Analysis of the Effect of Three-Dimensional Topology Modification on Temperature Field and Thermal Deformation of Internal Helical Gears Pair

Applied Sciences
The transmission accuracy and meshing performance of the gearbox is determined by the internal helical gears pair. Thermal deformation of internal helical gears pair is derived from sliding friction between the contacting teeth surface, resulting in ...

Multibody Simulation of Helical Gear Noise and Vibration Behavior Using MSC ADAMS

Engineering Proceedings
The premium electric-vehicle market demands exceptionally quiet transmissions because the absence of engine masking makes gearbox noise more perceptible. Virtual NVH (noise, vibration, and harshness) evaluation requires coupling elastic deformation, gear–

System-Level Harmonic NVH Engineering in Electric Drivetrains: A State-of-the-Art Review from Gear Microgeometry to Sound Branding

World Electric Vehicle Journal
Electric vehicles (EVs) have fundamentally changed the noise, vibration, and harshness (NVH) landscape of automotive powertrains. In the absence of masking internal-combustion-engine noise, harmonic components such as gear whine, electric-motor orders ...
