Use of Simulation Tools in EGR Development Process 2001-01-1747

During the development process of the EGR, several CAE tools were used. The overall load results as a combination of static, dynamical and temperature induced load. The inputs were known from experiments and engine test stand. The influence of different gasket assembly possibilities onto the pre-stress in the structure was subject to several static analysis. The dynamic behavior was addressed because of the engine induced random vibrations into the EGR system. Natural frequencies and modes were used to show potential for improvements and power spectral density analysis was used the evaluate the statistical stress distribution. Fluid distribution and structure temperature was obtained from CFD analysis with conjugate heat transfer.
