机车车辆动力学试验数据分析处理软件DASO

DASO软件的主要功能是软件设计中提出了段标和长短链断点的概念,解决了线况混叠的难题。提出虚拟通道的概念,方便了信号之间的相关分析。借鉴摆式列车的思路,设计了陀螺仪的处理方法,解决了线况识别的困难。设计了专用的数据库,加快了数据统计和查询的速度。增加了测力轮对选桥的算法、相对摩擦系数的算法和舒适度指标的算法,拓展了软件的分析处理能力。

Development of Test Data Analysis Software DASO of Locomotive and Car Dynamics Performance

The main functions of the DASO software include the concept of segment marking with long and short chain break-points and thus solves the problem of the confused and overlapped track conditions. It presents the concept of the dummy channels for the convenience of signal related analysis. Benefited from the tilting train concept, the method of gyroscope processing is designed, thus overcoming the difficulty of track condition identification. The specialized database is designed and the data statistics work and data retrieving work are sped up. Thus we have got more ways of calculation for the bridge selection of the instrumented wheelset, the relative function for relative friction coefficient and the riding comfort index. The analysis and processing capability of the software is thus extended.
