【摘要】：陀螺仪作为高精度敏感元件,其生产制造过程中的静平衡工序是必不可少的环节。现有的陀螺仪浮子的静平衡技术,测量过程中浮子处于非自由的转轴支撑状态,测量过程多需要人工重复操作,生产效率较低。为此,本文提出了针对圆筒形液浮陀螺仪浮子在全液浮状态的不平衡量测量方法,并设计了静平衡机装置。首先结合陀螺仪浮子结构,根据力学定律,提出了不平衡量测量方法的方案步骤,建立了不平衡量测量数学模型,采用了正交基变换方法解算数学模型,给出了状态空间表达式,分析了系统的性能,构建了浮子的去重约束方程组,利用单纯形法给出了去重的最优化解,进行了陀螺仪静平衡装置的软件和硬件设计,利用了亚像素边缘检测技术采集浮子在浮液中的姿态信息,进行了仿真实验,验证了陀螺仪浮子不平衡量测量方法的有效性和可行性。
[Abstract]:As a sensitive element with high precision, gyroscope is essential to the static balance process in the manufacturing process. The existing static balance technology of gyroscope float is in a non-free rotating shaft support state during the measurement process. The measurement process often needs manual repeated operation, and the production efficiency is low. In this paper, a method for measuring the unbalance of the float of cylindrical liquid gyroscope in the whole liquid floatation state is put forward in this paper. The static balancing machine is designed. Firstly, combining the structure of gyroscope float, according to the law of mechanics, the scheme and steps of measuring unbalance quantity are put forward, and the mathematical model of measuring unbalance quantity is established. The mathematical model is solved by orthogonal basis transformation method, the expression of state space is given, the performance of the system is analyzed, the equations of de-reconstraint of float are constructed, and the optimal solution of removing heavy is given by using simplex method. The software and hardware design of gyroscope static balance device is carried out, and the attitude information of float in floating fluid is collected by using sub-pixel edge detection technology, and the simulation experiment is carried out. The validity and feasibility of the measurement method of gyroscope float unbalance are verified.
