In order to ease the stress and improve the service quality, Zizhu Digital Hub co., Ltd. proposed to construct a second staff canteen and brought forward its preliminary scheme.

Based on the wheel hub unite, analysis its structure, stress field distribution of wheel hub were acquired, which can provide the important design guide for wheel design engineers.

Improvement of the processing precision can help to improve the contact state between wheel seat and wheel hub bore, reduce the maximum residual pull stress in wheel seat due to press mounting.
