CARoLINE in the End-of-Line Test
CARoLINE has been developed for the evaluation of the assembly quality and function of electromotive vehicle components.With the help of statistical analyses and the evaluation of acoustic properties you can improve manufacturing and assembly processes. These methods are provided by the acoustic system CARoLINE. With simple parameters, complex methods such as pulse valuation, order filter or scaling are adjustable.
Via scatter diagrams/spread patterns you can test the parameters and adapt the manufacturing process.
Impact Sound Analysis
To evaluate the quality of rotating, motor-driven components in the vehicle, impact sound analyses became more and more essential. Besides the reduction of noise, it is helpful to identify noises to evaluate the quality of manufacturing.
The system for impact sound analysis consists of impact sound sensors, modules for data entry and installed evaluation software.
These sensors are attached by metallic brackets, magnets or directly to the motor-driven units under test.
GOEPEL electronic chooses the adequate sensors for impact sound measurement together with you and advises you on the integration into the equipment.

The software is modularly configured. Thus, the software system is able to execute all analysis processes in parallel.
The trigger conditions and parameterization of the single calculations and evaluations are handled in the inbound data stream by the data server in parallel processes. Thus, you as the user can arrange several process steps in parallel running modules and parameterize your test procedures.
In freely definable frequency bands, the levels are controlled. The integrated digital band filters evaluate the acoustic signals and split them into different frequency ranges. An editor is available to edit the test processes.
Typical acoustic methods with CARoLINE
- evaluation of single or combined frequency bands, including octave or one-third octave analysis
- order analysis, also combined
- rotary speed analysis from the resonance signal or ripple power signal of the motor to be used in the order analysis or for modulation analysis
- statistical analysis for process control
