| Abstract: | This paper analyzed the problems of large acceleration and excessive intrusion of local body in frontal impact development of a left-hand vehicle.The reason analysis was carried out by means of simulation.Aiming at the defects of body structure and engine room layout,the effective improvement scheme was put forward.Optimized car body acceleration and body intrusion was improved.The acceleration had been reduced from 51.2g to 39.5g,and the intrusion had been reduced from 78mm to 40mm.The results showed that after optimizing the problem of crash among transmission and sub frame and installation point of the body,and coordinated with optimization of the deformation mode of the longitudinal beam.All the indexes met the C-NCAP 2021 five-star target requirements. |
