【摘要】 以运载火箭舱段为研究对象，开发了螺纹紧固件力矩施加监控系统，制定了螺栓点位及力矩程序编号规则。通过工艺试验获得了最优的拧紧策略和工艺参数，验证了该系统能够进行人机交互编程，实现力矩施加过程的自动化，实时获得力矩大小及点位数据信息。试验结果表明，采用该系统力矩合格率可达100%，为航天型号产品大尺寸产品稠密点位螺栓力矩的可靠管理提供可靠保证。更多还原

【Abstract】 A monitoring system for the torque application is developed for launch vehicle cabins,and the code rules of the bolt point and the torque program are formulated. The optimal tightening strategy and process parameters are obtained by the process test. The results show that the system can carry out human-computer interactive programming,and realize the automation of torque application process with obtaining the torque size and point data information. The experiment result shows the qualified rate is 100%. The proposed approach realizes the reliable management of dense point bolt torques for large-size aerospace products.更多还原
