Experimental and Numerical Study on Ballistic Impact Response of Vehicle Tires

Tires are a critical component of military wheeled vehicles and exposed to the threat fragment caused by explosion warhead on battlefield. To study ballistic impact response vehicle tires under fragment, experiments numerical simulations spherical fragments impacting were carried out. The damage mode was analyzed. effects obliquity, tire thickness, mass dynamic tires, as well limit velocity, results indicate that: (1) main failure modes comprise local erosion near center perforation, elastic deformation surrounding tensile fracture steel cords. (2) process penetration into can be divided four stages: entry stage, stable cord layer exit stage. (3) structure demonstrates its ability undergo plastic certain extent restraining effect rubber.
