Abstract

The present invention discloses a mouse cage elastic supporting device vibration strain and amplitude calibration system and method. The mouse cage elastic supporting device vibration strain and amplitude calibration system comprises an excitation system connected with a simulation shaft and used for generating an excitation force and applying the generated excitation force on the simulation shaft; a test article installing rack used for installing the simulation shaft and a to-be-calibrated mouse cage elastic supporting device and transmitting the excitation force applied by the excitation system to the to-be-calibrated mouse cage elastic supporting device via the simulation shaft; and a monitoring system connected with the to-be-calibrated mouse cage elastic supporting device and used for recording the cage bar vibration strain and the bearing block outer ring amplitude of the to-be-calibrated mouse cage elastic supporting device under the excitation force. The mouse cage elastic supporting device vibration strain and amplitude calibration system and method of the present invention is simple to operate and convenient to assemble and disassemble, simulates the working state of the mouse cage elastic supporting device really, can be suitable for the strain and amplitude calibration of different types of mouse cage elastic supporting devices, avoids the situation that the mouse cage elastic supporting device is carried out the calibration test on a test bench, and enables a lot of manpower and material resource waste to be reduced.

Description

technical field [0001] The invention relates to the field of aero-engines, in particular to a vibration strain and amplitude calibration system and method for a squirrel cage elastic support. Background technique [0002] In the development process of small and medium-sized aero-engines, it is an important special vibration testing technology to ensure the safe and reliable operation of the compressor and turbine in the performance test through the vibration strain monitoring of the squirrel cage elastic support. In the prior art, the empirical formula is often used To calculate the relationship between the vibration strain ε at the root of the cage bar of the squirrel cage elastic support and the amplitude y of the outer ring of the bearing seat of the squirrel cage elastic support, so as to determine the vibration strain limit value of the squirrel cage elastic support, where h in the empirical formula is The thickness of the cage bar, l is the length of the cage bar, an...
