上升离位触点 - In this paper , to counter a flexible beam undergoing large overall motion impacting a fixed slope surface under the effects of grativity , the normal contact model is established based on the hertz theory and non - linear damping term , the tangential contact model is developed by adopting linear tangential contact stiffness to consider the effects of friction force during impact process , and the consistent linear dynamic model including impact is derived by using mode assumption method and lagrangin equation
针对在重力场下作大范围回转运动的柔性梁与一固定斜面发生斜碰撞的情况，根据hertz接触理论和非线性阻尼项建立法向碰撞接触模型。引入线性切线接触刚度建立切向碰撞接触模型，以考虑接触过程中由于切向相对速度的换向作用引起的摩擦力的变化。利用假设模态法和lagrangian方程建立系统含碰撞过程的一致线性化的动力学模型。 - The new technology of non - contact life - parameter detection is relative to that of the normal contact one , which uses microwave beams to illuminate the human subject , whose reflected wave will be modulated by the surface movement resulting from the physical activity . by this way , some parameters of the reflected wave , such as frequency and phase will be changed . if these changes can be detected , the life parameters such as respiration rate and heartbeat rate will be extracted from those changes
非接触生命参数检测是相对于常规的接触式检测而言的一种新技术，它利用微波束照射人体，其回波信号被人体生命活动引起的体表微动所调制，使得回波信号的某些参数(如频率、相位)发生改变，检测到这些变化就能从中提取出人体的生命参数(如呼吸或心跳) 。
