I encounter a difficulty that perhaps some people might experience.
I would like to study the trajectory of the water jet in the tank during the rotation of the nozzle and the washing head (see attachment).
What is the method(s) you recommend to me?
So far, I can easily make the rotational movements but how can I "record" the points of passage of the water jet on the tank? FYI, I'm working on SolidWorks 2014 with a Premium license.
Thank you in advance to all of you. Have a good end of the day.
I don't really see a tool that can help you, but there may be a trick to find!
A few questions already: are these rotations at linear speed? Are they synchronized? Is your nozzle rotation going back and forth during a continuous rotation of the head, or does this nozzle rotate endlessly?
A trick might be to draw a volume representing a movement of the nozzle, and repeat it by rotation, so that you can see after how many iterations the surface of the tank has been completely "touched".
No, you don't have to take into account the kinetic force distorting the trajectory. We will consider that the jet is straight and not deformed, it will already be not bad!
I tried to remove material at each end of the jet to "perforate" the tank but no possibility to record the impact points.
The speeds are constant for the two rotations and not synchronized (one rotates at 30 RPM and the other at 20 RPM to give an idea). The nozzle rotates endlessly and is dependent on the rotation of the head.
The idea of representing the jet and repeating it by rotation can be interesting, at least to materialize the points of impact.
To have only a curve with the points of impact on the tank, I don't know. On the other hand, on CATIA I know that it is possible to record a volume corresponding to the movement of the parts. I guess there must be the equivalent in the motion.
By modeling the cylinder corresponding to the water jet (the length would be the length up to which the jet can be considered effective), we can then give it the rotation speeds of the head and the nozzle (and possibly the longitudinal displacement of the head if this is the case). From this, we can generate the volume swept by the water jet for a time t.
It is then sufficient to limit this volume to the diameter of the tank. The outer surface then corresponds to the surface swept by the water jet on the wall.
Chamade, I understand the principle you give on Catia, I don't know if it's feasible on SolidWorks. But the idea is exactly what I want to do!
Stefbeno, the trajectory is modeled via the motion study where I give the values of the rotation speeds of the nozzle and the head. After how to switch to volume scanning during a motion study... This is where it gets messy!
Hello, I don't think it's possible to go from Motion to a swipe, as I said above, you will have to go through a 3D curve driven by an equation... An example. . http://www.dailymotion.com/video/xcqfel_solidworks-3d-curve-equation-driven_auto
You can forget about Flow simulation because it is not possible to simulate a flow of a free jet. On the other hand, have you tried with the Axemble DriveWorks utility? The result will not take into account the deformation of the jet when impacting a surface but you will have the volume swept by your jet.
The operation is simple, you specify the movements (nozzle rotation, head rotation), the time increment and driveworks creates a volume at each position
Attached is a screenshot of a study of a movement of a part
Due to a technical problem, we cannot highlight @y.pacquelet's answer as a better answer. On the other hand, I'm going to assign the points to you manually.
