Summary:

The verification of the durability for vehicle body and chassis components is a basic requirement for the vehicle development process. For this, automotive company performs durability test on the proving ground or predict the durability using CAE technology. The representative proving ground test that verifies the durability of vehicle body and chassis components are belgian(hereinafter B/G) and cross-country(hereinafter X/C) test road. The B/G test road verifies the durability of body and chassis components for periodic road load that the vehicle undergoes while travelling on a rough road with regular speed. The X/C test road is composed of squat, dive, bumping and bottoming test modes and this test verifies the durability under aperiodic road load. Because of the relatively long test load of X/C, the road load signal of X/C is too long and enormous to apply it to durability analysis. So, the vehicle durability analysis for the proving ground has been performed only for B/G road test condition. In this research, a new process for numerical analysis of squat and dive event which occur during the braking test mode of X/C durability test is established based on the correlation results between the numerical results and test results. And the application of this technique to predict the fracture of front suspension of FR type vehicle was successful
