摘要/Abstract

摘要： 螺纹连接是侵彻弹体与引信体连接的主要形式之一，针对现有动力学数值分析手段无法准确表征螺纹连接问题，提出利用薄层单元模拟螺纹连接的解决方案，并建立基于试验结果对薄层单元材料参数识别的方法。开展管螺纹模态试验研究，分析激励力幅值与螺纹松、紧连接状态对模态频率与频率响应曲线的影响，将薄层单元方法应用于管螺纹仿真计算中。结果表明：螺纹松连接状态相比紧连接状态受非线性因素的影响更大；激励力大小对螺纹松连接的测量结果影响更大；与节点固连建模方式进行比较，采用薄层单元仿真计算之后，模态频率最大误差从26.66%下降到1.35%.

Abstract: Thread connection is one of the main forms of connection between penetrating projectile and fuze body. To address the problem that thread connection can not be represented accurately by way of the existing dynamic numerical analysis, a method of simulating the thread connection using thin-layer elements is proposed, and a method for identifying the material parameters of thin-layer element based on test results is established. Modal test of pipe threads was carried out. The influences of the amplitude of excitation force and the loose and tight connection of threads on the modal frequency and frequency response curve are discussed, and the thin-layer element method is used for the simulation calculation of pipe threads. Results show that the state of loose thread connection is much more affected by non-linear factors compeared with tight connection; the magnitude of excitation force exerts greater influence on the measured result of loosely connected threads; the maximum error of modal frequency is reduced from 26.66% to 1.35% by comparing the simulated results of thin-layer element with the fixed nodes.
