Study on Laser Thermal Loading Test with Non-Symmetric and Non-Uniform Shaped Laser Beam
The key point of laser thermal loading test is to simulate the real temperature field on the top surface of the cylinder head with an easy,controllable,effective and accurate way.A kind of non-symmetric and non-uniform shaped laser beam is chosen as the heat source to irradiate on the top surface of the cylinder head,the simulated temperature field is consistent with the real one.The high cycle and low cycle thermal loading tests are realized.The test results show that the thermal loading tests can be effectively carried out with the temperature and time control models,which can provide the foundation for the fatigue life prediction.
