The Impact of Finite Element Analysis on Medical Device Design
Finite Element Analysis in Medical Device Design: Benefits, Challenges, and FDA Guidance Published online: 6 June 2018 © Taiwanese Society of Biomedical Engineering Medical device design has advanced rapidly in recent years, thanks in part to the integration of finite element analysis (FEA) into product development. This computational method allows engineers to test, […]
Custom Load Sensor Design-Proof of Concept Model
Reinventing the Load Sensor: Innovation on a Budget Foil strain gauges had their time. But development doesn’t always need high-priced lab gear. Sometimes, hardware-store parts and creativity are enough. The Problem: A Pricey Sensor Market A customer asked me to design a load sensor for a trailer hitch. Since the application could scale to […]
Design, Analysis, Testing, and Manufacturing
A System-Wide Approach to Engineering Success Why Integration Matters Design, analysis, testing, and manufacturing can’t exist in silos. To move forward effectively, these disciplines need to align and work as a single system. A system-wide approach ensures that engineering tasks are viewed from every angle, producing stronger, more reliable results. I bring experience across all […]
Computerized Wind Tunnel – A Successful Test
. Smarter Prototyping: How CFD and 3D Printing Are Changing Engineering From Sketch to Prototype in Days Modern engineering tools have transformed the way we develop products. What once required weeks of machining and lab testing can now be achieved in days. With hand sketches, 3D CAD, CFD simulations, and 3D printing, engineers can quickly […]
Combining Test Data and Analysis
A small amount of test data can go a long way to reducing the analysis effort. And it can be easy and inexpensive to acquire. For example, this could be the temperature of electronic components within a circuit card, or wind loads on a structure. The methods by which electronic component manufacturers provide heat dissipation data can vary widely. These can […]
Classic Methods or FEA – Which is Better?
The Hidden Value of Classical Analysis in an FEA World FEA vs. Classical Analysis: Which is better? The short answer? It depends. FEA can do everything classical analysis can, but not the other way around. Still, I often use classical analysis to back up FEA results. It takes more time, but it builds confidence. The […]
Product Development Using Finite Element Analysis (FEA)
Simulation-Driven Product Development Design Models as the Starting Point In modern engineering, design models are the foundation of simulation-driven product development. These models may be detailed 3D CAD representations or simplified geometries that preserve key features for finite element analysis (FEA). Using the same geometry from design to manufacturing reduces translation errors and improves accuracy. […]
Electronics Thermal Analysis part 1
This series of articles explores thermal and stress analysis for electronic assemblies — no matter where they are used: cell phones, cameras, computers, avionics, missile and defense systems, or high-power applications. Electronics face demanding environments. A few of the key analyses and tests they must tolerate include: 🔥 Temperature 💥 Shock 📳 Vibration 🌡️ […]
Electronics Thermal Analysis: Part 2
A look at a electronic component data sheet and setting up a FEA analysis This particular component is very simple-nothing more than a single transistor-but the analysis techniques are very similar for all. The information we are after are the thermal characteristics shown in figure 2. Figure 1 – general information for a transistor Figure […]
