摘　　要：传统飞机部件交点装配数字化协调方法直接对交点轴线进行降维,未对交点轴线公差域进行建模,造成装配精度低、协调效果较差,为此提出基于混合容差约束的飞机部件交点装配数字化协调方法。对交点轴线公差域进行建模,基于混合容差约束进行交点轴线降维,以实现更精确的控制和检测,设计部件交点装配协调流程,实现基于混合容差约束的飞机部件交点装配数字化协调。实验结果表明,该研究方法显著提高了装配精度,具有较好的协调效果。The traditional digital coordination method of aircraft component intersection assembly directly reduces the dimensionality of intersection axes without modelling the tolerance domain of intersection axes,which results in low assembly accuracy and poor coordination effect,so the digital coordination method of aircraft component intersection assembly based on hybrid tolerance constraints is proposed.The intersection axis tolerance domain is modelled,the intersection axis is downgraded based on hybrid tolerance constraints to achieve more accurate control and detection,and the intersection assembly coordination process is designed to achieve the digital coordination of aircraft component intersection assembly based on hybrid tolerance constraints.Comparative experimental results show that the research method significantly improves the assembly accuracy and has a better coordination effect.
