Designing Reliable Robots for Moon Exploration

Simulation plays a key role in developing robots to explore the Moon. Astrobotic Technology, Inc., Pittsburgh, Pennsylvania Equipment for space exploration is almost impossible to test on Earth. Testing is expensive and cannot replicate the conditions of launch, cruise, landing, and travel across a planetary surface. As space exploration shifts to the private sector, Astrobotic Technology, Inc. is taking the lead in delivering affordable robotic technology. The company uses ANSYS technology to stay competitive, virtually testing its lunar robots on time and under budget.

Designing Smaller Magnets for the Large Hadron Collider

CERN designs a smaller and more powerful superconducting accelerator magnet using ANSYS multiphysics tools. FEAC Engineering, Ioannina, Greece The European Organization for Nuclear Research (CERN) requires new magnets that are smaller than their predecessors to accommodate new instrumentation. Because of their size, these magnets need to generate a 24 percent stronger magnetic field and the structure must provide for near-zero deformation of the conductor. Even a small deformation could increase the electrical resistance and raise the temperature enough to cause the conductor to lose its superconducting state. Engineers addressed this challenge using ANSYS electromagnetic, thermal, and structural simulation tools. Coupling the multiphysics domains in the ANSYS® Workbench® environment allowed the team to optimize the design by simultaneously considering all of the physics.

Composite Sports Car Body Design

KTM Technologies quickly and reliably designs a composite sports car using ANSYS technology. KTM Technologies GmbH, Salzburg, Austria The use of composites is rapidly growing across many industries, fostering the need for new design, analysis, and optimization technologies. Every industry feels increasing pressure to launch breakthrough products that outperform competitors and meet market needs. For many design applications that require strong, yet lightweight materials, layered composites are ideal. Even so, faster, more frequent product introductions and new technologies cannot compromise ultimate product quality, reliability, and speed to market.

Simulation and Visualization of Elastodynamics in Time- Evolving Generalized Curvilinear Coordinates

Deforming grids and stresses can be visualized as the solution proceeds in time. Ames Research Center, Moffett Field, California This innovation unifies an earlier innovation and a new solution method based on finite differences to simulate structural dynamic phenomena over time-varying grids in generalized curvilinear coordinates. The methodology is based on physics-based first principles partial differential equations of elastodynamics in the space-time domain. It provides a powerful, yet simple methodology to compute structural dynamic variables of interest such as stresses over an entire grid mapped over or inside a given body of interest directly in the time domain. The grid can be allowed to deform in time as the solution evolves. The simulation (deforming grids and stresses) can be visualized as the solution proceeds in time; the simulation can be suspended at any point in time based on the visualization of the state of the system, and the simulation can be resumed/terminated altogether as the evolving solution proceeds within/outside the expectation bounds dictated by physics. The attractiveness of the innovation lies in the intuitiveness of the approach where the physical variables such as stresses and the displacements can be visualized directly in space and time as the simulation proceeds.

3D Finite Element Model of Magnetic Mirror and Nano Antenna

Simulations are considerably cheaper and faster than the fabrication process. Goddard Space Flight Center, Greenbelt, Maryland A 3D finite element mathematical model has been developed for representing a behavior of a magnetic mirror and nano antenna subject to polarized incident light. This model represents the fourth generation of magnetic mirror with the goal of suppressing the diffraction.
