作为有高适应性和可扩展性的通过噪声试验解决方案,LMS Test.Lab通过噪声解决方案可适应试验精度要求,并可根据需要进行扩展。LMS通过噪声试验基于可靠的硬件和软件,包含了最新的LMS SCADAS数据采集前端和无线传输功能,易于使用,试验快速、准确,结果符合国际和本地标准。

取决于不同的试验方法,该系统适用于一个或两个操作者。无论何种方法,都以直观的界面在整个试验过程中清楚地指导使用者:从试验准备到报告。在试验开始后,所有的数据马上可以在场边察看,现场即可判定车或零部件是否符合标准。

LMS Test.Lab通过噪声解决方案支持许多标准,包括:ISO 362和ISO 362(2007版)、SAE J366、 SAE J986、 SAE J1470、 F76A US 和Trias20。支持排气管噪声(EEC 93/97、ISO 5130、Trias 20)和轮胎噪声(Trias20)等相关零部件深度试验的标准。当出现新的标准时,可以很容易集成进去。

LMS Test.Lab通过噪声试验系统可按照自定义流程和特定要求进行配置。作为常见的应用,LMS提供了三种典型配置方案: 

  • Track-based通过噪声试验,LMS SCADAS采集系统安置在试验场一侧。该方法只需在车内安装很少的设备。
  • In-Vehicle通过噪声试验,LMS SCADAS采集系统安置在车辆内部,用来获得更多的试验通道,以进行更深入的分析
  • 对高级的工程分析试验, 试验场一侧以及车辆内部都应采集大量的数据。对于这种任务,两个系统可以采用内置的LMS SCADAS GPS接收器,进行组合、同步。



特点

  • 从设置到报告,完整的标准支持,包括修订版362:2007和SAEJ 1470
  • 基于车辆在场内的行进位置,进行在线倍频程和声压级监测,试验状态指示
  • 司机辅助:在车内有监测速度、转速、位置和气候条件的图形界面
  • 单人操作
  • 完全认证系统(硬件:ISO 61672规范;车辆位置感知:ISO 362的要求)
  • 可以保存额外的通道和时域数据,以作进一步工程分析。

优点 

  • 用于室外通过噪声法规和工程分析的完整的采集和报告工具包
  • 通过运用高端的后处理平台,结合验证和工程试验,优化试验与分析的时间
  • 按照规定的标准,有效可靠的噪声评估
  • 开放性平台,易于实施新标准
  • 试验进程与质量的在线反馈
  • 高可靠性,减少错误,提高效率
  • “一键操作”快速生成标准报告



    Covering a range of industries, LMS application cases let you discover how LMS solutions help our customers solve their real-life engineering challenges. 

    UTAC accelerates noise and vibration testing with LMS Test.Lab  

    industrial_analysis_laboratory_UTAC2.jpgUTAC, a leading company in testing and certification services, deployed LMS Test.Lab in its environmental laboratory for acoustic testing, citing its testing speed, engineering capabilities, precision, and ease of use as key differentiators. UTAC estimates that testing campaigns run with LMS Test.Lab deliver a 30% time gain compared to tests with other tools. Thanks to LMS Test.Lab, UTAC can offer its customers a precise diagnosis of acoustic problems.



    Volvo Truck masters exterior noise performance

    trucks driveline subsystem exterior noise performance engine intake exhaust gearbox 3Since ever-more demanding noise regulations are imposed on truck manufacturers, Volvo Truck leaves no stone unturned to minimize the exterior noise of the company’s extensive truck range. At the NVH laboratories of Volvo Truck, engineers systematically measure, analyze and optimize exterior truck noise under different vehicle operating conditions using LMS NVH testing systems. During the development of new truck models, Volvo Truck NVH specialists focus on reducing the noise generated by the entire truck driveline, including engine, intake and exhaust, gearbox and transmission.


    General Motors selects LMS for exterior pass-by noise testing

    exterior pass by noise testingLMS delivered a fully integrated testing and analysis system to perform pass-by noise certification of newly developed GM vehicles. GM selected LMS for its strong support of the upcoming revision of the ISO 362 standard. GM also valued the LMS system for its efficient execution of exterior noise tests and related troubleshooting analyses. The strong integration of the new system in the extensive installation of LMS systems for noise and vibration engineering at GM will enable its engineers to easily reuse and leverage exterior noise test data throughout the vehicle development process.


    Characterization of Wheel Noise During Train Pass-By at Fiat Ferroviaria

    wheel noise pass by 1Reducing the pass-by noise of trains is an important issue and innovative companies, such as Lucchini of Italy, are developing a range of new low noise wheels to address the problem. But how can the contribution of a new set of wheels to the overall pass-by noise levels be assessed - given the multiple sources contributing to overall noise levels, the couple of seconds it takes for a train to flash by at 220kph, and the Doppler shifts distorting?
