摘 要：Based on the mechanics model of 48 V battery under C-NCAP collision condition,the layout under the co-driver’s seat,the three-point fixing scheme and the pull rod constraint structure were *** by using the static theory,the lowcost material strength and plate thickness were *** CAE simulation and C-NCAP vehicle test,the constraint effectiveness of the structure design under the collision condition was *** on this design,about 10 L of luggage space was saved,50% of layout cost was cut down and 1.5 kg of vehicle weight was lightened.
