DMU Kinematics

Assalamualaikum and very good day.

For those who are trying out DMU kinematics to complete projects or just learning, there are few different approaches. If you guys have downloaded Dick Sham tutorial about excavator kinematics, it come with different approach. Such as, you need to have you constraints selection very well in Assembly Design, and then use the Automatic Conversion in DMU Kinematics and all are converted systematically. But how if you did not know how to the very well constraints in Assembly Design?

Another approach is to apply the contraints in the DMU Kinematics. These are the steps:

1. Open your Assembly in Assembly Design.
2. Switch to DMU Kinematics.

3. In DMU Kinematics, select icon for Fixed Part, by creating a new mechanism in the appeared window, and selecting part that are fixed (not moving) will end up with a trees appeared under the history tree.

4. Next, Hide all the parts except the fixed part and part that will be connected to the fixed part which will moving prior to your projects.

5. By selecting proper constraints such as (revolute, cylindrical, planar,..etc), in the Kinematics Joints use this command to create contraints between your moving part and your fix part.

6. Apply commands to the constraints, usually shown by angle, or distance.

7. And when you click OK, if a window appear and saying that "Your simulation can  be simulated", so, you have succeed to simulate your first simulation.

8. Use simulation icon in DMU kinematics to manipulate your catia parts.

9. Next, use Rigid icon in constraints, and rigid the parts with either the fixed part or the moving parts.

10. Capture your animation with video capture software otherwise it will have a huge data to capture with catia software.

For a conclusion, there are few criteria that you need to accomplish that are:

1) At least 1 Fixed part is needed.
2) At least 1 Kinematics Joint is needed.
3) At least 1 Command is needed.

And start with few parts first. You also can look for how DOF (degree of freedom) effects your kinematics success. Search for CATIA V5 Kinematics Help in google.

Below is a good sample on how this approach is used to do kinematics in catia v5.

CATIA V5 - Different thickness in a single part of file

Assalamualaikum wbt.

A video showing how to do different thickness in a single part of file. The process start with a wireframe and surface, then divided by few portion. The important idea is, to create few geometrical sets so that it is divided into different portions. Then, In the part design workbench, thickness command is use to do thick to each of the splitted surfaces in the respective geometrical sets.



Thanks to Mr Tasbirul Islam from Bangladesh and Prof Baharudin from MALAYSIA to include me in the conference paper for relating to this method. You can read it here. Thank you. Wasalam. (Update 21-12-2016)

Poster sample for EMD 112

Assalamualaikum and good afternoon.

This is a poster's sample tips that can be used to describe your positive value of your product. This poster also explains the title and also the team members in the group. Logo is optional.

Sorry for the late post. Anyway I have explained this in our previous lectures (Catia photo studio)
 Good luck my fellow students!

Creating Airfoil by using VB

Do you always come to a point where how do i insert thousands of points into catia without inputing it one by one, and keep thinking there is no end and do i made mistake in my previous points?

Watch this video and learn how to create airfoil using Visual Basic.

Boeing AH-64 Apache with Catia V5

Assalamualaikum wbt.

Helicopter is an air transport that have a main rotor blade to create lift, and a tail rotor to counter its torque. A helicopter is also an air transport that only need a space of its size to take-off as its capability of Vertical Take Off. With this capability, its have its advantage comparing to fixed wing that need space for its runway.

But in other context, designing a helicopter in a software is quit challenging. Its need passion to complete the helicopter from its cockpit to the tail. And, today i have found this video link in the youtube created by Alberto Cerrudo with his Boeing AH-64 Apache.

I have seen quit a lot of fized wing airplane reverse engineering a fixed wing, as i also done it with my Boeing, but this is very different. To reverse engineering a helicopter in a software/ catia is a good effort and differs from other. And yes, to own a helicopter, you will need a very big amount of cash, but in term of designing and have it in your computer, and designing on your own is quit a satisfying experiences.

Congrats to the Alberto for his effort on designing Boeing AH-64 Apache.
