摘　　要：因设计需要须对安全带敏感机构上的某点进行加速度分析,文章首先根据平面运动学动点的线加速度矢量定义推导了该点的加速度,再利用平行轴的角加速度叠加原理对该点进行了加速度的分析,两种方法得到的结果相同。对该点的加速度分析为后续进行安全带敏感机构的动力学分析打下基础、也为平行轴的角加速度叠加原理提供了实例验证。To meet the design needs, the acceleration analysis of a point on the sensitive mechanism of a safety belt is carried out in the paper. The acceleration of the moving point of the plane kinematics is derived from the definition of the linear acceleration vector, and the acceleration at the point was also analyzed by using the superposition principle of angular velocity acceleration of the parallel axis. The two methods achieve the same result. The acceleration analysis at this point not only lays a foundation for the subsequent dynamic analysis of the safety belt sensitive mechanism, but also provides an example to verify the principle of angular acceleration superposition of parallel axes.
