| 摘 要： | 车用氧传感器作为电控系统一个闭环控制(对空燃比)反馈信号发生器,它将汽车尾气中氧气的浓度信号送到ECU(电子控制单元),保持空燃比在某一个恒定值(λ=14.7),文章对一种车用氧传感器密封元件的受力及变形情况进行了理论分析,并用大型通用有限元分析软件ANSYS来实现,得到了比较满意的结果。

| Abstract: | Oxygen sensor used in vehicle as a closed loop control(hollow ignite ratio)feedback signal generator of electric control system,it will transmit oxygen concentration signal of exhaust gas of vehicle to ECU(electric control unit), keep hollow ignite ratio at a invariable value(λ=14.7)。The article gives accept force and distortion analysis of a airproof component of oxygen sensor used in vehicle a theoretic analysis,and use software ANSYS realize it,and receive comparatively fine result。 |
