摘要
为了提高飞机线束在机上装配的可靠性,确保用电设备之间正常的互联作用,设计一种检验线束装配牢固的拉力计算方法.通过3个正交方向上的随机振动试验获取线束的响应加速度特征,结合线束在振动过程中的受力模型提出一种基于加速度方均根值的拉力计算方法,并利用搭建的线束拉脱力试验平台,验证了该方法的可行性.
Abstract
In order to improve the reliability of aircraft harness assembly and ensure the normal interconnection between electrical equipment,a force calculation method for inspection harness assembly inspection is designed.The response acceleration characteristics of wire harness are obtained through random vibration tests in three orthogonal directions,and in combination with the force model of wire harness in the vibration process,a force calculation method based on the root mean square value of acceleration is proposed,and its feasibility is verified by the constructed wire harness pull off force test platform.
