摘要
由于军事工业和现代交通的快速发展,使机械的运转和行进的速度加快,加速度的变化率即加加速度,引起了关注.举例对加加速度进行了计算和讨论,其结果显示:在全球定位系统(GPS)、高速列车、高速电梯、交通事故分析等,忽略了加速度的变化率,所进行的分析和计算是不完备的.
Because of rapid development in the military industry and modem commtmication, the motion velocity of the mechanism is sped up. The derivative of acceleration, namely, the jerk, should be given more attention. The calculation and discussion are performed for the jerk with some examples. The results show that in GPS, high-speed trains, high-speed elevators and communication accident analyses, these calculations and discussions are not perfect with neglecting the derivative of acceleration.
