Testing of new materials, the impact strength: the Institute of lightweight structures for the automotive industry trusts GenesisHighSpeed from HBM
Currently, the car once again re-invented. The new drive concept is not the only thing that can radically change the automotive industry. A crucial role is also played by the use of innovative, namely lighter materials. A range of materials from fiber composites to hybrid and ultra-high-strength materials metallicheskaya share one thing in common: they are all lighter than the cold-formed steel used in the past. It pozvoljaetrealizovat and produce vehicles that are easier and ultimately more economical. Institute of lightweight structures for the automotive industry (LIA), University of Paderborn razrabatyvaet analyzes the concept of lightweight structures using these and other new materials. The Institute carries out quasi-static,cyclic and highly dynamic test series to verify the groups of components and materials.
Own stand for testing materials in impact strength.
LIA has extensive capabilities for comprehensive testing, such as in-house test stand which is suitable for the analysis of impact in collisions speed up to 25 m/s with an energy of 32 kJ. The test stand can be used for deformation analysis of components, testing highly dynamic explosive loads, high-speed testing on squeezing, and more. Two vysokoskorostniye with recording frequency up to 100 kHz are used to analyze the test results.
For effective calculation and analysis of processes of destruction need to:
- to measure the force response of the presser plate or the movable plate, and the curve displacement and velocity at the moment of impact with a moving plate.
Ultimately, the quality of each test stand depends on the used data collection systems. For this reason, the Institute LIA trusts the data acquisition system from HBM GEN record and analyze measurement data. The advantages of this system are its high sampling rate and high level of reliability and speed of data processing in the embedded software Perception.
Data acquisition system GEN
Data acquisition system GEN is a complete, portable test laboratory that includes all the components required for complex measurement tasks. GEN completely provides the entire measurement circuit, including the amplifier input signals, the filter selection of the measuring sequence with adjustable frequency and trigger events, as well as pre-processing, analysis and storage of measuring data.
