摘要

摘要: 以某兵器发射塔架摆杆系统中的水平杆为研究背景进行直梁式回转桁架结构的相关研究。首先利用刚度等效原理和质量等效原理将该桁架结构简化为绕定轴转动的连续的简单悬臂梁模型,继而通过假定模态法,数值分析等方式导出考虑结构阻尼时该结构的振动微分方程。将通过该方法所得的结果与试验结果进行了比较,结果表明运用本文的方法进行桁架结构的振动分析可取得较好的效果。

Abstract: Based on the background of rotary platform of launching tower, the continuum method based on rigidity equivalent principle and mass equivalent principle is used to simplify the truss structure into an uniform solid cantilever beam rotating around a fixed point, which makes it possible to establish the damped vibration equation with assumed mode method and numerical analysis. The agreement between the calculated results and the test results demonstrate that the proposed method of this paper is available in the vibration analysis of cantilever truss structure.
