Spring testing services for spring manufacturers and car makers

IABG is the leading testing provider for spring testing. Our portfolio covers the pre-conditioning, the cyclic test and the root cause failure analysis. We bring the real world of the spring into our lab. In this matter we reproducibly simulate the surrounding climate conditions and the mechanical damages like stone chipping. The cost and time efficient cyclic test empowers you for quick spring development and quality assurance.

We are able to perform any spring test according to all spring test specifications of the spring and car makers. To assure the most efficient test run we have engineered and designed our own IABG test benches which are well known all over the world to all spring and car makers.

The bullet points for experimental verification are:

• Pre-damage caused by stone impact
• Corrosion in alternating cycle tests developed by the German Association of the Automotive Industry (Verband der Automobilindustrie, VDA)
• Optional tests with simulated compression kinematics
• Tests with original spring seats in installation position
• Vibration fatigue tests with fixed or variable amplitudes
• Abrasive wear simulation
• Corrosion simulation with intermittent salt-water spray exposure
• Statistical validation with systematic testing and a sufficient number of test items
