A day without using plastic parts is unimaginable. From consumer electronics to children’s toys, kitchen gadgets and medical devices, the use of components made from plastic materials has steadily increased. The majority of these plastics parts are produced through injection molding, the process of injecting liquefied plastic materials into a mold, cooling or solidification of the material and ejection of the molded part.  

Building assemblies and getting them to move is one of the most satisfying aspects of designing in a CAD environment. After designing all those parts we can assemble them and start to see just how they will act and react before the first part is ever manufactured. Analysis of movement gives us insights we otherwise would not have access to without producing a part or prototype. Are parts colliding? Do they fit together as intended? Can it be assembled and does its assembly require special tools? How much space near our machine is required for it to perform its task? The list of questions goes on. In this blog article, we will go over how to use tools within SOLIDWORKS to virtually test robotic movement without any physical mock-ups.

You’re working away in SOLIDWORKS Flow Simulation when you run into this message, “Fluid volume recognition has failed because the model currently is not watertight.” Ugh. It can really put a cramp in your workflow. Even the tiniest holes keep SOLIDWORKS Flow Simulation from detecting your fluid region making it impossible to run a study. Luckily, you don’t have to scrap your work and start over. Since SOLIDWORKS 2013, there’s a tool that makes it extremely easy to locate these frustrating gaps and holes in internal studies. It’s called Leak Tracking and it shows you exactly where the problem areas are so you can finish setting up your model for an internal flow study.

The Hyatt Regency Walkway collapse was an event that changed engineering forever. This example serves as a lesson to many about double-checking your work. We should always use every tool available to us to make sure our designs are safe and that they perform how we expect. I wonder what the engineers on this project could’ve done if they had a simple tool to use that could have raised a red flag after just a few minutes of set up.

SOLIDWORKS Simulation is one of the leading design analysis tools that brings the power of simulation into the SOLIDWORKS 3D CAD environment, to conduct design validation early in the design process. Ease of use and tight integration within CAD enables designers and engineers to run different types of simulation from linear static to nonlinear static to dynamic analyses. However, even with its extensive capabilities, there are situations where SOLIDWORKS Simulation needs a little extra help. In this blog post, we’ll take a look at one of these situations, running a snap fit analysis and will walk through assisting SOLIDWORKS Simulation with Simulia Structural Simulation Engineer (SSE).

In any simulation project, setting up the correct boundary condition and interpreting the results are the most challenging phases, regardless of the simulation software being used. Certain tools and display settings available within SOLIDWORKS Simulation result plots can help you during the simulation result interpretation process. The stress hot spot diagnostic tool, available for linear static studies using solid and shell elements, can be used to detect regions of the model where stress singularities exist, for example, sharp edges or corners or the location of fixtures.

It is important to design products that are strong yet light in weight while resisting damage against impact or unanticipated shocks and vibration. The static analysis assumes that loads are constant or applied very slowly, ignoring the effects of inertial and damping forces. For many practical cases, loads are not applied slowly. In fact, they change with time or frequency. To simulate such conditions, a dynamic analysis is required.

At TriMech, our engineers are always excited about the technologies that we offer our clients. From the latest in CAD changes to the newest advancements in additive manufacturing, our goal is to have the best technical staff available. One of the ways that we encourage their advancement is by embracing the use of technologies for personal experiences and professional development.

During this multi-part video series, we are going to highlight one of our Senior Application Engineers, Ryan Zeck. Ryan has been racing since before he was nine years old and has always had a passion for going fast! So for this project we’ve given Ryan access to TriMech’s entire product portfolio to see how we can make his car, a Thunder Roadster, go even faster.
