Applications of Advanced Composite Simulation and Design Optimization

Usage of fiber reinforced composite material entered an new era when leading aircraft OEMs took an unprecedented step to design and manufacture essentially full composite airframe for commercial airliners. Composite structures offer unmatched design potential as the laminate material properties can be tailored almost continuously throughout the structure. However, this increased design freedom also brings new challenges for the design process and software. Moreover, as a relatively new material, composite behaviors are more complex and less fully understood by design engineers. Therefore, reliable simulation for highly complex events like bird strike and ditching can play an important role in shortening the product design cycle. This paper showcases two area of CAE tools for composite applications. On advanced simulation, bird strike simulation with Altair RADIOSS [1] is demonstrated on an aircraft underbelly fairing. On design optimization, an airplane wing structure is designed using an innovative composite optimization process implemented in Altair OptiStruct [1-3]. OptiStruct has seen increasing adoption among aerospace OEMs, as demonstrated in the Bombardier application process described in this paper.

Forming Simulation of Woven Composite Fibers and Its Influence on Crash Performance

The automotive industry, in its constant quest for weight reduction, is increasingly considering composite materials as a substitute for sheet metal components to meet future fuel consumption standards. However, composite forming processes are expensive and difficult to control because of the complexity of the material behavior with fiber and matrix layers or plies and its dependency on many parameters, such as non-linearity of tensile stiffness, effect of shear rate, temperature and friction. Hence, numerical simulation could be a viable approach to predict material behavior during composite forming. The objective of this study is to highlight capabilities of RADIOSS™ to simulate forming simulation of composite plies made from woven fibers, each ply modeled as a layer of woven fibers along two directions of anisotropy, warp and weft. For validation the well-known double dome model published in NUMISHEET’05 proceedings is used. The compared result is the shear angle after stamping that is, the final angle between warp and weft fibers, at several prescribed points on the ply. The variation of this angle has a strong impact on material characteristics which severely deteriorates when a critical value is reached. Hence, a study on crash simulations is performed, after mapping fibers angles from stamping simulation.

A Multifunctional Aerospace Smart Skin Emerges from Computational Models and Physical Experiments

The capability to assess the current or future state of the health of an aircraft to improve safety, availability, and reliability while reducing maintenance costs has been a continuous goal for decades. Many companies, government agencies, and academic institutions have become interested in Integrated Vehicle Health Management (IVHM) and a growing effort of research into “smart” vehicle sensing systems has emerged. Methods to detect damage to aircraft materials and structures have historically relied on visual inspection during pre-flight or post-flight operations by flight and ground crews. More quantitative non-destructive investigations with various instruments and sensors have traditionally been performed when the aircraft is out of operational service during major scheduled maintenance. Through the use of reliable sensors coupled with data monitoring, data mining, and data analysis techniques, the health state of a vehicle can be detected in-situ.

Free-size optimisation was used to generate laminate boundaries, ply thicknesses and fibre directions, which met stress and displacement requirements. Physical testing carried out on manufactured parts highlighted the accuracy of the FE models and demonstrated the advantages of incorporating OptiStruct Optimisation tools in the design process.

Step Change in Design: Exploring Sixty Stent Design Variations Over Night

Traditionally, computer analysis has been used to verify the structural performance of a proposed stent design. The stent deployment process consists of multiple stages (e.g. crimping, springback, expansion etc.) which is highly non-linear inducing material plasticity and load transfer via component contact. A single structural verification assessment would require a couple of days to compute on a PC. This paper investigates how recent developments in Computer Aided Engineering (CAE) and computer hardware combine to facilitate the rapid exploration of many stent design variations. It is demonstrated that by utilising these technologies, over sixty stent design variables can be assessed overnight provides valuable design sensitivity information and an optimum stent geometry configuration. On an example baseline geometry considered the radial stiffness was significantly enhanced with an improvement in structural performance. This represents a step change in the CAE assessment of a stent design.

Since 2013, RUAG Space has been conducting intensive research and development work to investigate how to ‘print’ its components using an Additive Manufacturing (AM) process. The goal of the engineers was to take full advantage of the design freedom AM offers and to create an aluminum component that would be significantly stiffer while at the same time lighter than the original design. In addition, RUAG’s engineers also wanted to cut down design and development time to get results and the final component faster.

Heavy Duty: The Unique Thermodynamics of Heavy Vehicles

The heavy vehicle class — trucks, tractor-trailers, construction equipment, agriculture vehicles, etc. — is perhaps the “hardest working class in the business,” to borrow an expression. Not surprisingly, this class of vehicle presents some unique thermal management issues, distinguishing them from typical automobiles and presenting some distinct challenges when it comes to heat transfer modeling.

Structural Component Design Optimization for Additive Manufacture

Additive manufacturing (AM) technology enables the possibility of realizing highly efficient, optimized structural components with configurations not achievable using conventional manufacturing methods. The Altair and Solid Thinking toolsets provide advanced capabilities to design structural topologies to minimize weight and maximize other performance criteria. However, conventional manufacturing processes require application of design constraints, such as directional access for machining, in the optimization that limit the structural efficiency of the resulting design. AM can remove many of these constraints to allow for more efficient configurations under the applied loading conditions. Case studies show the potential to reduce weight up to 30% for components with applied bending and torsional loads by allowing increased complexity configurations that could only be manufactured additively.

From Incremental Change to Full Design/Validation Leap: A Multidisciplinary Approach to Optimize Safety and Crash Performance

Heavy-duty mining trucks at Hitachi are designed to meet ISO ROPS and FOPS safety requirements, while structures must be as lightweight as possible. The presentation will discuss Hitachi’s design and simulation approach, which consists of an integrated multidisciplinary analysis process. Dynamic analyses, multibody dynamics simulations, including flexible bodies and dynamic simulations are methods applied to optimize performance and vehicle safety. The author will present examples such as the optimization of a trolley support structure, a kinematics model of a 100-ton truck and the analysis of a trailing arm. Finally, the author will share his thoughts on the important subject of how simulation can better impact the design.
