SOLIDWORKS Simulation: Beam Joints

EmailFacebookLinkedInTwitterShare

SOLIDWORKS simulation allows users to take advantage of beam elements in order to simplify studies using structural members like pipes, angle iron, etc. We will begin by defining what a beam element is and then defining beam joints. Followed by showing a tip on how to create joints for structures with welding gaps. Finally, we’ll conclude by releasing degrees of freedom at the joints and observe the changes in a displacement plot. Beam definition In SOLIDWORKS Simulation there are 3 […]

Simulation Walkthrough: Trebuchet cross beam analysis

EmailFacebookLinkedInTwitterShare

Introduction: So, you’re designing a trebuchet and you need to know if the main loading cross beam is strong enough. Where would you begin? What type of study should you use? These questions and others will be answered in this blog. The main objective is to start from an unaltered CAD file and describe the process to set up an appropriate analysis. Now, I do realize that this design is incomplete. Let’s start an analysis anyway. The ability to create […]

SOLIDWORKS Flow Simulation Add-on Module Benefits – HVAC Part 2

EmailFacebookLinkedInTwitterShare

This is part 2 of a SOLIDWORKS Flow blog series. If you would like to read part 1 first, which I recommend, here is the link: SOLIDWORKS Flow Simulation Add-on Module Benefits – HVAC Part 1. The HVAC part 1 blog focused on solar absorption in transparent materials. Let’s focus on human comfort parameters for part 2. The Setup We use the same model from the part 1 blog with the addition of a simple desk and the figure of […]

SOLIDWORKS Simulation Premium: An Overview of Dynamic Damping

EmailFacebookLinkedInTwitterShare

In this blog, I will provide an overview of dynamic damping, show examples of a system under various levels of damping, and give some insight on how to define damping in a SOLIDWORKS Dynamic simulation. For those seeking a deep dive into damping, this is not that blog article. What is Damping: According to Isaac Newton, “…an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.” This “unbalanced […]

Topology: How to Use Results as a Design Guideline

EmailFacebookLinkedInTwitterShare

Topology optimization in SOLIDWORKS Simulation allows users to make lightweight, strong components. However, the resultant shape is often too complex to manufacture or contains sharp geometry. How do we take the data from Topology optimization studies and make something useful? I have designed an odd looking bracket that we can use to demonstrate a couple techniques. Fair warning, nothing you are about to see will blow you away, but you just might find a few tips to make things easier. […]

SOLIDWORKS 2019 What’s New – PLASTICS – #SW2019

EmailFacebookLinkedInTwitterShare

I’d like to begin by addressing expectation. This blog is intended to explain the enhancements made to SOLIDWORKS Plastics 2019. The actual features may contain some explanation but will not provide all the necessary explanation. For a more complete understanding of SOLIDWORKS Plastics, please consider taking one of our training courses. Our schedule can be found here: https://www.cati.com/solidworks-training/schedule/. In the past, boundary conditions could only be added to the meshed geometry of a part in SOLIDWORKS Plastics. For the 2019 […]

SOLIDWORKS 2019 What’s New – Topology Study – #SW2019

EmailFacebookLinkedInTwitterShare

SOLIDWORKS 2019 enhanced Topology studies will include new options for design constraints, export of an optimized shape, and an option to save intermediate results.         … Oh, you’re still here? Well then, lets take this opportunity to look at these enhancements in more depth. Upon browsing through the Topology studies Goals and Constraints feature you will notice 2 new sections; Frequency Constraint and Stress/Factor of Safety Constraint (see below). The Frequency Constraint allows the user to constrain the […]

SOLIDWORKS Simulation: Result Plot Tips

EmailFacebookLinkedInTwitterShare

The SOLIDWORKS simulation solved successfully! It must’ve been setup correctly or else it would’ve given an error and, even better, my max stress is below yield! Next problem, please. Pump the brakes! Neither of the statements you just read are indicators of a successful stress study. When the study solves our job, as analysts, this is just beginning. We must analyze the results plots to confirm that the stresses we see are real and not stress singularities and we must […]

SOLIDWORKS Flow Simulation: Lid creation for non-planar faces

EmailFacebookLinkedInTwitterShare

What are lids and why do we need them? SOLIDWORKS Flow Simulation supports two main study types, internal (flows bounded by outer solid surfaces, e.g. tanks, office space, etc.) and external (not bounded by outer solid surfaces, e.g. flow over a wing). Internal flow studies often contain geometry that have inlets and outlets. Flow Simulation requires that these inlets and outlets be bounded by a face. These bounded faces will then contain the info necessary to describe the flow for […]

SOLIDWORKS Simulation Case Study: Stress concentrations occurring in places they shouldn’t or too high?

EmailFacebookLinkedInTwitterShare

Finite Element Analysis (FEA) results are dependent on model, material, and boundary conditions. However, the boundary conditions have the greatest effect on the results. The boundary conditions in SOLIDWORKS Simulation must reflect the conditions in the physical experiment. A good example is the scissor lift shown below (Figure 1). As we all know, scissor lifts are designed with legs that are collapse and expand. These “legs” are pinned together. If a load is placed on the lift, then the whole structure […]
