Motion Actuation in SimMechanics R2013b

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 10

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 >>

Model-Based Design of a Dicycle 4

Posted by Guy Rouleau,

Model-Based Design of a Dicycle The other day I found this video: If you watch carefully, you will see around 1:50 that they used Simulink to design their controller. So for this week's post, I thought it would be interesting to see how we can design a simple planar version of a dicycle in Simulink. Modeling the plant... read more >>

Model-Based Design of a Hydraulic Press 4

Posted by Guy Rouleau,

Model-Based Design of a Hydraulic Press  Today guest blogger Arnaud Miege presents a great example of adopting Model-Based Design. As an application engineer, I meet lots of customers applying MathWorks tools in many different and cool ways. Recently, a customer who manufactures hydraulic components and large-scale hydraulic systems, such as hydraulic presses, wanted to adopt Model-Based Design... read more >>

Visualizing Simscape data 2

Posted by Seth Popinchalk,

Visualizing Simscape data  By Guy Rouleau Today I want to introduce one of my favorite submissions on MATLAB Central, the Simscape Simulation Results Viewer. Working in technical support, I often receive requests from customers asking for help when their custom component created using the Simscape language does not behave as expected. Before Simscape 3.3... read more >>
