基于数字孪生的新能源张力机关键部件的优化OA

The new energy tension machine needs to meet requirements such as compact structure and dynamic performance.The reel,as the main load-bearing component,experiences complex forces during operation and requires high strength and lightweight design.Its installation and use also affect the structural rigidity of the equipment during operation,so structural optimization de-sign of the reel is key to the research and development of the new energy tension machine.To meet the technical needs for light-weight design and collaborative optimization of dynamic performance in the new energy tension machine,a design method for key components that integrates digital twins and topological optimization is proposed.This involves real-time mapping of the stress/strain field and instability critical load of the reel under extreme working conditions using a twin body;with the goals of maximi-zing structural stiffness and minimizing mass,the layout of the weight-reduction holes in the web and the configuration of the inner cylinder reinforcements are iteratively optimized in digital space;and a lightweight design scheme is generated in conjunction with additive manufacturing constraints.Experiments show that the optimized reel achieves a weight reduction of 22.3％,the buckling critical load increases by 15.64％,and the dynamic response characteristics are significantly improved.This method overcomes the limitations of traditional empirical design and can provide theoretical support and engineering references for the digital collab-orative optimization of high-end equipment.
