摘要:

针对电子油门踏板输出信号非线性的问题,建立了电子油门踏板动态响应的数学模型和结构力学模型,并进行了仿真。分析了复位弹簧刚度和机构阻尼比对踏板动态响应的影响,并在电子油门踏板综合性能测试台上进行了动态响应的测试,获取了动态响应的量化数据。数据的结果显示所建立的模型基本正确,揭示了不同复位弹簧的刚度和机构阻尼比对其动态响应的非线性性的影响。

Abstract:

To electronic accelerator pedal output signal of the nonlinear problem, established the mathematical model and the structural mechanics model of the dynamic responses of the electronic accelerator pedal, and simulated, analyzed damping institutions and the return spring’s stiffness effect on dynamic responses of the pedal, and the electronic accelerator pedal comprehensive performance test bench has carried on the dynamic response tests, to obtain quantitative data of the dynamic response. Data is basically a correct results show that the established model, reveals the different return spring of electronic throttle pedal and damping of institution effects on the nonlinear resistance of dynamic response.
