Stiffnesses
Damping behaviour of the components

Effects:

Can cause resonances and dynamic problems
Affect the service life of the components

Influencing factors:

Some parameters are influenced by environmental conditions

Significance:

An in-depth investigation of the interactions between the individual components is essential

Development objective:

Noise reduction in clutches, gearboxes and drive shafts

Multi-channel speed measurement and vibration analysis

Multi-channel speed measurement is carried out using magneto-resistive sensors and laser sensors at typical measuring points such as cardan shafts (KW), drive shafts (AW), clutches (K0, K1), electric motors (E0-E4) and gearboxes.
In combination with analogue measured variables such as acceleration and sound pressure, a comprehensive overall picture of the vibration behaviour of the drivetrain is created.

The recorded measured values are evaluated in both the time and spectral domain, which also allows the acoustic behaviour of the system to be analysed.

Frequently Asked Questions

Have Question? We are here to help

What does the ROTEC solution for rotation analysis look like and what does RAS mean?

The ROTEC Rotational Analysis System (RAS) has been used for more than 30 years by users in the mechanical engineering, automotive, power generation and motorsport industries to comprehensively analyse rotating components.

With its unique measurement method using a 12.3 GHz counter card and a strictly angle-based approach to rotational speed detection and analysis, the RAS system offers users an unrivalled advantage.

ROTEC offers not only optical and magnetic speed sensors including signal conditioning adapters, but also the modular measuring system RASdelta as well as specialised and user-friendly software for measurement and analysis. This enables a complete solution from a single source. The ROTEC measurement technology products are perfectly harmonised and deliver meaningful results within a very short time after the uncomplicated setup of the measurement chain.

Thanks to the angle-based approach to speed measurement, problems such as sensor vibrations can be recognised after the first measurement and rectified immediately. This effectively prevents costly incorrect measurements.

Our team of experts at ROTEC ENGINEERING, consisting of long-standing users, will be happy to assist you with challenging tasks.

Are there options for customising the measuring systems and software?

The ROTEC RASdelta front end is a versatile modular measuring system that can be individually configured with 8 or 16 measuring cards to meet your specific measuring requirements.

Our RAS software offers you a comprehensive modular system for analysing rotating components and complex systems. It is an effective tool for mechanical engineers and requires no programming knowledge to perform measurements or analyses.

If you have specific metrological questions, our experienced ROTEC ENGINEERING consulting team will be happy to support you.

Does ROTEC offer other services in addition to the measuring systems, e.g. customised consulting or project support?

ROTEC not only offers speed sensors, signal conditioning, measurement systems (DAQ) and measurement and evaluation software, but also engineering and consulting services.

Our services include the design of measuring points in CAD, the mechanical processing of components, the application and calibration of sensors, the execution of measurement tasks and the evaluation of measurements according to our customers' requirements, including the presentation of the results. The ROTEC ENGINEERING team can also realise sub-projects as part of project support.

Is there training or technical support for commissioning and integrating the measuring systems?

In addition to our annual ROTEC Training Week, which is held in both German and English, we also offer customised training courses for users. These training courses are specially tailored to your individual application of the ROTEC measuring system and include practical demo measurements in your environment in addition to the theoretical basics and a detailed presentation of the software. This ensures that future users are optimally prepared for your specific application.

Furthermore, we are happy to support you in the commissioning of new measuring systems to enable you to familiarise yourself with the settings and possibilities of the RAS software as quickly as possible.

How is support ensured and are there self-help options?

In addition to our sales and support team in Munich, which serves the Central European market directly from here, ROTEC also cooperates with local partners in many global markets. These partners support local users in all matters relating to ROTEC measurement technology, first-level support and sales enquiries with trained personnel.

Our customers around the world appreciate the proximity of our sales and support teams, as this enables us to guarantee effective support even for short-term questions.

In addition to personal contact, ROTEC also offers an extensive knowledge database for self-help. Please register for our knowledge database to obtain detailed information on measuring and analysing torsional vibrations, transmission errors and valve systems, among other things.
