Contact analysis and optimization of a poppet valve with seat deformation and friction

Research output: Contribution to conferencePaperpeer-review


The contact pressure between a poppet valve and its seat is an important consideration for valve performance. The geometry of the contacting surfaces is optimized to achieve maximum uniformity in the contact pressure distribution. A general contact algorithm for point-to-cubic sliding contact is presented and verified. It is then used to optimize the valve geometry. The poppet valve and seat are modeled as axisymmetric components.
