Abstract

The invention relates to a CAE-based simulation optimization method of a motor for a power automobile. The method comprises the following steps: providing a virtual motor; carrying out static electromagnetic field analysis on the virtual motor, and calculating static electromagnetic parameters of the virtual motor according to a static electromagnetic field calculation model; performing transientelectromagnetic field analysis on the virtual motor, and calculating transient electromagnetic parameters of the virtual motor according to a transient electromagnetic field calculation model; judgingwhether the static electromagnetic parameters and the transient electromagnetic parameters of the virtual motor are in an electromagnetic parameter threshold range or not; if yes, vibration noise analysis is conducted on the virtual motor, vibration noise is calculated according to a vibration noise calculation model, whether the vibration noise is within the vibration noise threshold range or not is judged, and if yes, motor initial parameters are stored to serve as motor design parameters to design the motor. The method disclosed by the invention not only meets the conditions of common motors, but also meets the condition of low vibration noise, and adopts the modes of parameter linkage, scanning characteristics and the like, thereby greatly shortening the development period and savingmanpower and material resources.

Description

technical field [0001] The invention relates to the field of motor optimization design, in particular to a CAE-based simulation optimization method for motors used in power vehicles. Background technique [0002] At present, motors are widely used as an energy conversion tool in transportation, industry, aviation and other places, and have become an indispensable part of national modernization. With the increasingly stringent energy policy, the development of high-performance, low-cost motors has become an urgent need , The traditional motor design scheme often adopts the method of scaling up the size and calculating based on the equivalent magnetic circuit, which brings problems such as long calculation time, inaccurate calculation, and the inability to fully optimize the performance of the motor. [0003] The motor for power vehicles refers to the vehicle-mounted power supply as the power, the motor for power vehicles uses the motor to drive the wheels, and the motor for p...
