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
