摘　　要：针对铁路货车在高速重载行车状态下的轮轴智能检测和轴承故障难以诊断问题,研究设计了一种高速重载铁路货车轮轴智能检测系统。通过构建系统的软件和硬件结构模型,制定通信指令集的编码和解码规则,设计智能化指令调度策略,编写专家控制产生式规则。同时采用基于有限脉冲响应-经验模态分解(FIR-EMD)和改进支持向量机(SVM)的铁路轴承故障诊断方法,实现铁路轴承故障有效分类。提出一种高速重载轮轴检测领域中可编程的智能化测控方法,能够对现场设备的控制程序进行重构和功能扩展。实验测试及结果表明,该系统设备的设计满足铁路货车轮轴高速度、大重载、智能化检测的需求。Aiming at the problem of intelligent detection about axle and bearing fault diagnosis of railway wagons under high-speed and heavy-duty driving condition,this paper designs an intelligent detection system for wheel and axle of railway heavy trucks with high speed.The effective classification of railway bearing faults is realized by constructing the software and hardware structure model of the system,formulating coding and decoding rules of communication instruction set,designing intelligent scheduling strategy of instruction,writing expert control generation rules and using the fault diagnosis method of railway bearing based on finite impulse response-empirical mode decomposition(FIR-EMD)and improved support vector machine(SVM).This paper presents a programmable intelligent measurement and control method in the field of detection on axle with high speed and heavy load,which can reconstruct the controlled program of field equipment and implement functional extensions.The experimental results show that the design of the system realizes intelligent detection of truck axles with high speed and heavy load.
