Our assessment of the APM 300R under-attachments took place as part of a replacement and fleet extension project. The main consideration was the under-attachment parts had to be optimised for weight.
Scope
To perform Finite Element Analysis (FEA) for the Coupler Mount, Lifting Jack pad and Ring Bearing considering given static loads – optimising the weight and ease of manufacturability
Create 3D models and drawings, once the design is approved by client Bombardier
Solution
We delivered an Input study of the existing coupler mount, lifting jack pad & ring bearing design
We prepared the mesh, loading and boundary conditions in Hypermesh pre processing software.
Our team ran the analysis for the identified load cases in Optistruct and evaluated the results for stresses and displacements
When this was carried out, we finalised our optimal design
Features
Reduction of weights by providing the cutout
Provided the optimised design and defined the welding parameters
Benefits
Optimised design solution, without changing the fixation points or bolts
