Fatigue strength of valve springs
Relevant influences
- Mechanical loading as a result of compression
- Very high number of load cycles
- Increased temperature
- Dynamic settling Experimental verification
- Tests with maximum stress almost to block length of the spring
- Vibration fatigue tests with fixed amplitudes
- Simultaneous testing of a high number of valve springs
- Simulation of increased temperature
- Statistical validation with systematic testing and a sufficient number of test items
- Determination of dynamic settling
