以控制力矩陀螺的框架结构为研究对象,利用ANSYS有限元软件分析其结构刚度和振动模态等力学特性,得到其在大载荷作用下的应力、应变分布情况和多阶模态,并依据分析结果对框架结构进行了优化设计,以满足整个控制力矩陀螺系统的结构刚度和控制精度要求。有限元分析的结果表明通过优化设计可以使框架的结构刚度显著提高,同时使其动态特性也得到了有效改善,从而验证了在结构设计中进行工程分析的必要性和合理性,为相关的框架系统设计提供理论依据。
Taking the frame structure of moment control gyroscope as the research object, the mechanical characteristics such as structural stiffness and vibration mode were analyzed by ANSYS finite element software, and the stress and strain distribution and multi-order mode under large load were obtained. Based on the analysis Results The frame structure was optimized to meet the structural rigidity and control precision of the whole control moment gyroscope system. The results of finite element analysis show that the structural rigidity of the frame can be significantly improved by optimizing the design, and the dynamic characteristics of the frame have also been effectively improved. Thus, the necessity and rationality of engineering analysis in structural design are verified, System design provides the theoretical basis.
