摘要
通过分析多质点称量法与不平衡力矩测质心法,针对本质心测量系统的工作特点,以天平原理与不平衡力矩理论为依据,对高精度质心测量方法进行了探讨。采用十字刀口与升降台结构和称重传感器技术,汲取上述两种方法的优点,形成新型测量机构与方法。利用Visual Basic软件设计了控制系统的操作界面,解算出质心测量系统的算法方程,得到所求物体的质心偏心距与不平衡力矩,并进行了误差分析。结合现有的形心测量技术,研制了一种新型的质心测量系统。
To analyse the centroid measuring method of multi - point weighing and unbalance rules, in view of the working characteristic of the measuring system, based on principle and unbalanced moment balance theory, a high precision measuring method of centroid is developed. Adopt cross incision and lifting platform structure and weighing sensor technol- ogy, absorbed the advantages of the above two methods, form a new type of measuring mechanism and method. Calculating the centroid algorithm equations of measurement system by using Visual Basic software design of the control system inter- face, obtain the required object centroid eccentricity and unbalanced torque, then analyze the error. Combining with the ex- isting shape center measuring technique, a new type of centroid measurement system is developed.
