| Abstract: | This paper uses the finite element method to analyze and solve a car hood slamming failures. A hood closing speed which including most customers operation condition was determined by test, Interference of front hood and grille was discovered by test of closing hood, and it was recovered by the finite element method. At the end simulation and verification was carried out with the new bumper mounting case, the car hood slamming failures was solved availably. |
