When evaluating the Czinger 21C's handling stability and the durability of its components with a imc data acquisition solution, Divergent 3D's test engineers focused on technically verifiable measured data. Studying the forces and moments acting on the wheels enabled the verification and optimization of processes and allowed conclusions about the material used, tire profiles, and the safety of the various assistance systems.
Torsional vibrations of wheelsets are a challenge in rail transport. The torsional vibration of a wheelset - also known as rolling - reduces traction and leads to increased wear. Together with the experts of the DNV-GL Maritime Advisory, imc has developed a rolling protection system (Torsional Vibration Limiting System, abbr. TVLS). It is characterised by its flexibility, performance and availability.

A rail vehicle is subject to various dynamic loads under real operating conditions. Determining these loads is a cornerstone of railroad vehicle development. The aim of the project at
Gutehoffnungshütte Radsatz GmbH (GHH-Radsatz) is to develop models that simulate the dy-namic load of tram wheels. To this end GHH-Radsatz developed a measurement wheel for use while the tram is operating in order to acquire data on relevant parameters. This included using a telemetry system from the imc partner KMT – Kraus Messtechnik GmbH.
The SBB has developed stationary wheel-load checkpoints that can automatically acquire key data from a passing train in real time. With the help from imc, these checkpoints are equipped with high-precision strain gauge bridge amplifiers, as well as an industrial PC according to customer specifications.
The system is designed to acquire safety-relevant load data, such as axle overloading and cargo shifting. It also recognizes flat spots on the wheels.
When developing new batteries and battery management systems for electric vehicles, extensive tests and validations are the order of the day. This includes life cycle testing and misuse tests. These can be used to determine the load limits of battery cells, battery modules and complete battery packs. Investigations include charging and discharging cycles in climatic chambers as well as crash loads, penetration, compression, bending and vibration tests. These comprehensive tests require a flexible, automated test system, including data evaluation. The measurement technology acquires data safely and without disturbance in a high voltage environment. SK Innovation, one of the world's largest battery manufacturers, relied on the HV measurement technology from imc Test & Measurement and commissioned several measurement racks for battery tests.
Vehicles must be able to withstand extreme track conditions, such as potholes, ramps, jumps or curbs. Misuse tests are used to evaluate the safety and performance of components under these conditions. When validating the chassis components and the system behavior of the chassis, it is also a matter of checking the threshold values of the control units for passive safety. Using the imc measurement system CRONOSflex, IDIADA in Spain collected data from the vehicle (CAN-FD, Flexray, in-vehicle sensor signals ...) and from additionally installed sensors (accelerometers, gyroscopes, displacement transducers, force transducers, strain gauges ...) during the tests.
The Israeli imc partner MotionTech Ldt. developed a mobile application with the imc CRONOSflex system and imc STUDIO to measure vehicle vibrations for durability testing. This test is largely automated. Integrated real-time data analysis saves time by pre-selecting and processing the measured data.
The new statutory WLTP test cycle requires a consumption measurement for each variant of a new passenger car model. The measurement procedure used by the EU as the standard for consumption values includes a measurement on the test bench and an RDE test on the road to determine realistic values. In order to cope with this test cycle in a time-saving and cost-efficient manner, imc developed a user-friendly and compact measurement box that works both on the test bench and on the road.
The Fraunhofer Institute of Wind Energy and Energy System Technology (IWES) uses the Dx telemetry system in a condition monitoring project at a wind power station. Oliver Schultz, technical staff member of IWES: “The Dx-telemetry system has convinced us due to its minimal space requirements and its good cost-performance ratio.”

Above all, solutions must be implemented for mobile use and as many different signals as possible must be acquired and measured with one measurement device.
imc Test & Measurement GmbH has developed its innovative and compact imc measurement system case especially for this area of application.
For quite some time now, interior noise in cars has been getting quieter. The once dominant sound of the internal combustion engine is now in the background, and other noise sources have moved to the forefront. Due to their high RPM, alternators contribute up to 40% of this total noise inside the vehicle. In order that this noise doesn't become to dominant
or disturbing, imc automated the entire test sequence. The system consists of a modular imc measurement
system and customized software based on the imc STUDIO software platform.
In the modern development of hand-held power tools, the measurement of frequencies and vibrations that can be harmful to humans, as well as determining resonances in rotating tools, plays an increasingly important role.
On the one hand, it is a matter of fulfilling the EU Standard “Noise and Vibration Regulations” (standard measurement procedure according to EN ISO 5349-1/2). On the other hand, it is of great importance to identify weak points in the tool at an early stage by means of order tracking and thus eliminate them easily.
As engines become quieter, certain vehicle components are becoming perceivable which were previously drowned out by engine noise. For this reason, acoustic measurement now faces new challenges.
Finding efficient solutions for the specific requirements of railway technologies is of decisive importance for the manufacturers of railway vehicles. Safety issues play as much of a role as passenger comfort, speed and economic factors.
