Cosmsworks understand that there are many things to consider aside from static loading but I want to nail this technique down before moving on to fatigue and vibrations. This article examines what a design engineerneeds to do to perform such a test, what kind of results he or she will obtain,and explores the technology behind such simulations.
Jeffrey Rowe is an independent mechanical design and technical communications consultant.
On one hand, this version simplifies several of the analysis processes for newer users. In her easy-to-follow, friendly style, long-time Cadalyst contributing editor Lynn Allen guides you through a new feature or time-saving trick in every episode of her popular AutoCAD Video Tips.
For how long after impact should one observe or cososworks the solution? Do you use comosworks media — such as Facebook or Twitter updates, YouTube videos, or discussion forums — for work-related purposes? Or, what happensto the structure of a storage tank if the crane putting it in place should dropit?
CosmosWorks Shaft Analysis
Figures 9 and Define the analysis type and options. Specify Drop Height and Floor Orientation. I am generally very proficient in Solidworks and have little trouble figuring out how to accomplish what I need done, but this has me stumped!
All exclusively from Cadalyst! Reproduction in whole cosmosworkd in part is prohibited. Setting up a drop test study involves defining the drop height, the acceleration of gravity, and the orientation of the impact plane. With all of this capability, the program is surprisingly easy to learn and use. Can you upload a pic of the results and a pic of the failure for comparison?
All times are GMT. Problems with gross nonlinear behavior that requires a constant updateto the stiffness matrix are also more economical to solve with explicit methods. Below is a screenshot of a similar axle.
The total duration dependson how much time elapses before the object experiences all the likely impact stressit will undergo after it bounces. On the other hand,explicit techniques have the drawback of requiring very small time incrementsto provide a good, stable solution. What is mechanical cad? It creates a folder for each study, and study parameters reside in subfolders. For the user, running drop tests looks and feels just like doing any other COSMOSWorksanalysis; setting up a drop test is just like setting up any other study.
The initial release of drop test capabilities in COSMOSWorks does not supportinteractions or contact between components within an assembly after impact, orimpact between two objects.
It employs the finite element method for performing FEA finite element analysis. It’s refreshing to review a product that has no pretense of being something “entirely new and Jeffrey Rowe is an independent mechanical design and technical communications consultant. As I said before, applying any kind of restraint to the center of the shaft results in that section not bending under load, which makes sense. Analysis results can be viewed as contour plots of stress, displacement, and strains for all locations on a model, or at preselected locations such as vertices and reference points.
With offices in Colorado and Michigan, he can be reached at Define study parameters for their impact on a design. It’s refreshing to review a product that has no pretense of being something “entirely new and.
For example, a paper clip will lose its shape whenbent beyond a certain point. The default angle of the surface can be changed,and surface materials can be specified.
I think my problem occurs when I try to apply a restraint. Users can, however, evaluate the results to assess the possibility of those events occurring. To get the most out of the simulation, some questions should be addressed beforerunning the analysis:. I have tried restraining the part in several different ways but the result is either that the center cylinder section of the shaft is completely fixed inaccurate or the stresses in the part are unrealistic and do not represent the way the shaft is breaking.
The simulation needs to be run for a considerably longer time to study secondaryimpacts. Thanks ahead of time! Althoughboth approaches are equally accurate, implicit solutions of impact problems suchas dynamic drop tests take longer to solve.
Problems exporting sweep as STEP Run Analysis and Study Results To get the most out of the simulation, some questions should be addressed beforerunning the analysis: Linearproblems that have slowly varying loads with no dynamic component are more cost-effectiveor faster to solve with implicit methods.
Menus can also be used to accomplish all of this, but the tree is cksmosworks more visual and intuitive—a good thing for new users. Real-life problems generally can be solved using either approach, but dependingon cosnosworks nature of the problem, one method will be faster than the other.
The RX portfolio focuses on applicability, efficiency and scalability. Because each simulation can have tens ofthousands of time steps, it makes sense only to save the important ones ratherthan wasting computer resources on the entire series see Figure 7.
When you specify a drop height, the program automatically calculatesthe cosomsworks just before impact. Most users won’t outgrow its capabilities because the more they use it and become better acquainted with its settings and how to interpret its results, the more they discover what it can do.
Discrete element method simulation software enhances particle collision analysis, spring and damper motion, fiber modeling Does altering the tolerances of restraints in the correct manner allow for this type of result?
