| description | The invention relates to the technical field of motor noise, in particular to the technical field of aerodynamic noise of a motor fan, and specifically relates to a simulation evaluation method for aerodynamic noise of a self-ventilation motor fan. The invention aims to provide a motor fan aerodynamic noise simulation evaluation method which is short in calculation period and high in applicability, and comprises the following steps: firstly, acquiring input information such as an original geometric model, a rotating speed and a boundary of a motor, then carrying out steady-state flow field analysis and data extraction, and taking an extracted result as an agent model input parameter; calculating the aerodynamic noise sound power level of the centrifugal fan of the motor; and after the sound power level pre-estimated value is obtained, performing standard-exceeding risk level evaluation on the sound power level pre-estimated value and a standard limit value or customer requirements, and after the evaluation is |
