摘要
针对纯电动公交车运行距离短等特点,设计了纯电动公交车的AMT控制系统,AMT控制系统能够降低驾驶员的疲劳度,提高纯电动公交车的运行性能安全性。通过Matlab Simulink仿真模块建立纯电动公交车的整车AMT控制系统模型,最后通过CAN总线对各个模块进行通讯,实现整车的在线监控的目的。实践证明,设计的AMT控制系统的可行性。
This paper presents a vibration signal feature extraction method of rolling bearing based on normal distribution model parameters.Firstly,the vibration signals of rolling bearing collected in the four operating states are established normal distribution model,and then the shape and position parameters of the model are estimated by maximum likelihood method.Finally,the estimated shape parameters and position parameters are used to characterize the running state of the rolling bearing.The characteristic information is input to the LS-SVM classifier for pattern recognition and fault diagnosis.
