Fatigue strength of stabilizer bars
Relevant influences
- Mechanical loading as a result of
- Bar torsion
- Axle kinematics
- Corrosive environmental conditions
- Damage to surface and coating caused by stone impact
Experimental verification
- Pre-damage caused by stone impact
- Corrosion in alternating cycle tests developed by the German Association of the Automotive Industry (Verband der Automobilindustrie, VDA)
- Tests with original stabilizer bars in installation position
- Optional tests with simulated compression kinematics on full axle configuration
- Vibration fatigue tests with fixed or variable amplitudes
- Statistical validation with systematic testing and a sufficient number of test items
