Piquing the interest of many powertrain engineers at the 2016 Engine Expo is the adjacent Automotive Testing Expo, now in its 18th year. One exhibitor that appeals to a wide variety of visitor to the Stuttgart Messe is Weiss Umwelttechnik GmbH.
The German supplier is using the event to showcase its range of test chambers, which are used to test Li-ion batteries, as found in hybrid and EV vehicles. Weiss’ chambers can be used to simulate vibration and environmental conditions on a variety of battery types.
January 2015 saw Germany’s leading analysis and test services company, IABG install such a test cell at its facilities. This multiaxial Shaker allows very complex vibration tests under the influence of targeted environmental simulation (temperature and humidity).
The ‘Light Multi Axis Shaker” (LIMA)’ is a hydraulic hexapod system with six degrees of freedom and is suitable for vibration tests of 0.5 to 200Hz with acceleration up to 130m/s. By multiaxial suggestions vibration loads can be simultaneously modeled or simulated in all translational and rotational degrees of freedom over a wide frequency range. The integration of the system into a climatic chamber also allows to combine the mechanical tests with a simulation environment at temperatures of -40°C to +95°C and a humidity of up to 95% relative humidity.
