Dynamic and coupled vibration analysis of an axial piston pump swashplate with localized imperfections involves studying the behavior of the swashplate under operating conditions while taking into account the presence of imperfections. Here is an overview of the analysis process: 1. Geometric and material modeling: Create a detailed geometric model of the swashplate, including its dimensions, features, and local defects. Define the material properties of the swash plate, such as elasticity, density, and damping coefficient. 2. Boundary conditions: Determine the boundary conditions that represent the operating conditions of the pump, such as applied pressure, fluid flow rate, and rotational speed. These conditions will affect the dynamic response and vibration behavior of the swashplate. 3. Finite element modeling: using finite element analysis (FEA) software to discretize the swash plate model into smaller finite elements. Assign appropriate element types, mesh sizes, and attributes to accurately represent the behavior of the swashplate. 4. Static analysis: Static analysis is performed to determine the deformation and stress distribution of the swash plate under the applied load. This analysis determines the initial state of the swashplate before considering dynamic effects. 90-L-250-KA-5-EG-80-S-3-C8-K-00-NNN-35-14-30-G005 90L250KA5EG80S3C8K00NNN351430G005 90L250-KA-5-EG-80-S-3-C8-K-03-NNN-35-35-24 90L250KA5EG80S3C8K03NNN353524 90-L-250-KA-5-EG-80-S-3-C8-K-03-NNN-35-35-24 90L250KA5EG80S3C8K03NNN353524 90L250-KA-5-EG-80-S-3-C8-K-03-NNN-42-42-24 90L250KA5EG80S3C8K03NNN424224 90-L-250-KA-5-EG-80-S-3-C8-K-03-NNN-42-42-24 90L250KA5EG80S3C8K03NNN424224 90L250-KA-5-EG-80-S-4-C8-J-03-NNN-30-30-24 90L250KA5EG80S4C8J03NNN303024 90-L-250-KA-5-EG-80-S-4-C8-J-03-NNN-30-30-24 90L250KA5EG80S4C8J03NNN303024 90-L-250-KA-5-EG-80-T-3-C8-J-03-NNN-35-35-24 90L250KA5EG80T3C8J03NNN353524 90L250-KA-5-EG-80-T-3-C8-K-03-NNN-26-26-24 90L250KA5EG80T3C8K03NNN262624 90-L-250-KA-5-EG-80-T-3-C8-K-03-NNN-26-26-24 90L250KA5EG80T3C8K03NNN262624 90L250-KA-5-EG-80-T-4-C8-J-03-NNN-26-26-24 90L250KA5EG80T4C8J03NNN262624 90-L-250-KA-5-EG-80-T-4-C8-J-03-NNN-26-26-24 90L250KA5EG80T4C8J03NNN262624 90L250-KA-5-NN-80-S-3-C8-K-03-NNN-30-30-24 90L250KA5NN80S3C8K03NNN303024 90-L-250-KA-5-NN-80-S-3-C8-K-03-NNN-30-30-24 90L250KA5NN80S3C8K03NNN303024 90L250-KA-5-NN-80-S-3-C8-K-03-NNN-32-32-24 90L250KA5NN80S3C8K03NNN323224 90-L-250-KA-5-NN-80-S-3-C8-K-03-NNN-32-32-24 90L250KA5NN80S3C8K03NNN323224 90L250-KA-5-NN-80-S-3-C8-K-03-NNN-32-32-28 90L250KA5NN80S3C8K03NNN323228 90-L-250-KA-5-NN-80-S-3-C8-K-03-NNN-32-32-28 90L250KA5NN80S3C8K03NNN323228 90L250-KA-5-NN-80-S-3-C8-K-03-NNN-35-35-24 90L250KA5NN80S3C8K03NNN353524 90-L-250-KA-5-NN-80-S-3-C8-K-03-NNN-35-35-24 90L250KA5NN80S3C8K03NNN353524 5. Modal analysis: Modal analysis is performed to determine the natural frequency, mode shape and corresponding vibration mode of the swash plate. This analysis helps identify critical frequencies that may excite resonance and cause excessive vibration. 6. Dynamic analysis: Apply dynamic loading conditions to the swash plate model to simulate the forces and moments generated during pump operation. Consider fluid pressure distribution, rotational motion, and interactions between the swashplate and other pump components. 7. Coupled vibration analysis: Study the coupling vibration effect between the swash plate and other components (such as bearings, pistons or valve plates). Analyze how vibrations propagate through the pump structure and how they potentially affect the performance and reliability of the swashplate. 8. Defect analysis: Introduce local defects in the swash plate model, such as surface irregularities, cracks or material discontinuities. Evaluate the impact of these imperfections on the dynamic behavior of the swashplate, including changes in natural frequencies, mode shapes, and stress concentrations. 9.
