Introduction
In the traditional engineering workflow, “seeing the product for the first time” required building a physical prototype—a process that was slow, expensive, and often revealed errors too late. Digital Mock-Up (DMU) changes this paradigm by creating a full-scale, high-fidelity virtual representation of the product.
A DMU is much more than a 3D image; it is an integrated environment where all components (mechanical, electronic, and software) come together to simulate the physical product. In a Product Lifecycle Management (PLM) strategy, the DMU acts as the “master assembly,” allowing teams to investigate how thousands of parts interact before a single piece of material is cut.
The Core Functions of a Digital Mock-Up
DMU technology provides specific tools to validate the product architecture during the design phase:
1. Spatial Integration & Clash Detection
Automatically identifies if two parts are occupying the same space or if there is insufficient clearance for moving parts.
- Benefit: Prevents assembly failures on the factory floor.
2. Kinematic Analysis
Simulates the motion of mechanisms (gears, hinges, robotic arms) to ensure the product functions as intended throughout its range of motion.
3. Human Factor & Ergonomics
Virtual “mannequins” are placed in the DMU to test if a person can comfortably reach controls or if a technician has enough space to perform maintenance.
4. Technical Documentation
Using the DMU to generate assembly instructions, exploded views for manuals, and marketing visuals directly from the engineering data.
DMU as the Heart of the Digital Thread
The Digital Mock-Up is the primary interface for cross-functional collaboration. It allows:
- Procurement: To see exactly what parts they are buying.
- Manufacturing: To plan the assembly sequence.
- Service: To simulate repair procedures years before the product is in the field.
Strategic Advantages of DMU in PLM
| Advantage | Business Impact |
| Zero Physical Prototypes | Savings of millions in materials, logistics, and labor. |
| Early Error Detection | Resolving 99% of design flaws in the virtual stage. |
| Massive Scale | Ability to manage products with millions of parts (e.g., a cruise ship or a commercial jet). |
| Parallel Engineering | Multiple teams can work on different sections of the DMU simultaneously. |
How Visure Solutions Powers the DMU Environment
While DMU tools handle the 3D visualization, Visure Requirements ALM Platform manages the Functional Validation of that virtual prototype:
- Requirement-to-Component Mapping: Visure ensures that every part in the DMU exists for a reason. If a part doesn’t link back to a requirement, it’s unnecessary weight and cost.
- Visual Validation of Compliance: When a DMU analysis (like a crash simulation or ergonomic test) is performed, Visure stores the result as “Evidence of Verification,” linking the 3D result to the regulatory standard.
- Change Orchestration: If a clash is detected in the DMU, Visure manages the change request process, ensuring that the redesign doesn’t violate other functional requirements.
- Multi-Domain Synchronization: Visure bridges the gap between the 3D DMU (Mechanical) and the software/logic requirements, ensuring that the virtual prototype behaves exactly like the final smart product.
Conclusion: The Ultimate Single Source of Truth
The Digital Mock-Up (DMU) is the culmination of the digital engineering journey. It is where the abstract becomes visible and where complex systems are tamed through visualization and analysis.
By integrating DMU capabilities with a robust requirements management platform like Visure, organizations don’t just build a “pretty model”—they build a Certified Virtual Prototype. This synergy ensures that when the product finally moves from the digital world to the physical one, it does so with zero surprises, maximum quality, and the lowest possible cost.
