摘要:In order to decrease the minimum of door closing effort for a SUV, influence factors are comprehensively analyzed, which involve door cabin-pressure, seal stiffness, compression load, door weight, door latch force, door hinge and door opening limiter friction effect, etc. Applying influence factor separation method, door closing energy is tested to analysis the main influencing factors. Then,according to the main factors, rod contour line of the door opening limiter and slider spring stiffness are designed and optimized by CAE, improve programme is proposed and carried out. Test results show that door opening limiter is the main influence factor on door closing energy and velocity, and the improve programme has good effect for decreasing the minimum of door closing effort. It shows that the minimum of door closing energy decreases from 6.96 J to 2.83 J and the minimum of door closing velocity decreases from 1.05 m/s to 0.7 m/s, which indicate the significant improvement for door closing comfort.
