MOTION ANALYSIS

MOTION ANALYSIS

Motion Analysis is used to analyse a assembly or part when it is in motion. It helps to understand what kind of output motion is going to be given by the assembly. It also enable us to check whether the output given by the assembly is correct or not and if not correct, then where amendment is required. 

Motion analysis also gives the advantage of analysing a part dynamically i.e what kind of forces are going to act when the given part is in motion.

Solidworks motion simulation contains various inputs parameters and output parameters.

Motion Analysis can be found only in assembly files. It has several features related to the motion of an assembly file. 

Features of Motion Study:-

Motion Study Tab – This tab allows us to analyze the motion study of the assembly file.

Motion Manager Tree – This contains all the parts, sub-assemblies, mates, and the simulation elements.

Calculate – This button allows calculating the motions of the assembly and helps to update after changes made.

Play – This button allows us to play the animation to see how it works after calculating the motion.

Playback Speed – This helps to reduce or increase the speed of the animation.

Save Animation – This button helps to save the animation as a video.

Motor – This allows simulating a motor or giving a torque to the animation such as at pin connections.

Spring – This allows simulating a spring in motion where you can edit the spring constant and length.

Force – This allows simulating forces on any part of an object.

Contact – This allows stopping the interference between solid objects and adjusting the friction between objects when it is in motion.

Gravity – This allows simulating the effect of gravity on solid objects.

Results & Plots – This allows getting the results and plots for displacement, velocity, force, angles, etc.

Zoom Time Scale – This allows zooming in/out the timeline.

Key Point – This point decides where the motion has to be stopped.

Time line – This shows the moving time frame

MATES :-

Mates are very crucial from analysis point of view as they define what kind of contact is there in between the various parts of the assembly. Mates defines the motion that is going to be taken place between the various parts. There are different types of mates viz. Revolve, helix, coincident, parallel, etc.

These mates defines the type of contact between the parts of assembly.

SOLID BODY CONTACT :-

Solid body contact are used to define the type of contact between two parts of the assembly i.e. if both parts are solid and do not penetrate in each other then this type of contact.

For practical example, watch my video of Oscillations of balls by BSB TECHNOCRATS on Youtube.
