Computer simulation of the new ring seal coaction in combustion engine
A computer simulation which as model loads uses program KIVA 3 for combustion engine work process (combustion chamber heat flux, pressure and temperature) computations has been developed. It makes it possible to compute the pressure and temperature distributions and the motion of the charge in the combustion chamber at a particular point in the work cycle. Computer models of the ring seal components were constructed using computer code Parasolid v. 11. The models render to the finest detail the design-material features of the ring seal components. The Nastran program was used to perform FEM computations for a selected point of engine work (at a crank angle of 10?) at which the maximum averaged temperatures and pressures were found to occur in the combustion chamber. Finally, 3D temperature and pressure distributions for the whole ring seal were obtained. On their basis, inferences can be made about the design-technological nature of the seal under development.
