以 UR5e 一类协作臂为对象：先算出关节要多大力矩，再从零件库里选电机、谐波减速器和驱动器，做强度、疲劳、热分析和拓扑优化，编好数控程序；然后发布到问渠数字工厂，进 ERP、排 MRP、下 MES 工单，车间把它做出来。Take a UR5e-class arm. Work out the torque each joint needs, pick a motor, harmonic reducer and drive from the parts library, check strength, fatigue and heat, optimize the arm plate and write the CNC programs. Then release it to the WenQuest digital factory, where ERP, MRP and MES take it all the way to finished parts.
点任意一步，看这一步做了什么、得出什么数、产出了什么。绿色是通过，黄色是“待确认”：零件库缺数据，平台如实停下，没有估值。Click any step to see what was done, what numbers came out and what was produced. Green passed; amber is “to be confirmed”: the library lacked data, so the platform stopped instead of guessing.
↓ 发布为方案 Released as COBOT-J2 第 1 版，带自制件 RJ-201、J2-HSG 和总装工艺COBOT-J2 rev 1, with made parts RJ-201, J2-HSG and the assembly routing
演练里卡住的地方都照实记下。每一条都是学生在课上可以接着做的题目。Everything that stalled in the run is recorded as it is. Each item is a problem students can pick up in class.
零件库缺分度圆直径、孔数和孔的形式，配合检查 C3 判为“待确认”。其余 C1、C2、C4–C7、C9、C10 通过。The library lacks bolt-circle diameter, hole count and hole type, so fit check C3 is “to be confirmed”. C1, C2, C4–C7, C9 and C10 pass.
谐波减速器缺输入侧惯量，C8 无法判定。补齐样本数据后可以重算。The harmonic reducer has no input-side inertia on file, so C8 cannot be judged until the catalogue value is added.
CSF-32 缺额定寿命和额定输入转速，数字孪生算不出剩余寿命。补录规格书后即可计算。CSF-32 lacks rated life and rated input speed, so the digital twin cannot compute remaining life until the datasheet is added.
三家供应商都没有登记提前期，工厂按“交期待确认”排程，请购单需求日暂按当天。No supplier has a lead time on file; the factory schedules with “lead time to be confirmed” and dates requests today.
按连续往复运动估算，壳体最高 89.7 °C。实际工况有停顿，或者要加散热，这是偏保守的结果。With non-stop motion the housing peaks at 89.7 °C. Real duty has pauses, or needs cooling; the figure is conservative.
满载 5 kg 水平伸直为最不利工况；机械臂各节质量来自外部测量；数控程序用的是示例机床（虚构）；控制柜按 200 V 交流，真实协作臂多用 48 V 直流关节。Worst case is the arm level with 5 kg; link masses come from external measurements; CNC programs target fictional example machines; the cabinet is 200 V AC, while real cobots mostly use 48 V DC joints.
数据不够就停下来，说清缺什么，不估一个数凑结论。真实的工程就是这样做的。When data run out, stop and say what is missing; never guess a number to reach a verdict. That is how real engineering works.
每一步背后都是一门课里的一章。Every step is a chapter in one of our courses.
