摘要
速度和加速度的实时测量在机械工程和土木工程中都有十分重要的意义。本文对一种新型的速度和加速度测量方法进行了研究。该方法可以实现二维速度和加速度的多点实时测量。该方法的主要原理是设计一种平面坐标检测杆,检测杆可以实时测量出杆上各点的坐标。坐标对时间数值差分可以计算出速度和加速度。将坐标检测杆精确牢固附在被测构件上进行测量。在编写了基于本方法实时计算并直观显示速度和加速度的程序后,本文以一个示例演示该方法。比较了理论解数据与该方法模拟测量数据,两者较为吻合。
The real-time measurement of velocity and acceleration is very important in civil engineering and mechanical engineering.A novel two-dimensional velocity and acceleration measurement method is presented.The velocity and acceleration of multipoint can be measured through this method real-time.The basic principle of this measurement method is to design a plane coordinate detection pole.The pole can real-time detection plane coordinates of all points on the pole.Coordinate detection pole attached to the tested components to be measured.The velocity and acceleration can be got by difference method.The program that can real-time compute and display velocity and acceleration was written.An example was cited to compare theoretical data and simulated measured data.It gave a good agreement between the two data.
