Description

[0001] Technology field

[0002] This invention relates to the field of precision equipment assembly technology, and particularly to the field of precision assembly technology for large-scale high-speed rotary equipment. Background Technology

[0003] Many large high-speed rotary equipment pieces are composed of multi-stage rotor assemblies, and the precision of these assemblies has a crucial impact on their performance. The imbalance of each rotor stage after assembly is a key parameter for evaluating the assembly quality of large high-speed rotary equipment. Significant imbalance at each rotor stage directly leads to severe vibrations during operation, potentially causing malfunctions. Furthermore, imbalance generates substantial radial forces, causing bearing wear and reducing bearing lifespan, and also generates torque that can cause bending of the rotation axis. Therefore, reducing the rotor imbalance after multi-stage rotor assembly is extremely important for suppressing vibrations and extending the lifespan of large high-speed rotary equipment. Establishing an imbalance transfer model for multi-stage rotor stacking assemblies can guide assembly and avoid the problem of repeated disassembly and reassembly due to excessive imbalance at each rotor stage. Existing imbalance prediction models for multi-stage rotor stacking assemblies can predict the imbalance at each rotor stage after assembly, but due to a lack of consideration for the actual assembly process, they lack a certain degree of realism in guiding assembly.

[0059] Existing large-scale high-speed rotary equipment generates imbalance after assembling each stage of the rotor. Significant imbalance at each stage directly leads to severe vibration during operation, potentially causing equipment malfunction. This embodiment provides a method for stacking imbalance in large-scale high-speed rotary equipment based on a reference transformation. This method obtains an imbalance control model for the rotary equipment, and assembly is performed according to this model to solve the problem of imbalance after assembling each stage of the rotor, thus preventing equipment malfunction.

[0060] Existing large-scale high-speed rotary equipment generates imbalance after assembling each stage of rotor. This imbalance produces significant radial forces, leading to bearing wear and reduced bearing life. It also generates torque that causes bending of the rotation axis.

This embodiment provides a method for stacking imbalance in large-scale high-speed rotary equipment based on reference transformation. Building upon the original stacking model, it considers the pose transformation from the actual reference to the ideal reference. The imbalance obtained according to the actual reference is closer to the actual imbalance during actual operation and possesses scientific validity.

For example, the size of the centroid of the bladed disk Represented as:

[0068]

[0069] Implementation Method 5. This implementation method addresses the imbalance quantity Q in step S4 of the imbalance quantity stacking method for large high-speed rotating equipment based on reference transformation described in Implementation Method 1. i For example, the imbalance quantity Q i Represented as:

[0070] Where: mBijk is the mass of the k-th blade at the j-th section of the i-th stage rotor, mDi is the mass of the i-th stage bladed disk, and nij is the total number of blades at the j-th section of the i-th stage rotor. Let be the size of the centroid of the i-th stage bladed disk. Let be the centroid size of the k-th blade in the j-th layer of the i-th stage rotor.

[0071] This implementation method obtains unbalanced excitation. In order to ensure the working requirements of the rotor, dynamic balancing is required to eliminate these unbalanced excitations.

[0072] Implementation Method Six. This implementation method illustrates the vector of the unbalanced excitation at position A in step S5 of the unbalanced quantity stacking method for large high-speed rotating equipment based on reference transformation described in Implementation Method One. The vector representation of the unbalanced excitation at position A is as follows:

[0073]

[0074] Among them: Z B To correct the coordinates of plane B on the Z-axis of the coordinate system, Z... A To correct the coordinates of surface A on the Z-axis of the coordinate system, Z... i Let be the coordinates of the i-th stage rotor section on the Z-axis of the coordinate system.

[0075] In practical applications, to ensure the rotor's operational requirements, dynamic balancing is necessary to eliminate unbalanced vibrations. Dynamic balancing involves installing mass blocks on a selected calibration surface. Here, surface A is the selected calibration surface. By projecting the unbalanced vibration vector onto surface A, we can determine the location and weight of the mass block needed to eliminate the unbalance.

