![]() If the Hinge Plate adds significant stiffness to the rib, then Rigid might be a good choice. You have to choose how the scoped areas of the Joint behave: Rigid or Flexible. Add a Revolute Joint scoped to those two areas and align the revolute axis in the correct direction and in the correct location. What does the hinge look like? A door hinge has two rectangular plates connected by a pin.Ī simple way to model the hinge in a system model is to imprint on the rib the two areas where the hinge plates fasten to the rib. ".The contact and target side which you defined do not look very realistic to me, since they are in no way connected to each other right?", Was this for the contact between the tube and the rib or the contact between the ribs? The other holes that your see they do not have major structural components (it's for cables and weight saving). You recommend me to use a bonded contact between the rib holes (the ones that have a tube passing by) and the tube, is that it? (they are not allowed to rotate). Sorry I did not understood very well, the problem with the contact targets. ![]() Thus, I used a bonded contact between the two surfaces. As such, when in flight, it is hoped that they do act one piece, as they were bonded. It's the hinge that hold them together and the tubes are use to transfer the load from one outer part of the wing to the center. However, indeed the two ribs are not connected. I have been having very good results overall, the only problem in this part of the simulation. Do you think that, I should add it to this model? It would increase contact complexity and I just want to have a overall idea of wing displacement and stresses. I was thinking of doing a local model wing the hinge in mind and use shared topology and results from this simulation. I did not modelled it because I wanted to have a global model of the wing. The locking mechanism, is a just a simple hinge (not modelled) that guarantees the continuity of the wing. Thank you for the explanation between mesh connection and using bonded contacts, I was not aware! You can see this happening in the last image, near the rib pipe intersection. Using a mesh connection distorts mesh elements in many cases. Also, there is no need for a mesh connection if you are using a bonded contact. If there is a stud running through these holes you can connect them with a revolute joint (if they are allowed to rotate) or a fixed joint/bonded contact (if they are not allowed to rotate). The contact and target side which you defined do not look very realistic to me, since they are in no way connected to each other right? I also see 2 more holes (one front, one back) on the ribs. If the ribs are fixed on the pipe at the holes then you may define a bonded contact between the edges of these holes and the pipe surface. ![]() Since the locking mechanism is not known its hard to tell what might be the most accurate way to define the contact. ![]() The latest generation of Cetus3D is named MKIII,which added heated build plate,then customers can use it print not only the PLA material but more materials like ABS,PC,ABS+ etc.and the MKIII will provide options to upgrade the anto-leveling function.".there is a locking mechanism (not represented) that bonds both wing together" - The contact should most accurately represent the force transfer via the locking mechanism. The Y-axis is carefully calibrated in the factory, so users can start printing right out of the box, and there is no need to level the machine before getting to work! This ensures that the build surface is flat and parallel along the X-axis. It is fixed onto the linear guide directly, and there are no moving parts between the slider and the build plate. The build plate for Cetus3D is a 3mm aluminum plate, which ensures a perfectly flat build surface. Cetus3D is a subsidiary of Beijing Tiertime Technology LTD.As a truly essential system, the body of Cetus3D is made of aluminum extrusions,the XYZ axis all using stainless steel liner rail,and the machine is simplified into only six modules.There are 3 nozzle options with the preset profiles, 0.2mm, 0.4mm and 0.6mm,which can meet different requirement of print accuracy,Cetus3D printer has 2 verstions,the Standard version and the Extended version,The standard version provide a print volume 180(W)x170(H)x180(D)mm/7” x 6.6” x 7” and the Extended version has a bigger print volume 180(W)x280(H)x180(D)mm/7” x 11” x 7” The Cetus3D 3D printer is an affordable 3D printer made by Cetus3D, a manufacturer based in China.
