摘　　要：为完成枪械瞄准角变化量测试,提出一种新的高精度枪械瞄准角测试方法。在三维坐标测量机上,选取枪械身管上某一位置作为原点建立坐标系测试瞄准角,解决了传统方法中用平板和调整夹为枪械定位耗时长、精度低的问题。分析了新方法和传统方法的测试原理,经测试误差公式推导发现新方法在理论上累积测试误差更小。通过Solid Works建立枪管仿真模型导入ANSYS划分网格后,将实际试验中测试数据的平均值作为载荷施加于仿真模型上,进行仿真分析,确立了在三维坐标测量机中以枪械身管建立坐标系的原点选取。在验证性试验中,拟合实际测试结果数据发现具有很高的一致性。试验结果表明:新方法在枪械瞄准角实际测试中操作方法简单、精度高,满足枪械瞄准角变化量测试要求。To complete the gun aiming angle variation test, this paper puts forward a new high precision of gun aiming angle test method. In a 3-dimensional coordinate measuring machine, aiming angle is tested by the selection of gun barrel in a certain position as the origin of a coordinate system, and it is solved that time consuming of the traditional method using plate and adjusting the clip for gun positioning and low accuracy problem. The new method and traditional method are compared, and the test error formula is derived to find that cumulative test error of new methods is smaller in theory. The simulation model of barrel built by Solid Works is input into ANSYS and meshed, the mean value of data in practical test as a load is applied to the simulation model and simulated, and origin point selection is made sure with gun barrel fixed in the 3d coordinate measuring machine. In the verification experiment, the actual test results data are fit and the very high consistency is found. The results show that, the new test method of gun aiming angle is simple and precise, and satisfies the requirement of gun aiming angle variation test.
