Abstract

The invention provides a multifunctional rotor test bench which comprises a shafting misalignment fault simulation mechanism, a moving-static-rub-impact simulation mechanism. The shafting misalignment fault simulation mechanism comprises a motor rotary table, two bearing seats supporting a rotor and a coupler. The motor rotary table is arranged on a base and can drive a motor to rotate by a certain angle. The two bearing seats can drive the rotor to move in the radial direction. The moving-static-rub-impact simulation mechanism comprises a stepped turn plate and a rub-impact frame. The rub-impact frame and the stepped turn plate are adjustable in the axial direction, the stepped turn plate and the rotor are fixed, the rub-impact frame and the base are fixed, the stepped turn plate is provided with a detachable rub-impact bar, and the rub-impact frame is provided with a spring plate and an eddy-current sensor. The coupler comprises a motor end flange disc, a rotor end flange disc and an adjusting block arranged between the motor end flange disc and the rotor end flange disc, and the adjusting block is selected to be used according to simulation states. The multifunctional rotor test bench has the advantages of being multiple in function, wide in application range, and visual in test process, and filling the blank of mechanical rotor composite fault simulation.

Description

technical field [0001] The present invention relates to an experimental equipment, in particular, it can simultaneously simulate different degrees of shaft misalignment faults, dynamic and static rubbing faults, mass unbalance faults, and composite faults composed of any two or three of these three faults. Multifunctional rotor test bench. Background technique [0002] Rotating machinery rotors often have some faults during the rotation process, such as misalignment of the shaft system, dynamic and static rubbing, and mass imbalance. Shaft misalignment refers to the fact that the centerlines of two adjacent rotors are not in a straight line, that is, tilted or offset. Misalignment is divided into parallel misalignment, offset angle misalignment, and parallel and offset angle misalignment at the same time. Dynamic and static rubbing refers to the collision and friction between rotating parts and stationary parts, which can be divided into partial rubbing and full-circle rub...
