英文回答：

The Neck Injury Criterion (NIC) is a measure of the

risk of injury to the cervical spine due to blunt impact.

It is used in the design of automotive safety systems and

in the evaluation of crashworthiness. The NIC is based on

the concept of energy absorption and dissipation in the

cervical spine during impact.

The NIC is defined as the maximum compressive force

applied to the cervical spine during impact, divided by the

cross-sectional area of the cervical spine. The NIC is

expressed in units of newtons per square meter (N/m2).

The NIC is calculated using a finite element model of

the cervical spine. The model is subjected to a dynamic

impact load, and the maximum compressive force and cross-

sectional area of the cervical spine are determined. The

NIC is then calculated by dividing the maximum compressive

force by the cross-sectional area.

The NIC is used to assess the risk of injury to the

cervical spine in a variety of applications, including:

Automotive safety: The NIC is used to design

automotive safety systems, such as airbags and headrests,

to reduce the risk of injury to the cervical spine in a

crash.

Crashworthiness evaluation: The NIC is used to

evaluate the crashworthiness of vehicles, and to compare

the safety of different vehicles.

Injury prediction: The NIC can be used to predict the

risk of injury to the cervical spine in a crash, based on

the magnitude and direction of the impact.

The NIC is a valuable tool for assessing the risk of

injury to the cervical spine. It is used in the design of

automotive safety systems and in the evaluation of

crashworthiness. The NIC can help to reduce the risk of

injury to the cervical spine in a crash.

颈部损伤指标 (NIC) 是衡量颈椎由于钝性冲击而受伤风险的指

标。它用于汽车安全系统的设计和碰撞适性的评估。NIC 基于冲击

过程中颈椎的能量吸收和消散的概念。

NIC 被定义为冲击过程中施加于颈椎的最大压缩力，除以颈椎

的横截面积。NIC 的单位为牛顿/平方米 (N/m2)。

NIC 是使用颈椎的有限元模型计算的。该模型承受动态冲击载

荷，并确定颈椎的最大压缩力和横截面积。然后通过将最大压缩力

除以横截面积来计算 NIC。

NIC 用于评估各种应用中颈椎的受伤风险，包括：

汽车安全，NIC 用于设计汽车安全系统，如安全气囊和头枕，

以降低碰撞中颈椎受伤的风险。

碰撞适性评估，NIC 用于评估车辆的碰撞适性，并比较不同车

辆的安全性。

损伤预测，NIC 可用于根据冲击的大小和方向预测碰撞中颈椎

受伤的风险。

NIC 是评估颈椎受伤风险的宝贵工具。它用于汽车安全系统的

设计和碰撞适性的评估。NIC 有助于降低碰撞中颈椎受伤的风险。
