Vibroacoustic prediction and mechanism analysis of claw pole alternators

Abstract:

A multiphysics simulation model that consists of electromagnetic field, mechanical field, and acoustic field was established to predict the electromagnetic vibration and noise of claw pole alternators. First, magnetic force exerted on the stator inner surface was calculated by three-dimensional (3-D) transient electromagnetic field analysis and the characteristic of magnetic force was analyzed. Second, finite-element modal analysis of alternator assembly was conducted while taking into account the anisotropy of the stator core and armature winding and the installation condition. Simulation result was validated by modal test. Afterward, magnetic force was transferred to the structural mesh using mesh mapping method and the vibration and noise were predicted by using mode superposition method and boundary-element method, respectively. Simulation results agree well with those measured by experiments. Finally, the mechanism of electromagnetic vibration and noise of the claw pole alternator was revealed with the help of 2-D Fourier transform of magnetic force and the mode participation factor of each mode. Results show that for three-phase 12-pole/36-slot claw pole alternator, electromagnetic vibration, and noise are mainly caused by the zeroth-order (circumferential spatial order) force harmonics whose frequencies are 36kfr (k = 1, 2, 3,...) and the sixth-order (circumferential spatial order) force harmonics whose frequencies are (36k ± 6)fr (k = 1, 2, 3,...).链接地址：http://ieeexplore.ieee.org/document/7801118/

Robust control for four-wheel-independent-steering electric vehicle with steer-by-wire system

Abstract:

A four-wheel-independent-steering (4WIS) electric vehicle (EV) with steer-by-wire (SBW) system is proposed in this paper. The fast terminal sliding mode controller (FTSMC) is designed for the SBW system to suppress external disturbances. Taking unstructured and structured uncertainties into consideration, a robust controller is designed for the 4WIS EV utilizing μ synthesis approach and the controller order reduction is implemented based on Hankel-Norm approximation. Since sideslip angle is the feedback signal of robust controller and it is hard to measure, the extended Kalman filter (EKF) is employed to estimate sideslip angle. To evaluate the vehicle performance with the designed control system, step and sinusoidal steering maneuvers are simulated and analyzed. Simulation results show that the designed control system have good tracking ability, strong robust stability and good robust performance to improve vehicle stability and handing performance.

我个人而言，选择读博并不是因为有很高的学术追求，或者说是为了在人类的知识边缘有所突破，我的初心就是想做好技术，这也许因为我的专业车辆工程太工程化了。冲动的决定需要毅力与恒心去完成，读博就是这样一件事，数不清个日日夜夜，看的文献越多越觉得自己无知，也越迷茫，找不到方向，导师的引导纠正了自己的研究方向，卯足劲儿在这一点上挖，越挖越深，慢慢我投入进来了，在自己感兴趣的领域越做越顺利，也发现了自己研究的价值，很多过来人都说过读博的过程就是痛苦并快乐着的过程，这是真的，只有真正经历的人才能体会到。最后，以我导师经常给我说的话作为寄语，做研究，再小的一个点，只要你不断去挖掘，总能做出点成绩。

电子液压制动系统液压力控制发展现状综述

摘要：

回顾电子液压制动系统液压力控制问题。电子液压制动系统（Electro-hydraulic Brake System, EHB）是汽车制动系统的一个重要发展方向。主要特征是采用电子元器件替代传统制动系统中的部分机械零部件，保留了原有成熟可靠的液压部分，具有结构紧凑、响应快速、易于实现再生制动、制动力可精确控制等突出优点，容易实现多种主动安全控制功能。在剖析电子液压制动系统组成架构的基础上归纳出电子液压制动系统的液压力控制架构，以控制变量和控制算法为突破口，从主缸液压力控制和轮缸液压力控制这两个层面分别对国内外的研究进展进行综述，对能够应用于电子液压制动系统上的电磁阀特性进行分析，对其控制方式进行研究，提出对于电子液压制动系统液压力控制的发展展望。汽车的电动化和智能化对液压力控制算法的控制精度、适应性和鲁棒性要求进一步提高。液压力控制算法对整车的制动舒适性和操纵稳定性影响也有待进一步讨论。

High frequency vibration characteristics of electric wheel system under in-wheel motor torque ripple

Abstract:

With the introduction of in-wheel motor, the electric wheel system encounters new vibration problems brought by motor torque ripple excitation. In order to analyze new vibration characteristics of electric wheel system, torque ripple of in-wheel motor based on motor module and vector control system is primarily analyzed, and frequency/order features of the torque ripple are discussed. Then quarter vehicle-electric wheel system (QV-EWS) dynamics model based on the rigid ring tire assumption is established and the main parameters of the model are identified according to tire free modal test. Modal characteristics of the model are further analyzed. The analysis indicates that torque excitation of in-wheel motor is prone to arouse horizontal vibration, in which in-phase rotational, anti-phase rotational and horizontal translational modes of electric wheel system mainly participate. Based on the model, vibration responses of the QV-EWS under torque ripple are simulated. The results show that unlike vertical low frequency (lower than 20 Hz) vibration excited by road roughness, broadband torque ripple will arouse horizontal high frequency (50–100 Hz) vibration of electric wheel system due to participation of the three aforementioned modes. To verify the theoretical analysis, the bench experiment of electric wheel system is conducted and vibration responses are acquired. The experiment demonstrates the high frequency vibration phenomenon of electric wheel system and the measured order features as well as main resonant frequencies agree with simulation results. Through theoretical modeling, analysis and experiments this paper reveals and explains the high frequency vibration characteristics of electric wheel system, providing references for the dynamic analysis, optimal design of QV-EWS.
