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.

Efficient Engineering Based Modeling of Layered Composite Structures

This presentation is by Program Manager Rob Jopson. It’s a given that the simulation models we build are intended to capture and predict physical behavior, the data used to create them is not always representative of the manufacturing process used to build the physical part. For layered composite parts in particular, this mismatch can cause significant overhead in managing the simulation data as the model is created and evolves. To solve this problem, Altair’s ply-based modeling methodology strives to maintain a 1:1 relationship between the simulation data and the manufacturing process, independent of solver. The latest developments of this methodology will be presented as a workflow in the new Composite Browser, available in HyperWorks. The recording is about 18 minutes long and was originally presented at the 2020 ATCx Composites.
