Analyzing Composites for Housing Electronic Circuits in Satellites

Scientific, observation and reconnaissance missions are often performed by low-orbiting micro satellites. These systems are much smaller and more compact than larger telecommunications satellites, so space is severely limited and heat is more difficult to dissipate from closely packed electronic components. Traditionally, satellite electronics housings are made of aluminum. This material is lightweight, has adequate heat dissipation, and provides good protection against ambient spatial radiation. In one recent study, the European Space Agency (ESA) investigated the feasibility of fabricating these housings of composites to determine if this type of material systems could provide the same heat dissipation as aluminum but with less mass.

Simulation Evaluates Transmission Loss and Pressure Drop of a Tractor Mu ? er, Saving Time and Cost

A mu?  er in the exhaust system of a tractor de-creases the sound output while increasing the back-pressure of the ? owing exhaust gases. Transmission loss (TL) refers to the reduction in acoustic noise provided by a mu?  er, and needs to be maximized (a higher TL means a quieter tractor). The engine must work against the backpressure; the higher the backpressure the less power delivered to the power train, so backpressure must be minimized.

Simulation of Wind Turbine Sites Increases Power Yield and Reduces Risk

Wind energy is a rapidly growing source of electricity. When developing wind farms, turbine siting assessment is critical to maximizing the energy yield and economics at a given location.Detailed understanding of how the prevailing wind conditions interact with the local ter-rain and potential wind turbine installations is an essential part of the process of developing onshore wind farms.

Simulation Cuts Yearly Material Costs by $1.2 Million -Whirlpool CorporaWhirlpool Corporattion

Global competition in the appliance industry is placing ever-increasing pressure on manufacturers to decrease costs while maintaining high quality.When Whirlpool Corporation looked to cut costs associated with producing a three-year-old, 450-liter double-door refrigerator, it needed to continue to meet the specific cabinet deflection and door drop limits of its current design; it also needed to maintain adequate cabinet stiffness.By using ANSYS Mechanical software and Six Sigma tools, analysts are given the ability to develop complex finite element cabinet models calibrated with real data, enabling the optimization of first-round physical prototypes. This procedure reduces development time and cost while meeting market requirements.”

Fluid-structure interaction simulations prove ability of solar artifacts to withstand wind gusts

With India’s large and growing population, the challenge of generating enough power to sup-ply the peoples’ needs is great. Increasing the number of renewable energy sources can solve this problem. Aesthetically pleasing designs of solar cells (called “solar artifacts”) in the form of umbrellas (Attapatram) or trees (Surya Banaspati) can be placed in commercial or public spaces while maintaining the space underneath for productive or recreational uses.

Timing a Series of Explosions for Maximum Impact with ANSYS AUTODYN

In today’s mining operations, rock blasting is about precision control of tremendous amounts of energy. The key is a series of well-planned explosive detonations in which rows of explo-sive-filled blast holes are set off with electronic detonators in a precise-delay timing sequence measured with millisecond accuracy. If timed just right, shock waves reinforce and amplify one another to produce maximum fragmentation and movement of rock, ore, coal and other materials.

Flow Modeling Helps to Prove Hurricane Damage Caused by Wind, Not Water

A traditional approach called for the simple application of equations relating force and wind speed; however, these would not have in-cluded information about the building shape nor accounted for the air ? owing through open doors inside the building. TRC determined that a more accurate simulation of the pressure forces on the building would provide more persuasive evidence that the damage was wind related, resulting in payment of the claim.

ANSYS Mechanical and Scripting Evaluate Cumulative Damage in Subsea Oil and Gas Equipment in Compliance with ASME BPVC VIII Division 3

Design of subsea oil and gas equipment has moved to high pressure and high temperature domains. With pressures beyond 15,000 psi and temperatures beyond 350 F, designs have to be qualified per ASME BPVC VIII, Division 3, which requires the cumulative damage on the equipment to be below 1. Local damage check evaluates the equipment’s design against local strain rupture.

Increasing Productivity Through Staff Efficiency

By adopting ACT driven multiphysics simulation, Oticon was able to democratize the use of simulation without compromising with the reliability of results.   More than 75% of simulations traditionally done  by experts can now be delegated to non-expert simulation users. Specifically, Oticon freed the simulation experts to model the full system, the complete hearing aid, rather than just some of its key components.  This translates  in significantly better performance leading to more competitive products and eventually will eradicate costly and time consuming  late stage design fixes.
