    • An active material hood impact mitigation mechanism is activated in response to a signal generated from an impact sensor or pre-impact sensor or manually. The mitigation mechanism is capable of changing either reversibly or irreversibly the stiffness, shape, location, orientation, or displacement force of the hood either globally or locally, before an impact against the hood. The active material mitigation mechanism is held in a device designed to be installed in operative communication with the hood surface. The active material is characterized by a first shape or stiffness and is operative to change to a second shape or stiffness in response to the activation signal. Such active materials include shape memory alloys, electroactive polymers, shape memory polymers, magnetic shape memory alloys, magnetorheological fluids, magnetorheological elastomers, electrorheological fluids, and piezoelectric materials.
    • 响应于从冲击传感器或预冲击传感器产生的信号或手动地激活活性材料罩冲击减轻机构。 缓解机制能够在对机罩的撞击之前全面地或局部地改变发动机罩的刚度,形状,位置,取向或位移力。 活性物质缓释机构保持在被设计成与罩表面操作性连通的装置中。 活性材料的特征在于第一形状或刚度,并且可操作地响应于激活信号而改变为第二形状或刚度。 这种活性材料包括形状记忆合金,电活性聚合物,形状记忆聚合物,磁性形状记忆合金,磁流变流体,磁流变弹性体,电流变流体和压电材料。
