Abstract

The invention discloses a laboratory-use abruptly increased high-energy basic excitation test bench, which comprises an air cannon, a base, a test bench top supported on the base, a simulated engine and a drive motor installed on the test bench top; The platform is connected by plate springs or ordinary multi-directional springs; when the air cannon and plate spring are installed on the side of the test bench, it is a sudden lateral high-energy basic excitation test bench, which can be used to simulate the near field / far field of marine gas turbines. The working condition of sudden lateral high-energy foundation excitation during field explosion; when the air cannon system and leaf spring are installed in the axial direction of the test bench, the axial high-energy foundation excitation test bench is suddenly added, which can be used to simulate the sudden impact of the aviation gas turbine when arresting the landing. The working condition of adding axial high-energy foundation excitation.

Description

technical field [0001] The invention relates to the field of gas turbine engines, in particular to a test bench and a test method for a gas turbine engine complete machine or rotor parts subjected to sudden high-energy basic excitation. Background technique [0002] Taking carrier-based aircraft and aircraft carriers as examples, under service conditions, aviation gas turbine engines may encounter blocking landings, and marine gas turbines may encounter near-field / far-field explosions. The sudden high-energy load formed in the engine structure under the above-mentioned severe working conditions acts on the engine in the form of high-density impact energy, which may cause deterioration of the dynamic characteristics of the entire engine / rotor components and damage to key structures, jeopardizing the safety of the engine structure. affect its safety. [0003] According to the characteristics of the load action, the research on the dynamic response of the gas turbine engine un...
