How to establish a robust data / information exchange between product-independent design element assessments & product-specific load derivation and load path design?

Motivation

Only with standardized load path methods

transparent requirements for design elements

can be derived

Standardized load path methods as enabler for

tool based, automatized evaluation of design

elements in mechanical architectures

Load derivation from a system perspective

?Cut out design elementfor product integration

Democratization in CAE-based product

development means to empower non-

experts to take advantage from simulation

technology

CAE experts could put the power of

simulation safely into non-experts hands to

overcome the general lack of CAE engineers

Democratization ?
