Stress analysis and parameter optimization of air conditioning outdoor unit pipeline
his paper investigates the pipeline system in the outdoor unit of an air conditioner to solve the problem of the pipeline system with a large stress at the operation speed of 60Hz.Based on the finite element model and the modal analysis,the natural frequency and vibration mode of the pipeline can be calculated.The radial force,torque excitation and the pressure pulsation in the pipeline are used as the excitation source.The stress distribution of the pipeline is simulated and compared with the experimental results,the results of simulation and experiment are the same,and the stress concentration is more serious at the first bend of the exhaust pipe and the stress is relatively small in other parts of the pipeline.In order to solve the problem of excessive bending stress,a parameter optimization design method is applied to enhance the stress resistance.
