Problems solved by technology

There are many limitations in the traditional special-purpose analysis software. In addition to poor popularization and applicability, the traditional calculation method has a high amount of model simplification and relatively large calculation deviations, and can only perform calculations under the critical speed of the rotor without bearing constraints and the simple harmonic load. Kinetic calculation
With the wide application of large-scale general finite element analysis software, the purpose of the present invention is to provide a calculation method based on ANSYS finite element calculation software for the torsional vibration of the reciprocating compressor rotor system, to solve the problem of restricting the reciprocating compressor to multi-row, high-speed The technical bottleneck of development

Abstract

The invention discloses a design method for torsional vibration of a reciprocating compressor rotor system, and the method comprises the steps of carrying out the mass equivalent calculation on a moving part of a reciprocating compressor, and providing data for the model conversion of a torsional vibration system of the reciprocating compressor rotor system, wherein the reciprocating compressor moving part for mass equivalent calculation comprises a connecting rod, a crosshead and a piston; and according to the principle that the rotational inertia of the structure is equal, carrying out equivalent processing on a coupler structure, a flywheel and a motor rotor structure of the rotor system, thereby completing the geometric model construction of the reciprocating compressor rotor system comprising a crankshaft, the equivalent coupler, the equivalent flywheel, a motor shaft and a equivalent motor rotor; and using the general ANSYS finite element calculation software for replacing the original special analysis software, so that the calculation precision and the working efficiency of the torsional resonance of the reciprocating compressor rotor system are improved, and the method is not limited by the proprietary technical attribution of reciprocating compressor series products and can be widely applied in the industry.

Description

technical field [0001] The invention relates to the field of rotor dynamics calculation of a reciprocating compressor, in particular to a design method for torsional vibration of a rotor system of a reciprocating compressor. Background technique [0002] The calculation technology of the torsional vibration of the rotor system of the reciprocating compressor is the technical bottleneck restricting the development of the reciprocating compressor to multi-column or high speed. A large number of studies have shown that the more columns of the reciprocating compressor rotor system, the lower the torsional natural frequency of the system, and the easier it is for the unit to resonate; the higher the speed of the reciprocating compressor, the greater the torsional load that causes system resonance, and the easier it is for the unit Resonance occurs. [0003] The calculation of the torsional vibration of the reciprocating compressor rotor system usually uses traditional special an...
