Design Optimization Application In Accordance
With Product And Process Requirements

Abstract
Structural optimization techniques are a well-known approach for improving
product performances. Often, optimization procedures do not include
manufacturing constraints arising from corporate technologies. This aspect
becomes a disadvantage in the design review phase when the final product
release is a trade-off between optimization results and manufacturing constraints.
This paper describes a specific new approach, which considers product/process
guidelines an input/output data in the optimization phase. The study case is
represented by a high performance aeronautic seat structure having as mission
profiles the SAE-AS Standard, in order to demonstrate occupant protection when
a seat/occupant/restraint system is subjected to statically applied ultimate loads
and to dynamic impact test conditions. The authors’ aim, in accordance with
standards’ requirements, is to achieve a final design based on an optimized
structural solution for the chosen process technologies, taking into account the
low volume production and typical attitude of the aeronautical industry. The
presented study case offers the proper reference in order to extend this
methodology to more complex structural applications.
Keywords: topology optimization, manufacturing constraints, product/process
guidelines.
1 Introduction
The ability to introduce new products in a shorter lead time, to new and existing
markets is a dominant feature of companies operating in a concurrent
engineering environment [1, 2]. Concurrent engineering is also a comprehensive
approach to production of goods and integrates the design process with
materials, manufacturing methods, process planning, assembly testing and
quality control. Designers must be able to assess the impact of design
