Introduction
In mechanical engineering, risk management is a matter of physical integrity. Whether designing an industrial turbine, a medical implant, or an automotive chassis, engineers must account for forces that are often invisible until a failure occurs: stress, fatigue, thermal expansion, and vibration.
Risk & Safety Analysis for Mechanical Engineering within a PLM context involves identifying potential physical failures before they happen. It is the process of evaluating how mechanical components will behave under extreme conditions and ensuring that “Safety Factors” are built into the design intent. By integrating this analysis into the Product Lifecycle Management (PLM) process, companies ensure that safety isn’t just an afterthought of the CAD model, but a core requirement that drives the entire development cycle.
Key Categories of Mechanical Risks
A comprehensive mechanical safety analysis must address several physical dimensions:
1. Structural and Material Risks
Risks related to material fatigue, corrosion, or exceeding the yield strength of a component.
- Analysis: Finite Element Analysis (FEA) results integrated with risk logs to identify “high-stress” zones.
2. Kinetic and Moving Parts Risks
Risks involving entanglement, crushing, or high-speed collisions in machinery.
- Analysis: Evaluation of guards, emergency stops, and clearance requirements.
3. Thermal and Pressure Risks
Risks associated with overheating, combustion, or the rupture of pressurized vessels.
- Analysis: Thermal mapping and pressure-relief system validation.
4. Human-Machine Interaction (HMI)
Risks arising from the physical ergonomics of the product. Is it too heavy to lift? Does it vibrate at a frequency that causes long-term injury?
Core Methodologies: FMEA and ISO 12100
In the mechanical world, two frameworks are dominant:
- Failure Mode and Effects Analysis (FMEA): Breaking the mechanical assembly into components and asking, “How can this bolt/gear/seal fail, and what happens if it does?”
- ISO 12100 (Safety of Machinery): A systematic approach to risk assessment and risk reduction, focusing on the design phase to eliminate hazards rather than just warning against them.
The Integration Challenge: From CAD to Risk Matrix
A major “pain point” in mechanical engineering is the gap between the CAD/CAE tools (where the physical reality is simulated) and the Risk Management tools (where the hazards are documented).
- The Problem: If a simulation shows a part will fail under a certain load, that information often stays in the engineering department and isn’t reflected in the official risk-compliance report.
- The Solution: A Digital Thread that connects simulation results directly to risk mitigation requirements.
How Visure Solutions Enhances Mechanical Safety Analysis
Visure Requirements ALM Platform provides the structure needed to manage the heavy-duty risks of mechanical engineering:
- Risk-Linked Requirements: Visure allows engineers to link a specific mechanical risk (e.g., “Frame Failure under 5-ton load”) directly to the requirement that mitigates it (e.g., “Use High-Grade Carbon Steel with Safety Factor 2.0”).
- Integration with Simulation Data: By capturing the “pass/fail” results of FEA and other mechanical simulations, Visure provides real-time updates on the safety status of the design.
- Safety Factor Management: Visure can manage the technical parameters and safety factors required by standards, ensuring that any deviation triggers an immediate review.
- Compliance with Machinery Directives: Visure helps document the “Technical File” required by the EU Machinery Directive or OSHA standards, ensuring that all physical hazards have been identified and mitigated.
- Impact Analysis for Material Changes: If a supplier changes a material grade, Visure’s traceability allows you to see instantly which mechanical risks are affected by that change.
Conclusion
Mechanical safety is the foundation of consumer trust and industrial reliability. In the high-stakes world of mechanical engineering, there is no room for “unknown unknowns.” A robust Risk & Safety Analysis integrated into the PLM lifecycle turns potential catastrophes into manageable engineering challenges.
By using Visure to anchor your mechanical risk data, you ensure that every physical hazard is addressed by a verified design requirement. This closed-loop approach doesn’t just prevent accidents; it creates a more efficient engineering process where safety and innovation go hand-in-hand, resulting in products that are as resilient as they are advanced.