[0076] Implementation Method Seven. This implementation method illustrates the vector of the unbalanced excitation at position B in step S5 of the unbalanced quantity stacking method for large high-speed rotating equipment based on reference transformation described in Implementation Method One. The vector representation of the unbalanced excitation at position B is as follows:

[0077]

[0078] Among them: Z B To correct the coordinates of plane B on the Z-axis of the coordinate system, Z... A To correct the coordinates of surface A on the Z-axis of the coordinate system, Z... i Let be the coordinates of the i-th stage rotor section on the Z-axis of the coordinate system.

[0079] In practical applications, to ensure the rotor's operational requirements, dynamic balancing is necessary to eliminate unbalanced vibrations. Dynamic balancing involves installing mass blocks on a selected calibration surface. Here, surface B is the selected calibration surface. By projecting the unbalanced vibration vector onto surface B, we can determine the location and weight of the mass block needed to eliminate the unbalance.

[0080] Implementation Method Eight. This implementation method illustrates step S6 of the imbalance stacking method for large high-speed rotating equipment based on reference transformation described in Implementation Method One, where reference transformation model A is represented as follows:

[0081]

[0082] Where: l is the direction vector of the rotation axis, w is the unit vector of the direction vector of the rotation axis, and θ is the rotation angle.

[0083] In practical applications, the reference axis for calculating the imbalance using traditional stacking methods is an ideal rotation axis, i.e., the Z-axis of a coordinate system centered at point O on the lower end face of the first-stage rotor. However, during the operation of an aero-engine, the actual rotation axis is centered at the center O of both the lower end face of the first-stage rotor and the upper end face of the highest-stage rotor. nA Connect the lines. For example... Figure 4 As shown, therefore, based on the original stacked model, it is necessary to consider the pose transformation from the actual reference to the ideal reference to obtain the coordinates of the centroid of each rotor in the coordinate system OX′Y′Z′. The coordinate system OX′Y′Z′ can be regarded as the coordinate system OXYZ being obtained by rotating θ around the rotation axis containing the origin O. Let the rotation axis direction vector l be (lx, ly, lz)T, and the unit vector of this vector is... The center O of the upper end face of the highest grade rotor nA The position vector in the coordinate system OXYZ with the ideal reference as the Z-axis is P(O nAx O nAy O nAz ) T In a coordinate system OX′Y′Z′ with the actual reference as the Z-axis, the position vector can be represented as Q(0,0,O). nAz ') T Then the rotation axis direction vector l and the rotation angle θ are:

[0084]

[0085]

[0086] The reference transformation matrix A can be obtained from the direction vector l and the rotation angle θ.

[0087] Implementation Method Nine. This implementation method illustrates the unbalance control model of the slewing equipment in step S7 of the unbalance stacking method for large high-speed slewing equipment based on reference transformation described in Implementation Method One. The unbalance control model of the slewing equipment is expressed as follows:

[0088]

[0089]

[0090] Wherein: QAx, QAy, and QA are the components of the unbalance projected onto the correction surface A in the X, Y, and Z axes without considering the reference transformation; Q′Ax, Q′Ay, and Q′Az are the components of the unbalance projected onto the correction surface A in the X, Y, and Z axes with considering the reference transformation; QBx, QBy, and QBz are the components of the unbalance projected onto the correction surface B in the X, Y, and Z axes without considering the reference transformation; and Q′Bx, Q′By, and Q′Bz are the components of the unbalance projected onto the correction surface B in the X, Y, and Z axes with considering the reference transformation.

[0091] In practical applications, to ensure the rotor's operational requirements, dynamic balancing is necessary to eliminate unbalanced vibrations. Dynamic balancing involves installing mass blocks on selected calibration surfaces (A and B are the selected calibration surfaces). By projecting the unbalanced vibration vector onto surfaces A and B, it becomes possible to determine the appropriate position and weight of the mass blocks on surfaces A and B to eliminate the unbalance. Therefore, dynamic balancing can be guided by an unbalanced control model for rotating equipment.
