NX Design Simulation – Lesson 1

Lesson 1 – Introduction   Tags: NX CAE, Design Simulation, FEA, basic, introduction In this introduction lesson for NX Design Simulation, we’ll have a general look at the application, and show you a best-practice workflow. By working like this, you can make sure that you take smarter design choices for your design, as well as being prepared for any changes that might come your way through associative geometry...

Motion Simulation – Lesson 1

Back to course overview Lesson 2 » Wave Pendulum   Tags: wave pendulum, introduction, motion simulation We’ll kick off the motion simulation course by animating a wave pendulum, as shown on the image above. During this lesson, we’ll elaborate on the differences between a kinematic vs. a dynamic simulation. Gravity would be the dynamic factor in this lesson.    Download the part file needed for this...

Motion Simulation – Lesson 2

Back to course overview « Lesson 1 Lesson 3 » Geneva Mechanism   Tags: geneva mechanism, 3d concact, dynamic simulation In lesson 2, we’ll look at yet another dynamic simulation. We will simulate the mechanism above, also known as a geneva mechanism. A 3D-connection has to be defined between the two geometries in order to force the desired movement.    Download the part file needed for this...

Motion Simulation – Lesson 3

Back to course overview « Lesson 2 Lesson 4 » Joints – Swingarm   Tags: universal joint, cylindrical joint, degrees of freedom, dof In lesson 3, we are going to simulate a swingarm belonging to a wheel suspension. In order to do this, we have to learn a little bit more about joints. We’ll introduce cylindrical and universal joint. We are also going to explain a little bit more about degrees of freedom (dof). We will not go through all the joints in this course, so we have summed up all the joints and their respective dof’s in the pdf below.

Motion Simulation – Lesson 4

Back to course overview « Lesson 3 Jack in the box   Tags: Jack in the box, screw joint, slider joint In this last lesson in this motion simulation course, we are going to simulate a jack imn the box mechanism. To do this, we have to introduce a couple of new joitns: Slider and screw joint. Also, we will see how we can add spring connections between components, as well as defining gear couplings between two gears.    Download the part file needed for this...

Finite Element Method – Lesson 5

Back to course overview « Lesson 4 Mesh Refinement   Tags: 3D mesh, mesh refinement, localize nodes In this final lesson in this course, we want to elaborate more about meshing. Often, you can get a bad mesh quality at certain areas, which can be solved by refining the mesh locally. This means that instead of refining the entire mesh, you can pick certain faces to refine. We will also look at how you can localize the node in the mesh which is exposed to maximum force.  Download the partfile needed for this...
