AI Thread Summary
To verify the accuracy of a complex multibody model, performing hand calculations is recommended, either for the entire model or a simplified version. Simplifying the system through methods like linearization can help in understanding the mechanics involved. This approach allows for easier validation of the model's behavior. Engaging in both hand calculations and simplifications can provide a comprehensive check on the model's correctness. Ultimately, these methods ensure the reliability of the multibody simulation results.

Hi all,

I have just created a multibody model of a mechanism. Since it's a bit complex to perform hand calculation, what should I do to check if it's correct?

Thanks

Do the hand calculation anyway? Or do a hand calculation of a smaller simplified version of it?

Ja, you're on right, I think i should be able to simplify the system, maybe through linearization and so on. Thanks!
 
Posted June 2024 - 15 years after starting this class. I have learned a whole lot. To get to the short course on making your stock car, late model, hobby stock E-mod handle, look at the index below. Read all posts on Roll Center, Jacking effect and Why does car drive straight to the wall when I gas it? Also read You really have two race cars. This will cover 90% of problems you have. Simply put, the car pushes going in and is loose coming out. You do not have enuff downforce on the right...
I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly
Thread 'What's the most likely cause for this carbon seal crack?'
We have a molded carbon graphite seal that is used in an inline axial piston, variable displacement hydraulic pump. One of our customers reported that, when using the “A” parts in the past, they only needed to replace them due to normal wear. However, after switching to our parts, the replacement cycle seems to be much shorter due to “broken” or “cracked” failures. This issue was identified after hydraulic fluid leakage was observed. According to their records, the same problem has occurred...
