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. Saha.It is freely available for academic usage. But making a 3D model sounds hard I’ve got some news for you: making any model will take time.It’s probably the most time-consuming part of a simulation study. Shaving weeks, hours and days off the model building process is probably the greatest benefit simulation software provides (besides solving your actual problem, of course).
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. Its motion simulation capabilities are comparable to the best and can provide accurate answers to engineers and scientists in diverse fields. This is the repo for the bepuphysics v2 library, a complete rewrite of the C# 3d rigid body physics engine BEPUphysics v1. The BepuPhysics and BepuUtilities libraries target.NET Standard 2.0 and should work on any supported platform.
freeCAD is capable of full 3D pan, zoom, tilt and rotate on an assembly of parts in wireframe or rendered graphics. Parts can be solids or DXF file imports. Available solids are extrusions of rectangles, circles, ellipses and polygons. The parts can be positioned and oriented exactly in space, as are markers on the parts. Exact specification of linear and angular velocities of parts in space are also possible. Mass and inertia properties can be user specified or automatically computed based on uniform density. Available joints are spherical (ball), revolute (pin), translational (slider), cylindrical, planar, fixed, universal, point in line, point in plane, parallel, perpendicular, no rotation, constant velocity, rack pinion, screw. Both open and closed 3D loops are permitted. The curve-curve contact allows liftoffs and collisions based on coefficient of restitution. Available actuators are rotational, translational and full six DOF. Their motions are user prescribed functions of time. Forces and torques are user prescribed functions of time, displacements and velocities in all three components or along connecting markers. Example formulas for spring, damper, bushing, beam, aerodynamic, inverse square law and other forces and torques are given. Available functions are sqrt, exp, ln, lg, sin, cos, tan, arctan, arctan2, spline, spectral density. Users can specify constant gravity of arbitrary magnitude and direction.
freeCAD can compute kinematic, quasi-static or dynamic solutions for any interval of time going forward or backward based on the assembly and user requests. It does redundant constraint removal automatically and nondimensionalizes the equations for improved accuracy and stability of models that are microscopic or gigantic. Simulation progress is animated and the simulation can be stopped any time. After simulation, the computed solution can be used for animation or frame by frame analysis. Full 3D pan, zoom, tilt and rotate is available during simulation and animation.
Users can obtain engineering data in the form of plots and tabular output. XY plots can be zoomed and set to equal scales. Data series available include linear and angular displacements, velocities, accelerations, forces, torques, momenta and kinetic energies. Acceleration data include transverse, centripetal and Coriollis accelerations. Users can view forces and torques from joints, constraints, actuators, springs, dampers, applied forces and inertia. Fourier tranforms of all times series are available. Individual parts can be save into files and reinserted into any assembly repeatedly. Assemblies can be saved in binary or human readable, tab delimited, text format with notes and simulation data for later reload. The text format allows pre and post processing of assemblies by other programs, especially spreadsheet programs. Other specific text formats are for MOSES, PDMS Review and POV-Ray. freeCAD runs on Windows, Linux PC and Mac OS/X. Assembly data are unchanged across platforms.
