The invention provides a hood assembly, a manufacturing method of the hood assembly and a vehicle. The manufacturing method of the hood assembly comprises the steps that distribution of damage values of the hood assembly to pedestrians is calculated through a computer simulation program, and the higher the damage value is, the heavier the injury degree of the pedestrians is; calculating an average damage value formed by the hood assembly according to the damage value distribution; judging whether the average damage value is lower than or equal to a reference value; if the average damage value is higher than the reference value, an elastic piece is arranged between an inner plate and an outer plate of the hood assembly; and re-calculating the damage value distribution of the hood assembly, and repeating the steps until the average damage value is lower than or equal to the reference value. Compared with an existing hood, the hood assembly can absorb larger collision energy so that pedestrians can be better protected, an existing active hinge can be replaced, and therefore the manufacturing cost can be saved.

    本发明提供了一种机罩总成、机罩总成的制造方法和车辆,机罩总成的制造方法包括:通过计算机仿真程序计算机罩总成对行人的伤害值分布,其中,伤害值越高,行人受伤程度越重;根据伤害值分布计算机罩总成形成的平均伤害值;判断平均伤害值是否低于或等于基准值;若平均伤害值高于基准值,在机罩总成的内板与外板之间设置弹性件;重新计算机罩总成的伤害值分布,并重复上述步骤至平均伤害值低于或等于基准值。根据本发明的机罩总成相比现有的机罩可以吸收更大的碰撞能量,从而可以更好地保护行人,并且还可以替代现有的主动式铰链,因此能够节约制造成本。
