燃油汽车软起动降噪技术研究

摘要

In the process of gas car started, the friction between the flywheel and the drive gear will generate harsh howling sound. In order to reduce the noise, this paper proposes a soft starting system of fuel vehicles and designs the corresponding soft start circuit. In this paper, three soft start circuits are simulated. By comparison, the optimal soft starting scheme is determined.%为了降低燃油汽车在启动时，飞轮与驱动齿轮相互摩擦所发出的刺耳的啸鸣声，提出了一种燃油汽车的软起动系统，并完成了相应的软起动电路设计。本文通过对3种不同的软起动电路进行仿真对比，确定了最优的软起动方案。
