摘　　要：参考UIC513《铁路车辆内旅客振动舒适度评价标准》,并结合传感技术和信号处理技术,在Lab-VIEW7.0环境下开发了一套列车振动舒适度检测和评价系统。该系统以计算机为硬件工作平台,以图形化编程语言LabVIEW7.0为软件开发平台,主要由传感器及信号调理、数据采集、数据处理、舒适度级评定4大模块构成,具有数据采集、数据保存及数据分析等功能,界面友好,易于操作。This article introduces a suit of system of train vibration comfort test and evaluation in LabVIEW7.0, referring to the standard--UICS13, combined with sensor technology and signal analysis technology. The system takes computer as the hardware platform, and takes LabVIEWT.0 as the softwa platform. It is mainly composed of sensors with correlative circuit, data acquisition, signal analysis （time domain analysis, frequency domain analysis） and comfort evaluation, with the function of data acquisition, data storage, data analysis, friendly interface and easily operated.
