【摘要】：电动助力转向系统是一种直接依靠电机提供力矩,来辅助汽车转向的新型汽车转向助力系统。虽然机械助力转向系统和液压助力转向系统发展时间久远、技术已经成熟,但不能满足对汽车节能性和环保性的需求,也与现代微电子技术的发展不适应。电动助力转向系统具有能显著提高驾驶员操作方向盘的舒适性和汽车行驶的安全性、减少对环境污染等优点,符合现代汽车发展的需求,逐渐成为转向系统的主流。电动助力转向控制器是电动助力转向系统的重要组成部分,其性能决定了汽车行驶过程的操纵性、稳定性和安全性,因此随着电动转向系统的发展,电动转向控制器的质量越来越受到人们重视。为检测电动助力转向控制器的质量,需使用电动助力性能测试试验台。使用传统性能检测试验台,检验工作量大、费时费力、成本高昂。本文研究的电动助力转向控制器性能测试试验台,是在以转向控制器的基本性能检测试验台的基础上,以简化结构、降低成本、方便测试、平台开放、降低试验安全隐患为原则,结合虚拟测试技术,利用Labview虚拟软件开发平台所构建。针对转向轴助力式电动助力转向控制器的基本性能和待检参数,结合生产实际和实际测试需求,对电动助力转向控制器性能检测试验台的原理和设计要求进行分析讨论,确定试验台要完成的功能,确定试验台的组成和台架设计。采用PLC的输出控制伺服电机转动来实现模拟驾驶员转动方向盘系统；通过磁粉制动器控制器来控制磁粉制动器模拟路面阻力系统；通过使用采集卡对数据进行采集和处理,完成数据采集系统；并且对试验台其他设备进行选择和配置。利用Labview虚拟软件开发平台,使用新型模块编程技术,针对各个模块的功能进行设计,考虑数据采集中的环境干扰问题,对检测系统的前面板和后面板进行了总体规划,根据使用需求设计友好的人机界面。确定电动助力转向控制器性能测试试验台测试流程,在试验台上对转向轴式电动助力转向器的控制器进行测试,通过与标准试验台的测试结果对比,验证试验台的可行性及产品的合格性。
[Abstract]:Electric power steering system is a new type of automotive steering support system, which directly relies on the motor to provide torque to assist the steering of the automobile. Although the mechanical power steering system and the hydraulic power steering system have developed a long time, the technology has been mature, but it can not meet the requirements of energy saving and environmental protection for the automobile, and it is also with the modern microelectronic technology. The electric power steering system can significantly improve the comfort of the steering wheel and the safety of the car, reduce the environmental pollution and so on. It is in line with the demand of modern automobile development, and gradually becomes the mainstream of the steering system. The electric power steering controller is an important part of the electric power steering system. The performance determines the maneuverability, stability and safety of the driving process, so with the development of the electric steering system, the quality of the electric steering controller is getting more and more attention. In order to detect the quality of the electric power steering controller, the electric power performance test rig needs to be used. In this paper, the performance test test rig of the electric power steering controller, based on the basic performance testing test bench, is based on the principle of simplifying the structure, reducing the cost, the convenience of testing, the opening of the platform, reducing the hidden danger of the test, and using the virtual test technology and using the Labview Based on the virtual software development platform, based on the basic performance and parameters of the steering axis power steering controller, the principle and design requirements of the performance test bench for the electric power steering controller are analyzed and discussed in combination with the actual production and actual test requirements. The function of the test bench is determined and the test bench is determined. It uses PLC output to control the rotation of the servo motor to simulate the driver's steering wheel system. The magnetic powder brake controller is used to control the simulation of the resistance system of the magnetic powder brake. The data collection and processing are done by using the acquisition card, and the data acquisition system is finished. The equipment is selected and configured. Using the Labview virtual software development platform and using the new module programming technology, the function of each module is designed and the environmental interference in the data acquisition is considered. The overall planning of the front panel and the rear panel of the detection system is carried out, and the friendly human-computer interface is designed according to the use requirement. The power steering controller performance test test rig is tested on the test bench, and the test results are compared with the test results of the standard test rig to verify the feasibility of the test rig and the quality of the product.
