Abstract

The invention discloses a rotor blade damping block reliability test method, and relates to the technical field of engine testing. The rotor blade damping block reliability test method comprises the following steps that S1, a pressure load F2 is applied to the first side surface (11) of a test damping block (1), wherein the direction of the pressure load F2 is perpendicular to the first side surface (11); the pressure load is applied in a graded way, and each grade of load is increased for 10% of F2 than the last grade of load until the pressure load reaches the value of F2; and S2, a vibration load T is applied to the first side surface (11) of the test damping block (1). The beneficial effects of the rotor blade damping block reliability test method are that reliability testing can be independently performed on the damping block of a rotor blade without being performed along with testing of the complete engine so that the test method is simple, the test period is short and the test cost is low.

Description

technical field [0001] The invention relates to the technical field of engine testing, in particular to a reliability testing method for a rotor blade damping block. Background technique [0002] Adding a rubber damping block under the edge plate of the rotor blade is an effective way to suppress the vibration of the blade. At present, the reliability verification of the damping block needs to be carried out with the test run of the whole engine, which takes a long time and requires a lot of investment, especially for civil engines, which require more than 10,000 hours of service life for cold-end components (including the damping block). Contents of the invention [0003] The purpose of the present invention is to provide a reliability test method for a rotor blade damping block, so as to solve or at least alleviate at least one problem existing in the background art. [0004] The technical solution adopted in the present invention is to provide a reliability test method...
