Abstract

The invention provides a falling off test rotor assembly and a releasing method for the same. The releasing method comprises steps of separating a connection structure of the rotor assembly which needs to be released from the rotor assembly, using a remaining part of the rotor assembly as a rotor flying-off part, using explosive bolts to connect the rotor flying-off part and the connection structure, detonating explosives built in the explosive bolts under a regulated rotation speed of the rotor in the process of the falling off test, and destroying a bearing capacity of the explosive bolts in order to release the flying-off part of the rotor of the rotor assembly which is connected. The falling off test rotor assembly and the releasing method for the same can effectively improve releasing rotation speed control accuracy, reduce influence on the flying-off posture and flying-off kinetic energy of the rotor assembly, improve convenience and reliability of installation of the releasing device and can reduce the danger in the whole testing process.

Description

technical field [0001] The invention relates to the technical field of rotating machinery, in particular to a rotor assembly and a release method thereof during a shedding test. Background technique [0002] During the operation of high-speed rotating machinery, the shedding of rotor components often poses a huge threat to the safety of personnel and property. Therefore, before any rotating machinery leaves the factory, a rotor assembly drop-off test must be carried out to verify the machinery's ability to tolerate flying out of rotating parts at high speeds. [0003] In the prior art, two methods are usually used to artificially control the release timing of the rotor assembly during the test. The first method is the prefabricated crack method. In this method, artificial prefabricated partial cracks are set at the designated parts of the test piece. Due to the centrifugal load of the rotor assembly, the prefabricated cracks expand at a certain rotor speed and cause the joi...
