Analysis and computer simulations of some mechanical movements relating to jerks;
关于加加速度的若干机械运动分析及MATLAB模拟
In recent years,researches indicate that the derivative of acceleration(jerk,m/s3),which is directly proportional to the force changing rate,has close relation with the physical destruction process and can be applied to many fields of modern development.
近几年的研究表明,加速度的微分量(即加加速度,单位为m/s3)与力的变化率成正比,与物理破坏过程有密切关系,在现代技术的发展中有着很多应用,如高动态运动飞行器的跟踪测量、结构抗震新机理研究、高速机械加工的自动控制、高速列车和电梯舒适度的测量、通信设备的抗震性能检测均需要加加速度参量的测量,加加速度的精确测量和加加速度计的研制愈来愈引起工程界的重视。
