Driving Aerospace Competitiveness - INESPASA Accelerates Design of Aero Tooling Structures Using Altair SimSolid®
With more than 35 years of experience in research & development projects INESPASA has been working with companies such as Airbus, Alestis, Boeing, and Renault. To be successful in a highly competitive market, aeronautical tooling companies like INESPASA must deliver maximum quality and comply with highly demanding standards and regulations while meeting tight time constraints and limited budgets. Developing and testing aircraft component prototypes is time consuming and expensive, so INESPASA had to find new and faster ways – like Multiphysics simulation – to evaluate its aero-structure designs, identify problems before they occur, and ensure viability.
INESPASA turned to Altair and applied tools such as Altair SimSolid®, Altair® Inspire™ and Altair® MotionSolve®. Thanks to fast simulation results, INESPASA addressed their challenge and found the solution with the best weight-stiffness ratio providing optimum usability of their aero structure elements.

Fly High with Optimization - Optimizing Camcopter® S-100 Design at Schiebel
Unmanned aerial systems (UAS) are a rapidly evolving technology and used for a variety of civil and military purposes. To ensure airworthiness, UAS manufacturers rely on advanced simulation and manufacturing techniques to create efficient designs. Aerial systems active throughout Europe and operating with diverse payloads for different missions require a reliable vehicle architecture and fuel supply. To ensure perfectly tuned architecture and a lightweight design while increasing stiffness and strength, Schiebel used Altair solutions in combination with 3D printing. The engineers performed various simulations to optimize the design of AM engine parts. Using Altair’s topology optimization structural design tool, Schiebel reduced the weight significantly while maintaining high stiffness. Subsequently, the system was evaluated by laminar and turbulent flow simulation as well as conjugate heat transfer simulation using Altair CFD™. Contacts, NLFE and complex dynamic systems were modeled with Altair® MotionView® and Altair® MotionSolve®. Schiebel also took advantage of APA solutions.

Outsmarting Heavy Equipment Design
Heavy mobile machines consist mostly of production equipment working almost twenty hours a day, year on year, in diverse harsh environments, undergoing extreme loads and overloads. Especially diggers and loaders such as hydraulic excavators, wheel loaders, and backhoes, cater to multiple applications with use cases such as digging, trenching, loading, lifting, breaking, and ripping. Many times, these machines undergo non-standard uses where the machine is subjected to unplanned forces and moments as in the case of self-loading on a trailer, or a bucket hitting a dump truck body. This paper highlights the workflow process and simulation-driven methods to integrate multi-physics with Altair’s industry-leading solutions. The latest generation of Altair simulation tools can capture a wider range of vehicle systems and environmental interactions.

A flexible tire model for accurate prediction of off-road vehicle dynamics on soft soils
For several years now, co-simulation between Multibody Dynamics (MBD) codes like MotionSolve and Discrete Element Method (DEM) software like EDEM has been used for many applications such as vehicles and material transportation. One missing link has been a realistic tire model that not only could interact with the soil material in a realistic way but also show the influence of varying tire pressure, change in contact area and pressure distribution over said contact area.
For very soft material such as deep mud with a high-pressure tire, using a rigid wheel is a decent approximation. But for tires on harder surface, this method has several short comings. For example, a rigid representation of the tire will have neglectable rolling resistance while the pressure distribution on a real tire has its peak well ahead of the centerline of the tire producing a resisting moment to the motion. The contact patch area will in reality not depend on sinkage, but the sinkage is dependent on the contact area that is dependent on load and internal pressure.
This presentation introduces the new PM-FlexTire model that is integrated in EDEM and will work with MotionSolve. Requirements for creating and correlating the tire model is presented together with several application examples on mud, clay and gravel beds.

Creation of a street sweeper multibody dynamics (MBD) model and verification by field tests
The chassis of a the RAVO 5 iSeries street sweeper has been a proven design that has remained relatively unchanged since the mid-60’s. However, due to increasing weight and size requirements, as well as possible changes to the driving mechanism, an overhaul of the chassis platform is needed. To develop a new (modular) chassis, which is suited for upcoming and future changes, a CAE-driven design approach is chosen, which is being performed by VIRO. When using computer-aided engineering (CAE), the chief problem is to define or estimate the acting loads and / or boundary conditions on a structure. In case such a structure is dynamically loaded, such a determination is further aggravated. Furthermore, if that structure is a chassis, a wide range of load cases and interconnected systems (e.g. tyres, suspension) effect the multifaceted loading behavior.
By utilizing multibody dynamics (MBD) and creating a MBD-model of the current street sweeper, a first step is taken towards developing a new (modular) chassis. The calculated loads and moments acting on the suspensions and chassis are quantified for e.g. several worst case scenarios, which allows for well-founded decisions in relation to the new design. Furthermore, these load conditions can be used as input for future topographic optimizations and / or stress analyses. An important part, when creating a CAE-model, i.e. in this case a MBD-model, is the validation of that model by experiments and /or analytic formulations. Consequently several calculated load cases have been tested in the field and in mutual cooperation. A subsequent verification shows that the measured accelerations correlate well with the calculated accelerations from the MBD-model.

Optimizing for Motorcycle Success - Improving Design Performance of Printed Composite Parts
MOTO-MAQLAB-UC3M was founded in 2010 by students at Carlos III University in Madrid, Spain, to develop a racing motorcycle for the international MotoStudent competition. MotoStudent is an international event held every two years at the MotorLand, Aragon circuit and welcomes university teams from all over the world. The MOTO-MAQLAB-UC3M team won awards in several categories of the fourth MotoStudent edition.
Inspired by their successful participation, the students wanted to further develop and improve their race bike designs to repeat or exceed these results. In order to improve their results, the MOTO-MAQLAB-UC3M team needed to reduce the mass in the cycle parts of the bike. Altair solutions enabled the MOTO-MAQLAB-UC3M team to approximate the ideal number of layers, their shape, order, and direction. Mass reduction of 30% was achieved while maintaining the original stiffness.

Improving the Shipbuilding Block Assembly Method: An Engineering Approach
Block construction is a modern shipbuilding method which involves the assembly of prefabricated modular sections. Cross-sections of the superstructure are pre-built in a shipyard, taken to the building dock, then hoisted into position and attached.
Block splitting and lifting schemes are largely devised after the ship design phase is completed, relying on empirical data and expertise to avoid costly and potentially dangerous failures during build-up. Advances in computer-aided engineering (CAE), however, now make it possible to plan ship build-up in the principal design phase, giving designers greater insights into block assembly process outcomes and reducing downstream risk through simulation.
