KiDAQ数据采集系统具备无限测量的潜能


Kistler's KiDAQ modular integrated data acquisition system lets users explore new ground in the design of complex measuring chains commonly found in research and development. An initial look at the system and how it can be used in cutting force measurement was taken by the machine tool laboratory of RWTH Aachen University.

The Laboratory for Machine Tools and Production Engineering of RWTH Aachen is one of the Germany's leading research institutes in the machine tool sector. Four chairs are devoted to research in the fields of production systems and factory planning, the technology of manufacturing processes, process monitoring and quality management. Not only does the institute conduct basic research, it also cooperates with leading companies across the globe to foster innovation and blaze a trail into new technological worlds. Kistler's partnership with the laboratory dates back almost 50 years and stems from the high performance of the company's piezoelectric measurement technology.

Given their high-precision, very wide measurement range (from a few newtons to a meganewton) –and high resilience even in demanding ambient conditions, piezoelectric (PE) sensors are predestined for implementation scenarios with high requirements. They are ideal for use in highly dynamic force measurements, such as on machine tools that mill grooves into turbine blades, The laboratory also uses PE dynamometers for combined force and torque measurements when conducting complex modal analyses.

Data acquisition system (DAQ) measures more than 20 different analog and digital signal types

通过模块化和整体化的KiDAQ数据采集系统,奇石乐为用户构建了在研究与开发中会遇到的复杂测量链,并开辟了更大的自由空间。最初,在莱茵-威斯特法伦亚琛工业大学(RWTH)的机床实验室(WZL),工程师看到了在切削力测量领域使用、配置的该类系统。

亚琛工业大学(RWTH)的机床实验室(WZL)是德国机床领域领先的研究机构之一。研究领域划分为四大板块,包含生产系统和工厂计划、加工工艺技术、过程监控以及质量管理。同时,该研究所不仅致力于基础研究,还与全球领先的公司积极合作,践行创新并推动新技术领域的发展。机床实验室(WZL)与奇石乐的合作已经有近50年的悠久历史,研究方向是压电测量技术的性能。

由于这些传感器具有十分宽广的高精度测量范围(从几牛顿到兆牛顿)以及在苛刻的环境条件下也具有很高的耐用性,所以奇石乐压电(PE)传感器天生适合于极高要求的应用场合。因此,它们特别适合于高动态力的测量 – 例如在拉床上铣削涡轮叶片上的凹槽。在机床实验室(WZL)也经常将压电(PE)测力计用于力/力矩组合测量,得到复杂的模态分析数据。

一应俱全 – 从传感器到云端

新型数据采集系统KiDAQ是专门为此类应用而设计。得益于模块化和整体化的方案,能够轻松配置包含不同传感器(力、压力、加速度、扭矩等等)的复杂分布式测量链并将其投入使用。由软件和硬件组件构成的奇石乐生态系统采用开放式设计,可以集成第三方制造商的传感器和设备。此外,依据于可用的云链接,不仅可以与商业合作伙伴进行合作,也使物联网(IoT)的应用成为了现实。

Sascha Kamps是机床实验室(WZL)产品技术群负责过程监控开发的工程师,他有幸测试了新型数据采集系统KiDAQ,并评论到:“奇石乐作为压电传感器技术的领先者,经过大量的努力,现在将提供自己的数据采集系统,给用户配置测量链的所有部分,这真是令人振奋的消息。凭借模块化和通用化的方案以及新功能,我认为该系统极具吸引力,并可作为实验室现有采集系统的改进方案,不仅适用于切削力测量领域,还可在诸多其他研究领域大放异彩。”
