Heavy Equipment Design / Reverse Engineering重型装备设计 / 逆向工程
Customised, non-standard design of large ball mills大型球磨机非标定制化设计
This project involved the redesign of the main bearing system for a large ball mill. Based on existing technical documentation and on-site measurement results, the project completed the reconstruction of a three-dimensional model, carried out structural optimisation, and produced a complete set of production drawings.该项目针对大型球磨机主轴承系统开展重建设计。项目基于已有技术资料及现场测量结果，完成三维模型重建、结构优化，并输出完整生产图纸。
Based on the client’s requirements and the actual on-site conditions, a complete set of 3D models was designed using SOLIDWORKS.根据客户需求及现场实际情况，利用SOLIDWORKS设计整套3D模型
Close-range evidence records the geometry and condition that could not be resolved from the legacy drawing set alone.近距离现场证据记录了仅凭历史图纸无法确认的几何关系与设备状态。
Context and constraint背景与约束
Legacy documentation required engineering interpretation and validation against existing equipment interfaces and field measurements.历史技术资料需要结合现有设备接口与现场测量结果进行工程解读和验证。
Engineering decisions工程决策
