某弹协调臂刚柔耦合动力学仿真

Rigid-Flex Coupling Dynamics Simulation and Analysis of a Missle Coordinating Arm

为了评估某火炮自动装填系统中弹协调臂的性能,在分析某弹协调臂的工作原理的基础上,利用Pro E建立了弹协调臂的三维模型,并在ANSYS中对模型中的弹协调臂本体部分完成网格划分和刚性区域的建立,生成弹协调臂本体部分的柔性体模态文件,在ADAMS中对柔性体施加转动约束以及液压缸驱动,对弹协调臂进行了刚柔耦合仿真,得到弹协调臂在摆动过程中的动力学特性以及动态的应力分布,给出了不满足强度要求的应力集中区域,为设计验证和后期改进提供了理论依据。

In order to assess the performance of a missle coordinating arm, it established the 3D model of the coordinator with ProE software on the basis of analyzing the working principle of a missile coordination arm, and established the rigid region and complete model meshing in the ANSYS software and got the flexible body file, and rotational constraints were imposed on the flexible body and the hydraulic cylinder drive in ADAMS, and the missle coordination arm was processed coupled simulation, and we obtained the dynamic characteristics and dynamic stress distribution of the missle coordinating arm and got the stress concentration area of which stress can not meet the strength requirements. It provides a theoretical basis for design verification and improvement later after.
