Engineers need an integrated Simulation toolset to develop and optimise safe autonomous systems

Learn how ANSYS’ integrated toolset can overcome the complex technical challenges in the development of fully autonomous systems: helping to deliver safe and reliable systems that operate efficiently in complex, changing environments. As engineers, we intuitively understand that comprehensive simulation is the only way to thoroughly consider all real-world scenarios for these systems in a fast and cost-effective way.

Crash Simulation of the Waterfall Train Disaster

On 31 January 2003, a four car Tangara passenger train G7 on run from Sydney Central railway station to Port Kembla derailed about 2 kilometres south of Waterfall railway station. The train driver and six passengers were killed and many passengers suffered serious injuries. Following the accident considerable media coverage was given to speculation concerning its cause. Numerous causes were canvassed and discussed in numerous media reports. The possible causes mentioned ranged far and wide. They included: problems with the track, excessive speed, poor maintenance, inadequate safety management, alleged prior mechanical problems which allegedly caused a surge in traction power, modification to a faster AC traction motor, motor power failure, brake failure, human error, the health of the train driver, mechanical failure, power surge when...

From fatigue failure to EMI/EMC: the vast range of FEA and Emag applications in the Rail industry

ANSYS: Extracting the parasitic effects from a 3D package geometry
As your train rumbles along during your morning commute, you are more likely to be hooked to your smartphone than thinking of all the types of simulations that have gone into making your journey safer and provided a more comfortable ride (though unfortunately they still can’t help with that odour coming from one of your riding companions!). Engineers working in the rail industry will recognise the expanding use cases of FE and Emag simulations that are now undertaken on a routine basis in the development of new systems: from the design of individual components, sensors and actuators, to fatigue of structural members and critical components such as wheels, axles, bogies; through to the creation and certification of safety-critical software code: engineering simulation tools are now...

Dramatic Accelerations in the Performance of Antenna Placement and Co-site Interference Simulations with NVIDIA GPUs

Figure 1 - Radiation pattern of a ship calculated in ANSYS HFSS SBR+
After talking to design engineers who are responsible for both Antenna Placement and Co-site Interference simulations, we have heard that they typically desire results to be available in less than 10 minutes in order for them to effectively test all the different configurations required on a real-world project. If the simulation time grows beyond 10 minutes, then they consider that the number of design scenarios which can be analysed in a given working day becomes detrimental to their design process. In the past, this has been problematic for companies wanting to adopt simulation technology as antenna placement type problems will typically have enormous domain sizes and the types of geometry involved can rapidly escalate the difficulty of analysis. The first example presented here involves the...

Addressing the complex design challenges of composite parts using ANSYS Composite PrepPost (ACP)

Static Structural analysis results in ANSYS
It is well known that, compared to traditional materials, the fabrication of structures using composite materials offers clear benefits when designing high-performance products that require extreme strength and stiffness, combined with lower weight. However, the use of composite materials also presents additional challenges, as their mechanical properties are heavily influenced by loading direction and their brittle nature makes fracture a very serious possibility for poorly designed components. The ANSYS Composite PrepPost (ACP) suite has been specially designed to address these unique complexities of composite materials and aid engineers in designing high performance and safe components. This blog will follow the design and analysis of a composite wheel hub commonly used in high performance consumer and race cars. The fabrication of composite structures is based on...

Moving towards a Comprehensive Virtual PCB Testing Platform

ANSYS Simulation results for Printed Circuit Boards (PCBs)

Trends such as such as Industry 4.0, the Internet of Things (IoT), drones, smart home technology and autonomous vehicles are continuing to push PCB technology to its limits. Electronics engineers are now needing to focus on more than just the electromagnetics aspects of PCB design, and are increasingly concerned about power consumption, thermal & vibration issues linked to reliability concerns in harsh environments.

Efficient Multiphysics Simulation with ANSYS AIM

Whether you’re a designer, analyst, or expert in your field, ANSYS Integrated Multiphysics (or ANSYS AIM as we like to call it) can provide you and your company with an out-of-the box, all round tool for either single or multiphysics simulations. ANSYS AIM represents the culmination of developments in technology, computational power and user accessibility, meaning that the ability to run accurate CFD, FEA, or Electromagnetic simulations is now available to every engineer. AIM has been developed to be accessible, exciting, and most importantly useable to the everyday engineer, regardless of their experience level. AIM is seeing use around the world in companies that are looking to move from a limited single-physics approach and who are now looking to add realism by including multiple physics within…

Introducing the LEAP Academic Portal

LEAP Australia Design to Win at Monash University

For over 20 years, LEAP Australia has successfully supported the use of CAE software within the engineering and design community across Australia and New Zealand.  LEAP’s broad customer base has included over 2000 companies, from some of the world’s large OEMs through to SMEs and startups, and ranging across industries from traditional high-tech leaders such as Aerospace and Automotive through to leaders in fields as diverse as Energy, Mining and Biomedical. Regardless of the customer, we have identified a constant theme: demand for job-ready graduate engineers who are skilled in CAE software. Many years ago, LEAP committed to fostering greater knowledge and understanding of CAE in academia, by firstly partnering with all leading universities in our region, and also by providing sponsorship to many student…
