From SolidWorks to SimMechanics 6

Posted by Guy Rouleau,

This week we see how to export a CAD assembly from SolidWorks to SimMechanics. Once a mechanism is translated into a SimMechanics model, we can interface it with Simulink to perform a wide range of analysis or design tasks not available in most CAD software.... read more >>

Motion Actuation in SimMechanics R2013b 7

Posted by Guy Rouleau,

Motion Actuation in SimMechanics R2013b In R2013b, it is possible to specify joint motion in SimMechanics Second Generation models. In this post, I will use a simple pendulum with internal friction and subject to gravity to highlight different ways to actuate a mechanism. If you look at the dialog of a joint like the Revolute Joint,... read more >>

Hyperloop Model Architecture: We want your feedback! 5

Posted by Guy Rouleau,

Hyperloop Model Architecture: We want your feedback! We had some fun in our last post about the Hyperloop open source transportation system, but we didn't get much into the specifics. This week we begin to move things forward. Before beginning to analyze the feasibility of individual components, we decided to think about how we would architect a Simulink... read more >>

From Symbolic to Simulink 1

Posted by Guy Rouleau,

From Symbolic to Simulink I am recently visited the MathWorks Japan office and learned about interesting work done by my colleague Hitoshi Takeshita. In his MATLAB Central submission Euler–Lagrange equation, Hitoshi shows how the Symbolic Math Toolbox can be used to easily obtain the equations of motion of a system by simply defining the energies... read more >>

SimMechanics Second Generation 15

Posted by Guy Rouleau,

SimMechanics Second Generation SimMechanics users, the first time you opened the Simulink Library Browser in R2012a, you probably noticed a big change: SimMechanics Second Generation SimMechanics Second Generation is a complete redesign of SimMechanics. Let's see what this means. A new way of thinking: Frame Centered In the First Generation, all rigid body coordinate systems are... read more >>

Applying Motion to SimMechanics Models 9

Posted by Guy Rouleau,

Applying Motion to SimMechanics Models One of the features I like about SimMechanics is the ability to specify the motion of a system without having to think about the forces involved. This can simplify testing a model so you don't have to design a controller if all you are doing is testing the plant... read more >>
