LMS　Test.Xpress融合了LMS公司在声振工程领域超过25年的经验，是可扩展测试和设计解决方案整套产品的一部分，提供最佳的可扩展性、开放性和投资保护。您想从现有的4通道分析仪开始，将您的系统扩展为先进的、多通道的工程解决方案吗？有了LMS Test.Xpress，使之成为可能。

LMS Test.Xpress提供了完整且简单易用的解决方案，用于全身振动和手-臂振动ISO标准验证试验。系统能够根据ISO流程进行测量，并且在测量的同时提供实时反馈，以及是否符合ISO标准的反馈。结合便携式LMS SCADAS III硬件，LMS Test.Xpress解决方案还适用于各种试验室或者现场试验。此外，当不能满足前面所表述的标准时，LMS Test.Xpress还提供了多种功能诊断振动问题。为了支持这项功能，LMS Test.Xpress具有实时的FFT分析，阶次分析，倍频程分析和输出功能，并且能够同时进行上述多项功能。除此之外，LMS Test.Xpress还提供了操作简单的高级分析功能，例如滤波、信号平滑、平均值，以及各个通道信号之间的数学运算。

LMS Test.Xpress人体振动解决方案能够根据ISO要求的位置（立位、坐位或者卧位）和/或配置（单个或者两个手柄），测量时域信号。为了与ISO标准一致，测量的时域信号，与相应的ISO时域滤波器加权，然后计算矢量和以及相应的加权RMS。加权RMS值与ISO标准规定的极限值进行多次比较，来验证是否符合标准。此外，可以实时计算并显示振动剂量值（Vibration Dose Values，VDV），利用彩色图清晰地显示是否超出暴露极限（暴露极限通常作为人体可以承受振动量的上限）和/或ISO标准规定的特定限值。

整个流程可以利用Microsoft Excel或者Word生成详细的报告。如果没有满足ISO标准，那么原始的时域数据和所有在线数据将存储在一个单独的项目文件中。这样，原始数据可以在LMS Test.Xpress软件中用于进一步分析，查找过度振动问题的根源，并且提出解决方案。因此，避免了不必要的重复试验。

为了确保符合ISO测量流程，减少操作者失误，整个试验程序从开始测量到最后的报告生成，可以完全自动运行，并且通过设定用户密码进行保护。自动化功能可以定义特殊的测量设定，所需的数据显示形式，用于数据分析的适当的数字功能，以及公司统一的报告格式。预先定义的测量-分析-报告流程仅需要三次点击用户界面即可完成。

LMS Test.Xpress软件是与小巧的便携式LMS SCADAS III数采前端集成在一起的。测量通道数可以从4通道扩展至40通道，在一次试验中能够测量各个方向三轴向传感器信号——甚至可以测量多个座椅不同位置上的信号。此外，还可以将全身振动标准ISO2631和手-臂振动标准ISO5349结合在一起进行测量。还可以通过增加通道数来测量速度、温度、噪声或者其他数据。这样，获得的有用信息可以用来分析并且诊断过度振动问题的根源。

LMS Test.Xpress ——Integrated platform for noise, vibration and durability
LMS Test.Xpress ——Integrated platform for noise, vibration and durability
Traditional analyzers are extremely flexible tools to qualify products’ noise, vibration or durability performances. They are easy to operate and immediately show the frequency content of a vibration, sound or fatigue signal. They are, however, also very limited. Why restrict measurements to just 2 or 4 channels, when productivity could be so much higher with 8 channels or more? What about direct …
