Environmental Simulation and Vibration testing – We can create the environment in the laboratory for you

Our engineers can provide you with extensive experience in the field of environmental simulation, where real measured external influences such as vibration, shock, cold, heat, moisture, or splashing water can be mapped on vibrating tables and in climatic chambers.

There is a vast field of work for you between development, quality assurance and the approval certification in all industries, including vibration testing, shock testing, climatic testing, Wöhler curve evaluation, pressure impulse testing, burst pressure testing, leakage testing, corrosion testing and transport simulation. A probit test, stair step process and a test for fuel resistance complement the portfolio.

We evaluate via experimental paths in order to verify the reliability of your product dynamic characteristics such as resonances, spring coefficients, damping variables as well as mass distributions. We will be pleased to monitor your technical equipment permanently on request (including data evaluation such as frequency analysis and estimation of the operating strength).

As an accredited test service provider, we not only provide standard-compliant component examinations but also, as an additional benefit, the flexible accreditation provides us with the opportunity to modify and to develop new test procedures.

Vibration testing

We can test your products, components and assemblies in our modern vibration laboratories as standard compliant for their behaviour and reliability in the event of vibration and shock loads. Our laboratories are equipped with electro-dynamic shakers for 9 KN up to 60 kN forces with sliding table as well as a transportable climatic chamber for simultaneous temperature and humidity loads for the test specimens.

Would you like to have vibration and shock tests under climatic influences? We simulate loading conditions in a wide temperature and humidity range. Development-supporting product validations include additional testing methods such as pressure impulse testing, burst pressure tests, leakage tests e.g. in the case of fuel rails.

Multiaxial vibration test with/without thermal loading

For operating load simulation for transport stress, we utilise a shaker test bench within the framework of the operating strength examination for the automotive industry, whose main components are a multi-axle oscillation table (MAST) and a combinable hot gas generator.

This test equipment is particularly suitable for testing components, modules, assemblies and subsystems such as, for example, tanks, attachment and dismantling parts, exhaust systems, roof and rear-mounted carrier systems, front-end modules, cooling systems and much more.

Utilising the multi-axial oscillation table (MAST) makes it possible to generate the loads from mechanical oscillations as regulated, whether for the simulation of the operating loads such as unevenness on roads, steering and braking loads, load interchanging and vertical and roll motions.

Exhaust systems and exhaust gas-carrying components are, for example, subjected to complex load conditions due to their function and location within the vehicle. On the one hand there are strong thermal-mechanical stresses due to the temperature of the exhaust gas. Meanwhile, these components have to withstand mechanical vibration loads arising from the motion of the vehicle and motor vibration impulses. The hot gas generator is capable of generating variable thermal-mechanical loads for components. Combining both systems allows the overlaying of stresses through experimental simulation. Both systems can be operated independently of each other.

Pressure Pulse test

We can execute pressure pulse testing, leak tests, burst pressure tests on hydraulic components, pipework, fittings, fixtures, fuel lines, injection systems and rails. This enables the pressure pulse strength to be tested with indoor dynamic tests. Combining pressure pulse tests and vibration tests in accordance with IACS and DNVGL Type Approval also enables hydraulic fittings to be tested for bending with loads for internal pressure.

Certification tests for hydraulic systems are just one part of our testing spectrum as well as comprehensive validation inspections e.g. for fuel rails.
