Outline
To address the high-voltage electrical safety risk of a hybrid SUV during 80 km/h rear impacts as specified by FMVSS 305, component-level investigations are conducted, and vehicle collision structure optimization is performed. At the component level, through designing two types of component tests, quasi-static extrusion and dynamic impact, the ultimate bearing capacity of Intelligent Power System (IPS) is obtained. At the level of vehicle collision structure optimization, by optimizing the rear impact force transmission path and improving the IPS collision mode, designing the rear longitudinal beam structure to bend upward makes IPS be subjected to planar extrusion. The simulated IPS collision force decreases by 64% from 137 kN to 49 kN, which is less than its ultimate bearing capacity.
