Measurement systems, test benches and data analysis solutions, no matter how complex their design, have only one purpose: to obtain and document information about the device under test, with regard to its functionality and quality. All the effort spent on testing technical systems always leads to a test result which – regardless of how it […]
For a long time, it was everywhere, but recently there wasn’t much to hear about – NI’s big analogue data (TM), characterised by the five Vs: volume, variety, velocity, value and visibility. Of course, it is still there and growing. Perhaps it has fallen out of the spotlight because we have become accustomed to it. […]
The use case is typical: many sources provide data that is evaluated in a standardized way and then used by a group of users. In this specific case, measurements on vehicles in drive simulations produce large amounts of data around the clock. This data is processed, searched for events and used to calculate characteristic parameters. […]
Process data objects (PDOs) are typically used in EtherCAT (and other fieldbuses) to transport (cyclical) real-time data, while service data objects (SDOs) are used for (acyclical) parameterization. But what if the PDOs are not available for cyclical control due to customer requirements, but the reaction of the test object to cyclical setpoints is to be […]
This week’s NI workshop in Munich focuses on DIAdem software. NI describes DIAdem as a tool “to quickly find, test, analyze and document measurement data.” It is often forgotten that DIAdem is also a practical tool for performing a wide range of measurement and control tasks. Numerous drivers and interfaces are available for this purpose. […]
At müller+krahmer, we spend a lot of time and effort convincing our customers that Excel – despite all its functionality – is not the tool of choice for analyzing technical data, especially when it comes to large amounts of data. But there are exceptions to the rule. We have just made the latest one with […]
Testing the durability of seat foams for motor vehicles means measuring the hardness several times, conditioning the foam, carrying out a cyclic fatigue load (the so-called fatigue test) with precisely defined parameters, recording the results of all steps and finally evaluating them. This usually requires several expensive and highly specialized devices, various software and a […]
