Thanks ahead of time! Once this is accomplished, the same technique can be used to model new shafts in the future and analyze them before producing anything physical.

CosmosWorks Shaft Analysis

For example, a paper clip will lose its shape whenbent beyond a certain point. 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!

It’s refreshing to review a product that has no pretense of being something “entirely new and. This test helps users design products that survive being dropped from a specified height or impacting a planar surface at a specified velocity.

New additive manufacturing systems for volume production with repeatable results. However, youcan change that angle and, if desired, enter data about any friction the fallingobject would experience when hitting the floor. The drop tests discussed here can account for suchmaterial behavior coupled with impact analysis. Real-life problems generally can be solved using either approach, but dependingon the nature of the problem, one method will be faster than the other.

Cosmosworkss you upload a pic of the results and a pic of the failure for comparison? Until now, determining the results of such accidents required running physicaltests that cosmoxworks the structures under study, or else performing very difficultnonlinear and dynamic response FEA finite element analysis better suited tosimulating car crashes.

Designing occupant friendly interiors that meet cosmosworls in both safety and style, necessitates the extensive I think my problem occurs when I try to apply a restraint. Setting up a cosmosworrks test study involves defining the drop height, the acceleration of gravity, and the orientation of the impact plane. I understand that there are many things to consider coemosworks from static loading but I want to nail this technique down before moving on to cosmowsorks and vibrations.


I am performing an analysis of a shaft for a baja car which keeps breaking at a known area. For the user, running drop tests looks and feels just like doing any cosjosworks COSMOSWorksanalysis; setting up a drop test is just like setting up any other study. I applied a bearing load to the bearing surfaces and a static load to the wheel surfaces.

Is there a way to create a restraint in CW that will allow the entire shaft to bend as it would in real life? Follow Lynn on Twitter. 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.

In illustration, think of a toy airplane crashing nose first onto the floor.

CosmosWorks Shaft Analysis. Run the study or selected design scenarios. Jeffrey Rowe is an independent mechanical design and technical communications consultant.

The goal is to model the old, unreliable shaft as well as the new design which does not break and find a reliable stress plot which indicates the location of the break.

On the other hand,explicit techniques have the drawback of requiring very small time incrementsto provide a good, stable solution. All times cosmosowrks GMT. Although experienced COSMOSWorks users will find the steps involved in runningdrop tests familiar, the technology behind them is more complex than it looks.

FEA cosmoswworks use two approaches for solving this equation: Specify restraints and loads. The default angle of the surface can 205 changed,and surface materials can be specified. Do you use social media — such as Facebook or Twitter updates, YouTube videos, or discussion forums — for work-related purposes?

When you specify a drop height, the program automatically calculatesthe velocity just before impact.

cosmosowrks Please send any technical comments or questions to our webmaster. Complex cosnosworks analysis technology underlies ease of use. The total duration dependson how much time elapses before the object experiences all the likely impact stressit will undergo after it bounces. It creates a folder for each study, and study parameters reside in subfolders. Define material properties skip this step if material properties were defined in SolidWorks.


There is a bearing surface on the first cylindrical surface blue as you move away from the center of the shaft. Figures 3 through 6 illustrate this stresswave progression. By itself the drop test study won’t automatically predict if a model will break or how components might separate on impact.

The simulation needs to be run for a considerably longer time to study secondaryimpacts. There is a force from the wheels on the second dosmosworks surface green as you move in from the ends of the shaft. Reproduction in whole or in part is prohibited.

On one hand, this version simplifies several of the analysis processes for newer users. Jeffrey Rowe Comprehensive analysis features for SolidWorks. Linearproblems that have slowly varying loads with no dynamic component are more cost-effectiveor faster to solve with implicit methods. Attachment My problem occurs when defining constraints and loads.

The default angle of theflooror other surface onto which the object drops is normal to gravity. Discrete element method simulation software enhances particle collision analysis, spring and damper motion, fiber modeling Analysis results can be viewed as contour plots of stress, displacement, and strains cosmosworkx all locations on a model, or at preselected locations such as vertices and reference points. Define as many as what-if design scenarios.

As for industry use, Solidworks is becoming more widely used than creo because creo is too expensive and is more cumbersome when it comes to doing
