Sports Industry Webcast Series: The Contribution of Simulation to 21st-Century Sport Engineering

   

Sports professionals, coaches and amateur participants always explore ways to boost performance, ensure comfort and minimize the risk of injury. At the same time, sporting equipment manufacturers must investigate technologies to innovate faster and maximize the reliability of products that sometimes face extremely challenging conditions.

Engineering has long been one of the tools used, but, for the past few years, the sport engineering community has been paying closer attention to engineering simulation. Through computer-based modeling, it is possible to determine and understand how influential parameters impact athletic performance, or minimize or amplify injuries.

First Computer Simulations and Wind Tunnel Tests of Full Cycling Pelotons Give Breakthrough Insights

For the first time, Eindhoven University of Technology and KU Leuven have simulated the aerodynamics of a full peloton with Ansys Computational Fluid Dynamics on CRAY supercomputers. This world-record CFD simulation provides a series of brand new insights into the distribution of air resistance for cyclists inside the peloton. It shows that almost all current mathematical strategic models for breakaways in cycling are based on incorrect assumptions.

View this on-demand webinar to:

  • See the power of the largest CFD modeling ever done in sports
  • Learn about the challenges of meshing such an extreme geometry properly
  • Understand the large impact of cycling aerodynamics on elite athletes
  • Get valuable insight into how you can bike more efficiently during your next bicycle tour

Learning From Cycling Aerodynamics to Improve Speed Skating: Similarities and Differences

It is not obvious that the sports of competitive cycling and speedskating have anything in common, until you look at the aerodynamics of cyclists and skaters. In each case, the lead athlete does more work in cutting through the air currents, while trailing athletes can experience some negative or positive effects of the leader’s wake. Previous CFD studies have demonstrated the various effects of “drafting” off a lead cyclist in the Tour de France and other competitions.

In this webinar, we will apply the lessons learned from cycling to speedskating through Ansys CFD studies. Join us to discover unexpected aerodynamic interactions between skaters competing against each other. We will also investigate the effects of specific skinsuit designs worn by the skaters to reduce air resistance, using both CFD and wind tunnel tests. Learn how CFD simulation, validated by experiments, can reveal formerly unknown aerodynamic effects and contribute to improved suit designs.

Snowboarding Wrist Protection for Beginners to Elite Athletes

The forearm and wrist account for around 35 to 45 percent of all injuries in snowboarding. Wrist protectors can prevent such injuries by limiting wrist hyperextension and attenuating impact forces. There are many wrist protector concepts, but little consensus as to which designs offer the most protection. While experimental protocols have been developed for characterizing existing wrist protectors, they are limited when it comes to predicting the influence of design changes. Finite element analysis (FEA) can be applied to further our understanding of wrist protector design concepts, without the need to build prototypes.

Attend this webinar to learn more about FEA models used for predicting the protective levels of snowboard wrist protectors. A candidate wrist protector has been selected, its parts replicated in a computer-aided design package and its constituent materials identified. Discover the range of FEA models that are being developed in Ansys LS DYNA, from a single splint or foam pad to a complete wrist protector fitted to a surrogate for simulating surface impact. The models will be compared against experimental data to ensure accuracy.

Which cyclist’s hill descent position is really superior? Froome, Pantani, Nibali or Sagan? New Results!

By Professor Bert Blocken, Eindhoven University of Technology (TU/e) in the Netherlands and KU Leuven and the University of Liege in Belgium

Different professional cyclists use very different hill descent positions, and there is no consensus in the peloton on which position is truly superior. Most cyclists did not test different positions in wind tunnels to find which one would give them the greatest aerodynamic advantage. This valuable information could be the difference between winning and losing a major cycling event.

Join us for this webinar in which we will discuss which cyclist’s hill descent position is aerodynamically superior by comparing 14 positions used by professional riders in the past. Using two different and independently applied research methods — wind-tunnel testing and CFD simulations (which yield the same conclusions) — we have arrived at the answer scientifically. Learn which positions are superior from safety and power generation viewpoints. Here’s a tantalizing hint: The infamous “Froome” position during the Peyresourde descent of Stage 8 of the 2016 Tour de France is 8 percent slower, provides unequal distribution of body weight over both wheels and reduces power generation. Attend this webinar to discover new results that contradict those announced previously via LinkedIn.

Reducing the Risk of Concussion Through Personalized Helmet Design

By Ross Cotton, Simpleware Synopsys; Bence Gerber and Chris Quan, Ansys

Concussions and other head injuries are significant issues in modern sports involving head impact. The long-term viability of these sports is being called into question because of the severity of the brain injuries that affect players long after their careers have ended. A highly realistic 3-D head model has been developed by Simpleware Ltd. from MRI data using novel segmentation and image-based meshing techniques. Ansys Mechanical simulations are being used with this head model to evaluate and optimize the performance of next-generation protective head gear.


Attend this webinar to investigate the potential of image-based 3-D modeling from scan data (such as CT and MRI) for better understanding of damage to the brain and the performance of protective headgear. By analyzing the shockwaves generated in the model of the head and a football helmet using Ansys Mechanical, engineers are learning how to optimize helmet designs, including the materials used to manufacture them, so they can absorb more of the shock that would normally reach the brain and reduce sudden stress amplification from shock reflection.
