SkyCiv Science Olympiad 2023 App de competição

Design and test your Tower structures, usando o aplicativo da Olimpíada de Ciências

SkyCiv has partnered with Science Olympiad to help digitize the Science Olympiad competition for the 2023-24 estação! The app sits inside SkyCiv Structural 3D to simulate the competition testing.

The SkyCiv Science Olympiad App will auto-analyze and test your structure based on the competition criteria. Instead of physically building the model and testing it under a load of a bucket of sand, the App will apply the load gradually and test it based on Finite Element Analysis. Key results are then displayed, with some insight into why the structure is failing. The app will also test the rules and guidelines of the competition, including the load distance, structure width, material usage, e mais (Veja abaixo).

Começando

After signing up for a Science Olympiad Account (or SkyCiv Student Account), login and visit your account settings: https://platform.skyciv.com/account/settings Under Add-ons and Integrations, you should see a Olimpíada da Ciência aplicativo. Switch that on and click Save Settings. Uma vez feito isso, Visita SkyCiv Structural 3D and you should see the Science Olympiad app under Add-ons na barra de navegação superior:

Clicking this will launch the App and allow you to start testing your model.

Building Requirements

Each individual event, concorrência, ou a divisão pode ter seu próprio conjunto de requisitos de construção. Contudo, existem alguns requisitos de construção consistentes para o aplicativo, that should be met regardless of what level of competition you’re in.

• The number of Area Loads the Tower must support is two for Regionals, three for State, and four for Nationals.
• One Area Load must have nodes at (x = ±2.5 cm, y = 50 cm, z = ±2.5 cm) for Division B and (x =±2.5 cm, y = 60.0 cm, z = ± 2.5 cm) for Division C.
• The other Area Load(s) will have nodes at coordinates specified by the Event Supervisor in the range (-20 cm ≤ x ≤ 20 cm, 12.5 ≤ y ≤ 37.5 cm, z = ±2.5 cm) for Division B and (-20 cm ≤ x ≤ 20 cm, 15.0 ≤ y ≤ 45.0 cm, z = ±2.5 cm) for Division C.
• The y-coordinates for all nodes in an Area Load must be the same.
• Your area load should be a Essas cargas distribuídas equivalentes são o que é usado para a análise do membro -60 kPa force over a 5x5cm square. Area load nodes (Cargas Distribuídas Normais e cargas distribuídas equivalentes são diferenciadas por suas cores vermelha e verde entrada) should be entered in a clockwise or anti-clockwise direction. Here is an example of a correctly applied area load:

Além disso, note the variance is 0.00% this is also required for the successful solve of your structure.

Building Direction

You will also need to build your structure in the Y-direction. Novamente, here is an example of a correctly built structure:

Carga Pontual

Each of the four nodes of the Area Load, must have a Point Load in the positive-z direction with magnitude 5–25 N, the same magnitude for all Point Loads.

Apoia

The Tower must be supported using exactly four supports placed in the plane of the Test Base (y = 0); two must be “Horizontal Rollers in X” with x-coordinates ≥ 20 cm and two must be “3D Pin Supports” with x-coordinates ≤ -20 cm, without restrictions on z-coordinates.

Seções

The cross-section of individual members must be rectangular with minimum cross-sectional dimensions as specified in SkyCiv of 1.5 mm by 1.5

Results and Scoring

Main Results

The app will run through about 100 iterations to calculate the load at which the structure fails (if in fact, it fails). During this process, it will calculate the following results:

• Max Stress: this is the stress that your members are undergoing under the peak load. If your structure is failing due to stress (stress exceeding 7MPa) then this result will hover under that stress limit.
• Peso da Estrutura: the weight of the structure. This value is used as the denominator in the calculation of the performance score. So the lower this value, the higher your score.
• Capacidade da Estrutura: how much weight your structure held (excludes self-weight).
• Pontuação de desempenho:
• Towers that have a Load Supported of 15,000 g will earn a Bonus of 5,000
• Score = Load Score (g)/Mass of Tower (g).

Criteria Checks

In the background, the app will be checking the following:

• Materials used were one of 3 allowable Balsa Wood grades
• Plus more

These results will be submitted with your overall score to ensure the rules and guidelines of the competition are met.

Modo de competição

On your designated event day, users will toggle on the Modo de competição no canto superior direito. Importante: Toggling on this switch will delete your model, remove some of the functionality in S3D and limit the number of solves for 48 horas. Please do not toggle this on unless it is your competition/event day. The blue Submit Score button will also become available where you can submit your final score via the below form.
