When you plan the design of a new product, one of the critical steps is structural analysis. It concerns the product’s ability to withstand loads and stress without failing. It is vital because it guarantees the safety, functionality and durability of the product. Let’s explore how this analysis is carried out efficiently.
The structural analysis process in product design
Before getting to modelling and simulation, the first step in structural analysis is to understand the design specifications and requirements. This means knowing what functions the product must perform and under what conditions it will operate. Determine the materials, their geometry and any other relevant factor. Keep in mind that an over-engineered design can be expensive, but a deficient design can be dangerous.
What tools do I use for structural analysis?
In this technological era, structural analysis benefits from software as well as manual methods. Among the most popular are programs such as ANSYS, SolidWorks and Abaqus. These allow finite element simulations, which divide a design into small parts called elements and calculate how each one withstands various loads.
Pros:
- Accuracy of results.
- Ability to run multiple simulations in less time.
- Cost reduction by minimising errors in the prototype phase.
Cons:
- Requires advanced technical knowledge.
- Can be expensive depending on the licence.
What aspects should I consider during the analysis?
There are several factors that cannot be overlooked during structural analysis. The choice of material is one of the cornerstones affecting the overall strength of the design. For example, if we are designing a mechanical part, deciding between steel and aluminium may come down to both strength and weight.
Besides materials, there are external and internal forces to consider. External forces can be weight or other applied loads. Internal ones, such as those arising from motion, are also vital. Determining the right safety factor, which is the margin of error in the calculated forces, helps prevent structural failure.
Spanish regulations and structural analysis
In Spain, structural analysis must align with standards set by building regulations, such as the Código Técnico de la Edificación (CTE). This code addresses structural safety requirements and applies to different types of projects. Referring to these standards during design ensures compliance with current regulations and avoids later legal problems.
Lessons learned from success stories
Over the years, success stories in structural analysis have provided valuable lessons. A notable example is the automotive sector, where aerodynamics and strength are key. Well-known brands such as Tesla have used advanced tools to optimise the structure of their vehicles. The result: safer, more efficient cars. Applying these lessons to other sectors can make a significant difference.
Finally, technological evolution and the growing demand for safer, more efficient products make structural analysis an indispensable component of the design process. Taking it seriously not only guarantees a quality product, it also protects users and strengthens the company’s reputation.
