摘要: 齿轮传动是航空、风电、新能源等领域中广泛应用且不可替代的核心部件,其设计过程涉及材料、摩擦、几何等多学科耦合分析和多约束优化决策。以大语言模型(Large language models, LLM)为代表的人工智能(Artificial intelligence, AI)正在驱动新一轮科技变革,广泛应用于生物医疗与新材料等领域。然而,由于齿轮传动对设计规范和稳健性要求极高,LLM在该领域尚无成熟应用。基于大语言模型和多智能体协同的齿轮传动智能设计方法,采用分层分布式多智能体架构(Hierarchical multi-agent system, HMAS)结合状态有向图和ReAct推理行为方法,实现对复杂齿轮传动设计任务的全流程控制与参数交互,显著提升输出可靠性和可解释性。该方法可实现需求分析、构型推荐、任务推理规划、元件计算校核、系统集成设计、多目标优化、报告生成、CAD生成等全流程设计任务的自主完成,实现涵盖齿轮、轴承、轴等零部件材料、工艺、结构设计与性能评估等800余项参数的整体方案设计周期缩短至10 min以内。通过航空、风电、新能源汽车等领域中多种复杂构型齿轮传动系统案例测试与评估,本文方法设计性能和鲁棒性优于人工设计,且有效改善了目前大模型普遍存在的参数计算不准、设计依据性与探索性不足等问题,综合能力比主流大模型提升23.91%~53.60%,为AI赋能工业设计树立了新范例。

Abstract: Gear transmission is a fundamental component in industries such as aerospace, wind power, and new energy. Its design process requires multidisciplinary coupled analyses and multi-constraint optimization involving materials, friction, geometry, and other factors. Artificial intelligence (AI), particularly large language models (LLMs), is driving a new wave of technological innovation and has been broadly applied in domains such as biomedicine and advanced materials. However, due to the stringent demands for specification adherence and robustness, mature LLM applications in gear transmission design remain undeveloped. This study introduces an intelligent gear transmission design methodology leveraging LLMs and collaborative multi-agent systems, employing a hierarchical multi-agent system (HMAS) architecture integrated with state-oriented graphs and ReAct reasoning methods. This approach enables comprehensive process management and parameter coordination in complex gear transmission design workflows, significantly enhancing output reliability and interpretability. The proposed methodology autonomously executes the entire design workflow—including requirements analysis, configuration recommendation, task reasoning and planning, component calculation and verification, system integration, multi-objective optimization, report generation, and CAD modeling—completing the overall scheme design, which involves over 800 parameters related to component materials, processes, structural design, and performance evaluation, in less than 10 minutes. Evaluation using various complex gear transmission cases in aerospace, wind power, and new energy vehicles demonstrates that the proposed method outperforms traditional manual design in terms of both performance and robustness. Additionally, it effectively resolves prevalent issues observed in mainstream LLMs, such as inaccurate parameter calculations and insufficient innovation and justification in design. Overall, the capability of this approach exceeds that of leading LLMs by 23.91% to 53.60%, establishing a new paradigm for AI-driven industrial design.
