Structural Strength Challenge: Heavy-Duty Load-Bearing Solution with SPCC

A 2.0mm SPCC steel sheet supports 800kg of precision instruments using a "box-in-box" double-layer structure (with polyurethane shock absorption filling the gap), increasing bending stiffness by 90%. The bending process employs a springback compensation algorithm (angle compensation of 2-3°) to ensure joint tolerances of ±0.5mm. The heavy-duty cabinet base incorporates 6mm reinforcing ribs, with a 20% weight reduction achieved through ANSYS topology optimization.
