Kinematics Hose movement simulation analysis

Kinematics Hose movement simulation analysis

Hoses are generally used to convey fluids when a tube cannot be used because there is motion or vibration between the connection points. It would be awesome if Creo would have a tool to simulate the behavior/motion of a hose on a pivot or slider joint mechanism and analyze/optimize the hose length and slack to be able to meet all the positions in the mechanism and show the stress concentrations and bend violations or failures.

 

This tool could also be used for cabling simulation.

I agree with this. For me, this could be done by improving the multibody concept in a part, to allow certain bodies inside the part to have degrees of freedom, just like an assembly. Then, a the first tip of the hose or wire could be modelled between the first rigid body at the origin, and the second tigid tip of the hose, at the second mobing body. In bewteen the fixed and the moving body, a spline would be used to make a sweep to connect the two tips of the hose or wire. This would constitute a real "flexible" or "soft" component, and when puting it in an assembly, the user would be requested to assemble both tips, since it's not a single rigid body, but two rigid bodies (with one moving or having degrees of freedom relative to the other), the user would be asked to assemble the two rigid bodies (the two tips of the hose or wire), as if he was assembling two components. If the user assembles the two tips of the hose to two different components of an assembly, that move one in relation to the other, the software would produce change in real-time the path of the spline used for the sweep that connects the two rigid body tips, interpolating the geometry vertices position, as done by any animation software package. It can even be animated in a OpenGL program inside the graphics card to have a real-time animation, with now slowdowns. Only if the user wants to have colition detected, should the work be done by the CPU, even if in this case, the animation might not be possible to calculate in real-time, but as a simulation analysis.
