摘要： A noise damper, annulus for reducing tire noise, and tire and noise damper assembly are disclosed. The noise damper, annulus for reducing tire noise, and tire and noise damper assembly mitigate sound produced by a moving tire. The noise damper and annulus for reducing tire noise may move within a tire cavity.

摘要： A method and apparatus for predicting the shape of a contact region of a finite element model deformed against a contact surface. The contact surface may be a rigid body or another finite element model. The shape of a contact region is dictated by the node/element distribution in response to a simulated load. This procedure uses curve fitting to predict the boundary of a contact region for a specified load condition based upon an analysis of contact region shapes generated by finite element analysis for each load within a range of simulated loads. In this manner, the discrete nature of the contact region boundary associated with finite element analysis results at a single load is overcome using information derived from previous load simulations. The approach improves the accuracy and resolution of simulated contact shape boundaries without a corresponding increase in processing resources.
