FEM for flexibility

In this section, we are mainly concerned with the impact of groove depth and wall thickness on the flexibility.

Because all the operations have been introduced in the previous section, we will only show the difference.

The following is our Assembly.

9 loads:

  • Step-0: all airbag  0.001Mpa(The airbag establishes contact with the arm)
  • Step-1: airbag-1    0.1Mpa
  • Step-2: airbag-2    0.1Mpa
  • Step-3: airbag-3    0.1Mpa
  • Step-4: airbag-4    0.1Mpa
  • Step-5: airbag-5    0.1Mpa
  • Step-6: airbag-6    0.1Mpa
  • Step-7: airbag-7    0.1Mpa
  • Step-8: airbag-8    0.1Mpa

So, we can get the result like this.

 We measured that area using Monte Carlo method. Furthermore, using L0, L1, R and D, the reachable space can be calculated by the formula. The calculated area approximately equals to the measured counterpart, which validates the calculation method.
