摘要

针对某自行火炮自动装填系统中的开式链传动输弹机，为了掌握其工作过程中的动力学特性和关键构件的受力情况，利用RecurDyn软件建立了输弹机多刚体动力学模型并进行仿真，利用实验数据校核所建模型的合理性，得到了输弹行程中链条的动力学特性；之后基于多柔体动力学（MFBD，Multi-Flexible-Body Dynamics）技术完成对关键构件的柔性化，建立了输弹机刚柔耦合动力学模型，得出了不同位置构件在输弹行程中的应力云图，通过分析确定了危险点的位置，分析结果对输弹机的故障机理、故障演化规律及疲劳性能研究等提供了依据。

Abstract

In order to master the dynamic characteristics and key component force condition of ramming mechanism of automatic loading system of a certain artillery, the multi-rigid-body dynamics model was established in RecurDyn, then dynamic characteristics in ramming process of ramming mechanism were obtained while the experimental data were used to check and ensure its credibility. Based on MFBD (Multi-Flexible-Body Dynamics), the rigid-flexible coupled simulation model was completed after establishment of flexible component, the force of key component in ramming process was obtained to determine the dangerous location, the basis of the failure mechanisms, fault evolution and fatigue property of ramming mechanism was provided with the analysis results.
