| Tires are important safety part of the automobile.Tires make contact with the ground and transfer the driving force,braking force and steering force,which affects the NVH performance,comfort and control stability of the vehicle.There are three important components of tire design: pattern,structure and compound.The structure design can influence the tire's footprint and grounding pressure distribution,affect the tire's stiffness,and thus affect the driving performance and braking performance of the whole vehicle.The structure design can influence the tire's footprint and pressure distribution,which can affect the wear status of tires and further affect the service life of tires.The tire structure design can influence the stiffness of the tire,which can influence the control stability and ride comfort,as well as the NVH performance of the vehicle.The structure design has a direct impact on the high-speed performance,durability,bead unseat and strength performance of the tire.Each performance is closely related to the safety of the tire,which is directly related to the safety of the car.This work mainly includes the following contents: firstly,introduce the development history of tires and the role of tires.At the same time introduce the method of structure design and the function of each component.Then,this paper studied the impact of structural design factors on the performance of tire and the overall performance of the vehicle,and mainly selected the following performance for research and description: tire footprint pressure distribution,static stiffness,noise,durability,overall dimension,NVH for the whole vehicle.The design parameters of the tire structure mainly include the angle of the belts,the height of the apex rubber,and the cap ply.We can accumulate design experience for future product design and optimization through the research on the influence of the structural design factors of the tire.The last part gives the conclusion and prospect of the paper. |
