High-precision Rotational Speed Centrifuge Test System of Fuze Security Agencies

高精度转速大型离心机是用于引信安全执行机构测试的专用设备,针对引信安全执行机构过载环境下解除保险测试过程中,直径大于1 m的离心机转速精度不满足现有测试需求的情况,提出一种引信安全执行机构测试用大型离心机的设计。通过对离心机控制系统电机、支撑座及刚性轴的改进设计,增强了离心机强度、动平衡和轴系精度,实现了高精度转速引信测试用大型离心机的研制。建模和仿真测试结果表明,离心机回转速率精度和速率稳定性从10^(-3)提升到了10^(-4)数量级。

The high-precision rotational speed large centrifuge is a special equipment for the security agencies test of the fuze.In order to solve the problem that the high-precision rotational speed centrifuge with a diameter greater than 1m does not meet the existing test requirements during the overload test of the fuze security agencies,a design of a large centrifuge for the test of the fuze security agencies is proposed.Through the improved design of the centrifuge control system motor,support seat and rigid shaft,the strength,dynamic balance and shafting accuracy of the centrifuge are enhanced,and the modeling and simulation are carried out,the development of a large centrifuge for high-precision rotational speed fuze test was realized,and the test results showed that the design method was effective,and the accuracy and rate stability of the centrifuge rotation rate were improved from the current 10^(-3) to 10^(-4) orders of magnitude.
