Abstract

In recent years, domestic commercial vehicles have developed rapidly, and many series of products have been developed from light, medium to heavy. However, the vibration and noise problems of the cab of commercial vehicles during driving still fall far short of the requirements expected by customers. In order to improve the comfort of commercial vehicle cab during driving, the mounting system and vibration isolation and noise reduction system of commercial vehicle cab are designed. The cab mounting structure is an active electromagnetic mounting structure. Through the blind source separation algorithm built in the cab mounting ECU, the impact of vibration on the cab during driving can be quickly eliminated. The vibration isolation and noise reduction system adopts double-layer sound insulating glass and ANC active noise reduction system to minimize the noise transmitted to the cab. Through the self-designed active electromagnetic mounting structure and the vibration isolation and noise reduction system composed of double-layer sound insulating glass and ANC active noise reduction system, the comfort of commercial vehicles during driving is improved, which meets the expectations of customers.
