Generally, it is said that drive motors used in electric cars have less vibration than engines, however, vibration caused by torque ripple may be transmitted to the entire vehicle becoming an issue. Conventionally, vehicle drive simulation using an ideal motor as input has been used to evaluate vibration during electric vehicle driving, but in order to properly evaluate vibration while driving, detailed motor characteristics such as torque spatial harmonics must be taken into account.
The solution for this is a JMAG/Adams/Simulink coupled simulation. Adams is a universal mechanism analysis software developed by MSC Software Corporation and supports a wide range of multibody dynamics analysis. By linking these software applications, it is possible to easily and accurately evaluate vibration during vehicle drive.
