation load to the testing assembly; and testing according to preset testing items. In the provided test method, the casings of the aircraft engine are combined for testing, mutual influence among the plurality of casings is considered, the load transmission among the casings is more truly simulated in the process of operating the aircraft engine, tested conclusion is more true and reliable, the test period can be effectively shortened by about 2 / 3, and the cost ofscientific research is reduced.

Description

technical field [0001] The invention relates to the field of aero-engines, in particular to a static test method for an aero-engine casing and a test assembly for implementing the method. Background technique [0002] The load-bearing parts of the casing are the main components of the engine load-bearing system, and the accuracy of design analysis in this aspect directly affects the durability and reliability of the aero-engine. [0003] In order to verify whether the casing meets the requirements of the engine, it is necessary to conduct a static test on the casing. However, the investigation and understanding of domestic scientific research institutes and related domestic literature have found that the tests of casing-like load-bearing parts are all tested with a single casing. On the one hand, this test method requires correct load calculation and accurate test boundary conditions. On the other hand, the interaction between parts cannot be simulated during the test.
