Study on Digital Process Technology of Bolt Tightening Loading Based on MATLAB–GUI

为解决基于扭矩法的航空发动机螺栓拧紧过程中紧固力分散程度大的问题,探索出更便捷、更高效的螺栓紧固力加载工艺优化方法,在扭矩法试验基础上提出了一种基于MATLAB–GUI的螺栓拧紧加载数字化工艺技术。搭建螺栓虚拟加载平台,并以扭矩转角法加载为例,在不同润滑形式下开展了虚拟加载效果评估,两种修正策略下紧固力均有不同的改进效果,为探索螺栓连接紧固力加载工艺优化方法提供了新的途径。

To solve the problem of large dispersion of tightening force in the tightening process of aero-engine bolted connection based on the torque method,and to explore a more convenient and efficient optimization method of bolt tightening force loading process,a digital technology of bolt tightening load based on MATLAB–GUI was proposed based on torque method tests.A virtual bolt loading platform was built,and the virtual loading effect evaluation was carried out under different lubrication conditions with the torque angle method as an example.The tightening force under the two correction strategies has different improvement effects,which provides a new way to explore the optimization method of bolted connection tightening force loading process.
