Development Of An Integrated Platform For Tire Design Simulation

Tires are important components of vehicles,playing a crucial role in supporting the load,transmitting braking,driving forces to the ground,and providing cushioning and shock absorption.With the rapid development of computers,finite element simulation technology has become widely used in tire manufacturing companies.However,traditional tire finite element analysis relies on manual or handcrafted designs,resulting in long development cycles and low work efficiency.Additionally,traditional tire simulation analysis involves multiple specialized software and complex steps,requiring high levels of engineering expertise.Therefore,developing an integrated platform for tire design and simulation that achieves parameterization,intelligence,and digitization is of significant engineering value.This platform can greatly reduce the difficulty of tire design,improve design and development efficiency,and has important engineering application value.This paper is based on the Python language script interface provided by the Abaqus software and presents the development of an integrated tire design and simulation platform.The platform includes tire parameterized design,efficient finite element mesh generation,and automated post-processing of finite element analysis.The main research work includes:(1)Through exploring the theory of tire structure design and Abaqus secondary development,the development process of Abaqus and the tire structure design and simulation analysis process were deeply integrated,and the structural framework of the integrated tire design and simulation platform was established.(2)The parameterized modeling module for pre-processing in the integrated design and simulation platform was developed,along with an automated mesh division module for complex tire structures.A dedicated plugin was developed using the RSG dialog box constructor,enabling interaction between the Abaqus GUI interface and Kernel internal scripts.This allowed for fast parameterized tire modeling and efficient,high-quality finite element mesh division.(3)A tire finite element simulation analysis result automatic post-processing plugin was developed based on Python language secondary development function of Abaqus software.Users only need to select the odb file to be processed and set the relevant postprocessing result data.All post-processing operations can be completed within a few minutes,and the results will be automatically saved to the specified folder.This avoids a large amount of repetitive manual operations in tire finite element simulation analysis,and the significant efficiency is improved.(4)A full-featured integrated platform for tire design simulation was developed using Python language secondary development technology of Abaqus software.All tire finite element analysis modules are integrated into a single interface,including four modules: tire parameterized modeling module,tire structure mesh automatic partitioning module,tire load and boundary condition application module,and tire simulation result automatic post-processing module.Users only need to input relevant parameters for tire design modeling and simulation analysis to complete the entire finite element analysis.(5)By selecting an engineering simulation case of a certain tire model and testing and verifying the various modules of the design and simulation integrated platform,combined with practical engineering,the calculation results of manual modeling and simulation were compared.The results showed that using the tire design and simulation integrated platform developed in this paper to establish a finite element model,the analysis results are reliable and tens of times more efficient.
