What does the snow in the Winter Olympics stand for?

All mankind are linked together through the Winter Olympics, leaving a deep impression on the whole world. It also contains the wishes and ideas of * * *. ? The opening ceremony of the Winter Olympics was screened, which made many netizens shout "This is the romance of China people". What is China's aesthetics, what is China's feelings, and what kind of art is the most powerful.

Talking about this creation, Song Chen thinks that taking the contemporary expression of traditional spirit as the core, he should carry out artistic innovation on the basis of inheriting China's traditional culture, show the simple, ethereal and romantic ice and snow aesthetics belonging to China people, and convey the idea of Beijing 2022 Winter Olympics facing the future together.

Design Concept of Snowflakes in Winter Olympics

The main torch of Beijing Winter Olympics was lit in a dazzling "big snowflake". This snowflake is not afraid of wind. Because of the efforts of a group of "wind knights" in the wind tunnel laboratory of Beijing Jiaotong University, the "wind" here has disappeared.

In July, 20021year, Li Bo, the head of the wind tunnel laboratory of Beijing Jiaotong University, was assigned to provide a feasibility study for the "Big Snowflake" ignition scheme. He introduced that the original plan was to suspend the "big snowflake" and tilt it to the ground. After inserting the torch, the torchbearer continues to lift the "big snowflake" to complete the lift-off and rotation.

In order to realize the function of the ignition ceremony under the premise of safety and stability, it is necessary to know the actual wind speed of the venue that day. Li Bo immediately set up a research team to design the scheme, and evaluated the local wind climate of the Bird's Nest during the opening ceremony of the Winter Olympics based on a large number of historical data accumulated by the perennial observation of wind speed in the central city of Beijing.

The team soon found that due to the influence of the Bird's Nest building, the wind speed conditions in the rising area of "Big Snowflake" were different from the local wind climate. To this end, they also made a scaled model of the Bird's Nest for wind tunnel test, and determined the probability model of the wind speed of the "big snowflake" at the opening ceremony.

New problems followed. The shape of the "big snowflake" is very complicated, and it has to be turned, lifted and rotated during the opening ceremony. Only by making a high-fidelity scale model can we accurately measure the wind load on the "big snowflake" in different States.

The heavy snow is composed of olive branches and small snowflakes, and the overall structure is hollow. The traditional method of establishing wind tunnel test model is definitely not feasible. Li Bo said it can only be printed in 3D. After continuous attempts, the team finally found the most suitable aluminum alloy material and made a high-fidelity scale model, which amazed the main torch design team.
