针对镁合金乘用车轮毂的径向强度评估，采集数据包括产品几何参数与主要材料特性（材料屈服强度 σ_s、材料极限强度 σ_u）。在辅助车轮径向受载面沿全局坐标 x 轴方向施加 60,000 N 径向载荷，基于有限元方法开展静力学仿真，提取最大等效应力 σ_max 与最大位移，以评估产品在径向载荷作用下的结构响应与强度裕度。2. 数据处理 （1）应力比：Rs = σ_max / σ_s （2）极限应力比：Ru = σ_max / σ_u （3）安全裕度：M = 1 − Rs 3. 数据应用（参考建议） 判定顺序：不合格 → 设计偏保守 → 设计合理 → 临界状态 → 预警区间。 （1）不合格：Rs ≥ 1.0 或 Ru ≥ 0.8。说明：存在失效风险；需调整结构方案或使用更高强度材料后复评。 （2）设计偏保守：Rs ≤ 0.6 且 Ru ≤ 0.3。说明：材料利用率较低；在满足安全性与刚度前提下可开展轻量化或成本优化。 （3）设计合理：满足下列任一：a)Rs ≤ 0.6 且 0.3 < Ru ≤ Rs；b)0.6 < Rs ≤ 0.8 且 Ru ≤ 0.6。说明：材料强度发挥充分，安全与经济性平衡。 （4）临界状态：0.8 < Rs ≤ 0.9 且 Ru ≤ 0.6。说明：已接近屈服；需加强工况监测与抽检，关注长期疲劳与异常集中载荷。 （5）预警区间：满足下列任一（且未命中以上区间）a)0.6 < Rs ≤ 0.8 且 0.6 < Ru ≤ Rs；b)0.8 < Rs ≤ 0.9 且 0.6 < Ru ≤ Rs；c)0.9 < Rs < 1.0 且 Ru < 0.8。说明：强度利用度偏高或极限强度储备偏低；宜优化关键部位几何与连接，或提升材料等级，并实施更严密的质量与工况监控。

The radial strength evaluation data of magnesium alloy passenger car wheels covers the entire product lifecycle:
Upstream: Provides traceable evidence for material and supplier selection, development of enterprise/industry test specifications, and model calibration;
Midstream: Supports scheme comparison and lightweight iteration, accumulates standardized working condition and boundary condition templates, guides process planning, and realizes parameterized distribution of manufacturing quality control parameters;
Downstream: Solidifies into technical clauses for bidding and procurement, serves as the judgment basis for incoming/outgoing factory and in-service sampling inspection, and is used for third-party certification and regulatory compliance verification.
Meanwhile, this data can be used as machine learning training samples to construct a geometry-material-judgement knowledge graph, break through the digital closed-loop covering design, manufacturing, acceptance and operation & maintenance, and continuously reduce costs, shorten development cycles and improve reliability.

1. Data Collection
For the radial strength evaluation of magnesium alloy passenger car wheels, the collected data include product geometric parameters and main material properties (material yield strength σ_s, material ultimate strength σ_u). Apply a radial load of 60,000 N along the global coordinate x-axis direction on the radial load-bearing surface of the auxiliary wheel, conduct static simulation via the Finite Element Method (FEM), extract the maximum equivalent stress σ_max and maximum displacement to evaluate the structural response and strength margin of the product under radial load.

2. Data Processing
(1) Stress ratio: Rs = σ_max / σ_s
(2) Ultimate stress ratio: Ru = σ_max / σ_u
(3) Safety margin: M = 1 − Rs

3. Data Application (Reference Recommendations)
Judgment sequence: Non-conforming → Over-conservative design → Reasonable design → Critical state → Early warning interval.
(1) Non-conforming: Rs ≥ 1.0 or Ru ≥ 0.8. Note: There is a risk of failure; structural scheme adjustment or use of higher-strength materials is required for re-evaluation.
(2) Over-conservative design: Rs ≤ 0.6 and Ru ≤ 0.3. Note: The material utilization rate is low; lightweight or cost optimization can be carried out under the premise of meeting safety and stiffness requirements.
(3) Reasonable design: Satisfy any of the following conditions:
a) Rs ≤ 0.6 and 0.3 < Ru ≤ Rs;
b) 0.6 < Rs ≤ 0.8 and Ru ≤ 0.6.
Note: The material strength is fully utilized, achieving a balance between safety and economic efficiency.
(4) Critical state: 0.8 < Rs ≤ 0.9 and Ru ≤ 0.6. Note: The product is close to yielding; working condition monitoring and sampling inspection should be strengthened, and attention should be paid to long-term fatigue and abnormal concentrated loads.
(5) Early warning interval: Satisfy any of the following conditions (and do not fall into the above intervals):
a) 0.6 < Rs ≤ 0.8 and 0.6 < Ru ≤ Rs;
b) 0.8 < Rs ≤ 0.9 and 0.6 < Ru ≤ Rs;
c) 0.9 < Rs < 1.0 and Ru < 0.8.
Note: The strength utilization rate is high or the ultimate strength reserve is low; it is advisable to optimize the geometry and connection of key components, upgrade the material grade, and implement stricter quality and working condition monitoring.
