Mechanical CAD Simulation software - Free Download:Free Tutorial:Free Video Tutorial:Models&Examples

Dear Friends

I have been asked to suggest a Free Simulation Software for Mechanical linkages by one of my blog reader. Even though I know few simulation software's which are available as stand alone product or comes as a add-on product with CAD package. The point is the person wants for personnel usage and want to know about simulation. So I would like to Suggest one website where you can simulation software available for free(Demo Version).

The site name called AR-CAD, which offers four simulation software's for free of charge(certain cases Demo versions are available). They not only offer the software, also they provide Tutorials(even Video Tutorial in certain cases),with examples and Models to work upon. Their motto is to make people understand about how mechanism works based on the linkages defined by the user. Certainly this helps user to see how designed product works with virtual simulation. Isn't great ? The following are the product available:

freeCAD is a basic 3D CAD with advanced Motion Simulation capabilities. It is suitable for anyone interested in learning 3D CAD and Motion Simulation for free before using more sophisticated packages. Educators, students and new engineers will find it ideal for the teaching and learning of geometry, kinematics, dynamics, vibrations, mechanisms, linkages, cams, machine design and physics. The program runs on Windows, Linux PC, Macintosh PPC and other Unix's. Assembly data are unchanged across platforms.

CADSM is a basic 3D CAD with advanced Motion Simulation capabilities. It is suitable for anyone interested in learning 3D CAD and Motion Simulation inexpensively before using more sophisticated packages. Compared to freeCAD, it has the following extras: color, rendered graphics, 6DOF actuator, DXF file import for parts, faster upgrades and web support. CADSM is a commercial software with a free evaluation period of 30 days.

StCAD' is a basic 3D CAD framework in Smalltalk (VisualWorks 7.x). It extends the GF/ST 2D drawing framework into 3D. It also include 'StGeo' which is the 3D geometric domain, 'StMath' which provides the mathematical support for 3D CAD and motion simulation computations, and 'StDoc' which is a simple word processor. 'StMath' is also suitable for engineering, scientific and business computing. The parcels are open source using Lesser GNU Public License.These parcels can be used with other private software to create 3D applications like motion simulation, FEA, CAD, scientific visualization, etc.

Alibre MotionTM is a Motion Simulation add-on, available in Alibre Design Expert 9.1TM. It uses Multi-Body Dynamic analysis on an assembly created in 'Alibre DesignTM' for analyzing the behavior of mechanical assemblies with moving parts. Albire software is already discussed in my blog, for more details visit previous blog articles.

I guess all these software's has unique features, can capable of predicting the results like other simulation software's. So go through the description of each software download the one which suits to your requirement.
