MechAnalyzer® is a 3D model based software developed for effective teaching and learning Mechanisms related courses. It is an evolving product developed in Mechatronics Lab, Department of Mechanical Engineering at IIT Delhi, New Delhi, India, under the guidance of Prof. S.K. Saha. It is freely available for academic usage.

​We would like to term this as "Priceless Software" as it has immense value for a zero cost. Similar to MechAnalyzer, another software developed by us to teach and learn Robotics is named RoboAnalyzer®. Visit the RoboAnalyzer homepage here.​

Announcements

• MechAnalyzer Team (through FITT, IIT Delhi) has entered into an exclusive license agreement (India and International) with Authorised Partner for the Sales and Support of MechAnalyzer (after Version 6). Please contact Authorised Partner for further details.

• ​Recursive Dynamic Simulator (ReDySim) has now User Friendly GUI in MATLAB. More details here.

Study of various planar and spatial linkages is covered in Mechanism Design, which is a basic course taught in the curriculum of Mechanical Engineering. Students learn the kinematic and dynamic equations to analyze different types of mechanisms. A computer-based approach to solve these equations becomes imminent when the number of equations increases and also for a quick and better understanding through visualization. Currently, there are many commercially available software which can help students in this matter. Unfortunately, considerable amount of time is required to train students in order to use them.​

​MechAnalyzer is a free software developed to simulate and analyze the mechanisms that are already preloaded in it, hence, reducing the time and effort required to get started with it. The software has been developed in C# and uses OpenGL/OpenTK for visualization.
​
It is a software under active development. Screenshots of the current version are available below. All the versions that have been released so far are listed in the Downloads page. ​
