By Solid Solutions Technical Team A typical static analysis simulation starts off by first choosing the material, selecting fixing points, applying loads and finally running our set up. However, what if we could change this type of workflow and continue with our design when some basic information is not yet known? Testing and validating your designs is always a breeze using SOLIDWORKS Simulation . Nevertheless, some designers get easily stuck when it comes to selecting materials and knowing accurate load magnitudes when simulating. Have you ever wondered what happens when you change a material in a linear static stress analysis ? Surely if we use a “softer” material like aluminium the stresses should increase drastically. This might be a shock to some of you (honestly it was to me at first), but the truth is…. nothing changes! Let’s take a look at this simple test specimen, we are simulating a tensile test by fixing one end and applying a load of 2000 N at the other. I...

American Journal of Mechanical Engineering|| Design, Fabrication and Testing of a Wet Legume Dehulling Machine By Egbe E.A.P., Roland B.O. Abstract The traditional method of dehulling legumes such as cowpea, soya beans and locust beans is by rubbing the seeds between the palms or by pounding in mortar but this process consumes time and energy. A motorized wet type legume dehuller was designed and fabricated to de-hull soaked seeds. It was designed to work on the principle of compression for the splitting of the soaked seed coat. The de-hulling is achieved by shear and friction between the beans coat and the wall of the de-hulling chamber. The device was designed and fabricated using locally available materials and technology. The motorized legume de-huller operates at effective de-hulling speed of 438 rpm and achieved a maximum efficiency of 95.2% for 6 minutes soaking period for co...

By   CAPINC   “Garbage in, gospel out.”   A slightly different take on the old adage, this is many people’s perspective on analysis results. But us engineers know better, right? Simulation results are generally only as good as the inputs to the problem. Or at least, you need to understand the limits of your engineering assumptions, and guide your interpretation of results accordingly. There are however many times you’re   certain   your results are wrong, and yet you can’t figure out why. Step One: Do Not Blame The Software It’s tempting to blame the software, but we find in tech support that less than 1% of so-called “wrong” results actually turn out to be a glitch in the system. Instead, generally the cause is PEBKAC: Problem Exists Between Keyboard And Chair.   Here are some common missteps that you can double-check before embarrassing yourself in front of a fellow engineer. Are You Using the Right Units?   SOLIDWORKS Simulat...
