Abstract
A test fixture includes a weighted frame incorporating air-filled bellow feet for simulating a vehicle suspension and tires. A hood-simulating support is pivoted to the frame and includes a mount for a grille. A shock absorber on the frame rapidly decelerates the support as the support reaches the closed position. An actuator is operably connected to a controller for closing the support at predetermined speeds for simulating stresses and forces on the grille as seen on actual vehicles. The combination simulates hood closure, including vehicle “bounce” upon hood closure. The controller can be programmed to provide different closure speeds and different air pressures in the feet for better simulation of particular vehicle models. In one form, the fixture includes an enclosure for controlling a temperature of an air fluid source and air for operating the actuator.
