摘要
针对汽车平顺性试验数据处理系统的关键问题进行了研究。通过比较几种功率谱算法的特点,确定采用Welch法来计算功率谱密度;通过比较几种数据处理平台的优缺点,确定采用数值分析软件Matlab的GUI模块来搭建汽车平顺性试验数据处理系统。所开发的系统操作简单,界面友好,点击按钮即可完成数据曲线的绘制及生成试验报告,可提高工作效率,节省软件开发费用。
In this paper, the key issues of automobile ride comfort test data processing system are investigated. By comparing the characteristics of several power spectrum algorithms, we decide to use the Welch method to calculate the power spectrum density; by comparing the advantages and disadvantages of several data processing system platforms, we decide to use the Matlab GUI module to build the automobile ride comfort test data processing system. The system has the advantages of simple operation and friendly interface. Data curve drawing and test report generation can be realized by simply clicking the button which greatly improves working efficiency and saves the cost of software system development.
