Embodiment Construction

[0019] figure 1 A block diagram of an exemplary finite element analysis (FEA) processing system 100 is shown. FEA processing system 100 may include a computing device 101 housing a processor 102 and a computer-readable medium 104 . A user interface 106 , such as a keyboard, mouse, or other such device, is connected to an input controller 108 that allows a user to interact with the FEA system 100 , including with the processor 102 and the computer-readable medium 104 . Output controller 110 may receive information from input controller 108, processor 102, and / or computer-readable medium 104 for presentation to a user via output device 112, which may take the form of, for example, a video monitor or a printer. The computer-readable medium 104 may take the form of, for example, a hard drive, a solid-state drive, or a read-only memory (“RAM”), and may provide information to any component of the FEA processing system 100 . Network controller 114 allows FEA system 100 to communica...

Abstract

An apparatus and method are disclosed for modeling at least a portion of a rolling tire (200). A finite element model of at least a portion of a tire (200) rolling against a tire contacting surface (202, 506, 602) is input into a finite element analysis system (100). The system executed instructions that result in the application of a constant force to the model tire (200) or portion thereof by the tire contacting surface (202, 506, 602). The application of force control boundary conditions, as opposed to displacement control, provides significant benefit in terms of computational time of the finite element analysis solution. A finite element analysis simulation of the model against the tire contacting surface (202, 506, 602) is performed while maintaining the force on the model tire (200). Alternatively, a camber (gamma) is also applied to the tire and maintained throughout the simulation.

Description

technical field [0001] The present disclosure relates to computer modeling of rolling tires, including through finite element analysis. Background technique [0002] The computational resources required to perform a finite element analysis of a tire are considerable. Simulations of rolling tires on road surfaces are particularly costly in terms of the computing resources required to perform such simulations. Contents of the invention [0003] Apparatus and methods for modeling rolling tires are disclosed. A finite element model of at least a portion of a tire rolling on a road surface is input into a finite element analysis system. The system executes instructions that result in the application of a constant force between the tire or a portion thereof and the road surface. A finite element analysis simulation of the model on the road surface is performed while maintaining the force on the tire. Alternatively, camber was also applied to the tire and maintained throughou...
