Materials

We design and analyse products made from the following materials:

  • Steel and stainless steel
  • Aluminium
  • Titanium
  • Carbon or glass fibre composites including sandwich designs with honeycomb or foam cores
  • Engineering plastics

 

3D CAD Design

  • CAD modelling using the latest parametric software
  • Photo realistic rendering for brochures and presentations
  • Design of welded, bolted, bonded and riveted joints
  • Design optimisation for manufacturability, mass, cost, fatigue, stiffness or strength

The key to successful product design is an accurate 3D model. A 3D model allows checking for part fit and interferences especially when parts move relative to each other. Design integration between mechanical, electric, pneumatic, HVAC and other systems is also much simpler since everybody can see each other’s components.

When it comes to presenting the product to non – engineers it is easy to produce photo realistic renderings to illustrate design solutions and issues.

An accurate 3D model is also the basis for FE analysis and CNC manufacturing. Files can be easily sent to stakeholders all over the world.

 

Analysis

  • Hand analysis using Excel spreadsheets
  • FE analysis of metal or composite structures ranging from simple linear static to transient dynamic to simulate impacts
  • Fatigue analysis to the latest standards

Many simpler structures can be analysed quickly and conservatively using classic hand methods. Excel is a great tool for this especially for design optimisations where the effects of different parameters have to be evaluated.

FE analysis is appropriate for parts with a difficult geometry and where highly accurate results are required. Model sizes range from small parts to whole train carriages or yacht hulls.

We have experience with many advanced analysis methods taking non- linear geometric behaviour and material properties into account. With transient dynamic analysis time dependent loads like projectile impacts can be examined.

Hand or FE analysis results are used to calculate the fatigue life of a structure. Local stress concentrations or welds in the wrong spot can significantly reduce the useful life of a structure. We use our experience to propose a better design solution with increased fatigue life or design repairs for fatigue cracks.

 

Systems Engineering

  • Writing or review of specifications
  • Requirements tracking
  • Testing and verification of requirements
  • Compiling of documentation, test and analysis reports

Projects in the aviation and rail industries usually have stringent systems engineering requirements to ensure design solutions meet the specification and are safe. This process can be quite daunting for companies who are not used to this. We are happy to assist with all aspects from the review of specifications, determining compliance with the specification, identifying how requirements are going to be verified and documentation of the whole process.

 

IP Protection

International IP protection is of great importance when new products are developed. We have obtained and licensed international patents for a method to control yacht winches electronically. Therefore we are able to assist with the patent process, examine prior art and evaluate costs and benefits.
