摘要
根据放大器下装光机模块的接口尺寸分析了应用于特定环境下的升降平台的结构设计要求,采用等强度悬臂梁理论构建了升降平台的力学计算模型,推导了变截面平台结构的刚度公式并以此计算了升降平台的主要结构参数。运用ANSYS软件构建了升降平台的三维模型并开展了结构力学分析,分析结果验证了理论设计参数的合理性。在提高安全系数的前提下运用ANSYS软件重构了平台三维模型并进行了平台刚度冗余情况分析。以平台质量最轻为主要目标,采用ANSYS软件的全域寻优工具对升降平台的结构参数进行了优化,并将优化结果应用于某系统的垂直举升机构样件制作。
Abstract
The structure design demands of lift platform used in certain environment are studied based on the interface dimension of the bottom load optomechanical module of amplifier. The calculation model of the lift platform is designed based on the equal strength beam theory. The stiffness formula of variable cross-section platform structure is deduced, and the main structural parameters of the lift platform are calculated based on this stiffness formula. The 3D model of the lift platform is built based on ANSYS software and the structural mechanics analysis of the lift platform is carried out, then the rationality of the theoretical design parameters is verified by the analysis results. On the premise of improving the safety factor, the 3D model of the platform is reconstructed with ANSYS software and the stiffness redundancy analysis of the platform is carried out. For the sake of getting the lightest quality of the lift platform, the main structural parameters of the lift platform are optimized by using the global optimization tool of the ANSYS software. The optimization results are applied to the production of a vertical lifting mechanism sample of a system.
