摘要
文章使用python/VBS脚本语言开发了一套完整的汽车NVH仿真后处理流程自动化系统,弥补了商业软件的不足。此系统集成Meta和Office软件,实现了动刚度、NTF和VTF分析的自动后处理和自动生成报告。此系统的应用将以往一到两天的工作量缩减到十几分钟,显著缩短了分析周期。自动化系统功能还包括:提供多方案对比功能,方便NVH分析工程师进行方案评优;仿真结果自动写入性能管控数据库,有利于企业知识的积累;通过统计图表分析响应点的噪声分布,快速识别风险点。
An automatic post-process system for NVH simulation is developed by using the python/VBS programming language.The tool integrates Meta and Office software and it makes up the weakness of commercial software.The tool makes the batch post for dynamic stiffness and transform function analysis realized.The application of the tool reduces the workload from one or two days to less than twenty minutes,remarkably shortens the simulation cycle.The automation tool also includes functions as follows:provides multi result comparison function,which is convenient for NVH engineers to evaluate the scheme quickly;automatically writes the simulation results into the performance control database,which is conducive to the accumulation of knowledge;analyzes the noise distribution of response points through statistical charts,which can helps engineers to identify risk quickly.
