High-cycle fatigue is responsible for a majority of cylinder head cracks. Southwest Research Institute (SwRI) Engine Design engineers have developed a component test rig useful for quickly and inexpensively identifying potential high-cycle fatigue failure sites.
Fatigue Rig TestingThe rig test utilizes hydraulic pressure to simulate alternating cylinder pressure loading. A mean thermal load can also be incorporated in the test. When combined with historical product field failure data, the rig test can be a significant part of an overall evaluation program.
