A Licensed Mechanical Engineer at Glew Engineering Consulting was asked by a company in Southern California to provide a Professional Engineer (P.E.) review of body modifications that they made to a theme park owned 1983 Sport Utility Vehicle (SUV) that they had converted to an electric vehicle. Figure 1. A Mechanical Engineer Analyzed the Front of Custom Sport Utility Vehicle Licensed Mechanical Engineer Reviews a Modified Electric Vehicle The client had already designed and built a vehicle, so Glew Engineering analyzed an “as built” vehicle. The company hoped to repurpose a float/SUV that they had used previously in parades. Our client was requested by the theme park to repurpose the SUV, and perform cosmetic alterations [...]
The entertainment industry relies on "entertainment engineers," e.g. mechanical engineers, electrical engineers, and others for standards https://www.smpte.org. Perhaps more importantly, the movie industry requires Licensed Mechanical Engineers to safely innovate and amaze. Film sets are complex physical productions, most of which are not digital special effects. The film industry utilizes Licensed Mechanical Engineers to create complex props and various special effects that move, exploded, burn, and fly. The mechanical engineers specializes in designing and making a wide range of mechanical devices that fulfill a specific purpose for the film or set they are engaged, or modify available technology to quickly achieve stupendous results. Licensed Mechanical Engineers also help in structural aspects of heaving rigging, such as lighting (See above Fig. 1 [...]

Licensed Mechanical Engineers Help You Ditch Suburbia Licensed Mechanical Engineers Ensure Vehicle Safety and Comfort The recreational vehicle industry (Fig. 1) is flourishing. People can use their RVs full time part, part time or travel the country for months at a time. A Licensed Mechanical Engineer (Licensed Mechanical Engineers Role in Manufacturing) makes certain that travel is safe and comfortable at the same time, without missing out on the comforts of home and your favorite kitchen. (Fig. 2) Recreational vehicles' kitchens are designed with adequate ventilation to ensure that no fires occur. Across that spectrum, the RV industry is enjoying an unprecedented growth. Who are these RVers? They love the beauty and solace of being outdoors, abiding [...]
Mechanical Engineering Consultants Use 3D CAD Software Comparison via Custom Motorcycle Frame: Creo vs Solidworks vs Inventor: Part 2Glew Engineering 2018-03-08T12:14:53+00:00
3D CAD Software Comparison Blog Series: Starting the Motorcycle Frame Design in Solidworks™ Welcome back to our 3D CAD software comparison blog series. Recall that in last week’s discussion, as Mechanical Engineering Consultants we introduced our plan to to model a motorcycle frame in three different 3D CAD software packages. We gave a brief history of the three CAD software packages that Glew Engineering employs: Solidworks™, Creo™, and Inventor™. In this week’s blog, as Mechanical Engineering Consultants we use Solidworks™ CAD software to model a portion of the motorcycle frame, a simple tube, while comparing three modeling techniques: Extruding Sweeping Weldment Motorcycle Frames We designed a simple bobber inspired motorcycle frame, this is conceptual, yet realistic enough to illustrate [...]
Fig. 1 A street bike shown in CAD mesh. Mechanical Engineering Consulting Group Evaluates 3D CAD Programs Mechanical Engineering Consulting Testing of Creo™, Solidworks™, and Inventor™ Mechanical Engineering Consulting service companies largely use one of three 3D CAD programs: Creo™, Solidworks™, and Inventor™. At Glew Engineering, we have licensed seats of all three CAD mechanical design packages. We reviewed the CAD workflow and feature sets of each 3D CAD program using motorcycle frame design as an example. Also, we showed that some of the specialized commands of each 3D CAD software programs are better suited for specific tasks. Our engineers are experienced with 3D CAD, stress analysis by Finite Element Analysis (FEA), as well as Computational Fluid Dynamics (CFD) FEA [...]
Italian Masters: Volta Jump-Starts Electrical EngineeringFigure 1: Girolamo Cardano (1501-1576) Welcome back to our series on Italian Masters of math and science. Last week I wrote about Galileo’s extensive accomplishments both in the field of astronomy and beyond. This week, I’ll take a look at another renaissance polymath who dabbled in astronomy, along with his work in mathematics, medicine, biology, chemistry, philosophy, and gambling (yes, seriously): Girolamo Cardano. Cardano is a less well-known figure than Galileo or some of the other scientists I’ve written about who have famous equations or units of measurement named after them, like Volta or Torricelli. He is regarded as one of the greatest mathematicians of his age, however, and made a great many contributions to science, [...]

Figure 1: Mars Exploration Rover By NASA/JPL/Cornell University, Maas Digital LLC [Public domain], via Wikimedia Commons Depending on which Facebook pages or Twitter feeds you follow, some of you may have caught wind that Opportunity (Mars Exploration Rover B, Figure 1) recently passed its twelfth anniversary of its landing on the red planet. Opportunity’s ongoing trek across Mars represents a fantastic accomplishment in engineering. At the time I’m writing this, the rover has been in continual operation for over 4,300 Earth days (that’s about 4,185 Sols, or Martian days). Considering its original planned mission time of 92 Earth days, Opportunity has exceeded its design lifetime by 4,700%. Imagine having a car that, instead of a [...]
We'll continue on now with our blog series on finite element analysis (FEA). After discussing how to best set up a computer-aided design (CAD) model for FEA simulation, in this blog I'll cover the next step: meshing the model and applying boundary conditions. "Meshing" is the process by which the CAD model is separated into discrete finite elements; it can be done in the same program that runs the FEA numerical simulation later, or it might be performed in a standalone program, depending on your software. Boundary conditions are the loads (forces, movements, impacts, etc) and constraints that interact to actually cause deformation and stress in each element, and in turn the model as a whole. Mesh Generation The mesh essentially [...]
Figure 1: Reinforced concrete mesh © Glew Engineering Consulting Welcome back to our blog series on FEA. In the last blog entry, we introduced some of the fundamental concepts in finite element analysis (FEA). This entry in the blog series focuses on the initial steps in preparing a computer-aided design (CAD) model ready for use in an FEA program. Since FEA programs are very sensitive to the data they have to work with, it's important that the CAD models being analyzed are compatible with the analysis methods the FEA program uses. In order to illustrate my points throughout the blog series, I will introduce a recent FEA consulting project that we completed. Modeling Punching Shear in a Concrete Slab We were recently approached by an academic, who was examining [...]
Figure 1: FEA mesh and shear stress results for a reinforced concrete slab © Glew Engineering Consulting, 2016 Finite Element Analysis Consulting (FEA) In this series of blogs on FEA, we will first cover some basic elements common to many FEA projects, and then in subsequent blogs in this series, illustrate those methods through examples. One of the services that Glew Engineering Consulting provides is finite element analysis consulting (FEA). FEA consulting has been a great boon to the engineering profession, allowing mechanical engineers and civil engineers to accurately model the stress and strain behavior of complicated parts and assemblies prior to building physical prototypes. FEA programs are capable of predicting the effects of loads and impacts, variations in temperature, changes in pressure, and [...]
