Advantages of FEM Simulation
Some industries requires components that are light yet extremely stable. When it comes to rapidly optimising diametrically opposed requirements such as these, FEM simulations are often the first choice. Based on a FEM model, the mechanical stresses can be calculated and displayed in 3D colour diagrams. Thus, this innovative method can be used at an early phase of product development to determine whether or not an intended design will be successful.
Starting point is the original side wall of the ATR with dimensions of approx. 500 x 500 mm and a weight of just 2,500 g.
For example, this method was implemented to design a significantly lighter ATR (air transport rack) with nearly identical stability values. How does a rack like this behave when exposed to vibrations and impacts? Which vibrations, dynamic torsional loading and static stress occur in the rack structure?
The reduced weight of the side
wall - a honeycomb structure based on an aluminium alloy - offers similar stability with a mass of just 1,300 g.
Based on the customer's specifications, a solution was developed and tested in a lab through initial simulations. From the FEM simulation, a design was created for the entire system and then manufactured for the customer.
By using FEM during the initial development phase, one can be sure in advance that the product to be tested will be a "winner" thus saving a lot of further development and test time.
