World-class teams meticulously analyze the trajectory of each run, identifying deviations from the ideal path and implementing corrective measures in training and sled setup.
The effectiveness of trajectory optimization is often evident in split-time comparisons. For example, if a team consistently achieves slower times through a specific corner, analysis of their trajectory using video and sensor data may reveal that they are entering the corner too wide, resulting in a longer path and a less-than-optimal exit angle. By adjusting their entry point and steering technique, they can shorten the distance traveled and improve their exit speed, leading to a faster overall time. This type of analysis often involves sophisticated computer simulations that model the dynamics of the sled and the forces acting upon it, allowing teams to predict the optimal trajectory for various track conditions and sled setups. During the 2018 Winter Olympics, the German team employed trajectory analysis to improve their cornering lines, resulting in noticeable gains in speed through several key sections of the track.
In conclusion, trajectory optimization is indispensable to a comprehensive understanding of a World Championship bobsleigh run. It connects directly to the reduction of overall time by ensuring the most efficient use of momentum. This understanding supports focused improvements in both athlete technique and sled configuration.
