擒纵式高楼逃生机构利用擒纵轮与擒纵叉的交替啮合,均匀释放人体的重力势能,使人体以一定的平均速度安全降落到地面。进行了该装置的传动方案设计,完成了擒纵机构的参数设计和结构设计。对擒纵机构建立了动力学分析的数学模型,证明了高楼逃生人员的下降速度与人体质量的平方根成正比,与擒纵叉及平衡摆转动惯量的平方根成反比。并针对人体下降速度为2 m/s的情况设计了平衡摆的转动惯量。
Escapement escapement escapement using escapement and escapement fork alternating engagement, uniform release of the body’s gravitational potential, so that the human body to a certain average speed safely landed to the ground. The design of the transmission scheme of the device was completed, and the parameter design and structure design of the escapement were completed. The establishment of a kinetic analysis of the escapement mathematical model to prove that the descent speed of high-rise escapes is proportional to the square root of the human body mass, and pallet fork and balance the moment of inertia square root inversely proportional to. The moment of inertia of the balance pendulum is designed for the case of the human body descending speed of 2 m / s.
