System sizing


A technical brick which has become essential in the design phase of your products and equipment, mechanical sizing is our historical core business at Inoprod. We produce pre-sizing and validation design notes with practical sense and a real knowledge of physics.
Our studies are executed based on analytical and finite elements models (FEA).

You are seeking:

  • Assistance with your development rationale, we produce the design notes
  • Optimum performance, we produce design optimisation studies using cutting-edge digital methods. Search for the optimum weight/performance/price ratios.

We respond with this skillset:


  • Linear
  • Non-linear (contact, materials)
  • Buckling
  • Pressurised elements
  • Transmission (coupling, bearings, power, gears)

Design optimisation


Design Optimization - Inoprod


As part of the technological development of its product, our customer wanted to validate and optimise the performances of a component dependent on the manufacturing procedures and the hyperelastic nature of the material.


  • Determine a new geometry that would be viable in operation, taking into account the different variations
  • Validate a new production mode for the component

Complexity of the model:

  • Experimental design
  • Non-linear contacts with and without friction
  • Hyperelastic material
  • Unstable behaviour of the component

Solution provided:

  • Orientation of the new geometry (component/environment distance, profile, etc.)

Customer benefits:

  • A new production method validated
  • Knowledge of the behaviour of the component in operation
