  • What is explicit analysis?
  • Purpose 
  • How to do explicit analysis?
  • Conclusion

Method:

  • What is explicit analysis?

structural analysis is divided into two part linear and non-linear, again the non-linear part is divided into two part implicit and explicit.

Linear analysis- where stifness and mass is constant and no change in displacement so no velocity and acceleration.

Non-linear analysis:where the displacement of the body changes and due to this stifness also changes. It is divided into two- implicit and explicit.

Implicit- creep, quasi static analysis where change is very slow.

Explicit- fatigue, crush, fall etc where change is very fast. so time is very short in case of explicit.

 

  • Purpose 

To find out various property of the product to make it safe e.g. car crash analysis, mobile drop analysis, bullet crash analysis.

Here we will discuss bullet crash analysis

  • How to do explicit analysis?

First drag explicit analysis

Draw the model in designmodular

 

open Model- after meshing we are giving boundary conditions- fixed support at the edge of the model

velocity 550m/s at -z direction

Then in the solution tab- total deformation , equivalent stress, directional deformation at z axis and equivalent strain.

Outputs:

Conclusion:

In explicit analysis we can find out the amount of energy , displacement , velocity and other properties of the model .

Modal Analysis using Ansys Workbench

  Modal Analysis   using Ansys Workbench : AIM: What is modal analysis? Purpose of modal analysis Types  How to do model analysis? Conclusion Analysis What is modal analysis? Modal analysis look for natural frequency and normal mode of  a structure.Natural frequency and modes are some of the important factors of a structure, they determine how the structure will respond .   Purpose of modal analysis By knowing naturing frequencies of a component we can design them to avoid specific ranges to prevent resonance.In this way we can design from car components, buildings, blades and any other component to prevent faliure of the structure. Types  Here three types of model analysis will discuss three types of model analysis- 1. Free free model analysis(models which are free to move like drones , boats , aeroplanes etc) 2. Models which have fixed boundary condition 3. prestressed model analysis(models which have an initial stress condition) How to do model analysis?...

Engine Block Design And Assembly in Solidworks

  Engine Block Design And Assembly in Solidworks AIM: 1. To Design parts of Engine Block 2. Assemble Them 3. Create Animation   Method: Parts of Engine Block- 1. Connecting Rod : On the Front  plane WE have drawn The two circle below and then extrude them upto 20mm Then Again in the front plane - sketch we joined the two circle by spline and extrude them as middle upto 12 mm     Then on the right plane we drawn a straight slot and cut extrude this through all by offseting 6mm  Then we mirror this on the other side   Now our connecting rod is ready. 2. Crank_shaft  :     First Sketch : on Right plane Boss Extrude 25mm Then sketch on previous plane and boss extrude upto 8mm Again sketch below structure and boss extrude upto 15mm Boss extrude -4 : Now we have to mirror the below surface so first select the round surface and sketch   Boss-extrude-5: First select the upper surface and convert the sketch entity and rotate it by 90 degree ...
