Simulating the Model

Using Adams Durability you can access test data in two formats: RPC III Format or DAC Format. First you must validate your model, then you can perform what-if simulations.

Performing Model Validation

When simulating your model to compare it to physical test data, you need to follow the general steps listed below.

To validate a model:

1. Input the forces or motions using spline data (see Referencing Test Data). Make sure you use the INTERP function for the RPC III or DAC files (see Applying Test Data).
2. Set up requests that correspond to the physical data channels (learn how).
3. Set up Adams View to output the results in the format you prefer (learn how).
4. When you’re ready to simulate the model, make sure the End Time and number of Steps in the Simulation container correspond to the physical test data that you are using for model validation.
5. When the simulation completes, make sure you reset the model.
6. Import the virtual and physical test data (see Importing Test Data).
7. Use Adams PostProcessor to compare the virtual data to the physical test data (see Plotting Data).
8. Modify your model and repeat these steps as necessary until you’re satisfied that the virtual test data correlates well with the physical test data.

Performing Durability What-If Simulations

Once you’ve validated your model, you’re ready to make modifications to determine their impact on system response or component durability. To obtain data that lets you determine system sensitivity to various design changes, you should follow the general steps listed below.

To perform durability what-if simulations:

1. Make simple model modifications, so that you can easily determine model sensitivity to each change.
2. Use the same input forces or motions that you used in the initial model validation.
3. Use the same requests that correspond to the physical data channels (learn how).
4. Set up Adams View to output the results in the format that you prefer (learn how).
5. When you’re ready to simulate the model, make sure the End Time and number of Steps in the Simulation container correspond to the physical test data that you used for model validation.
6. When the simulation completes, make sure you reset the model.
7. Import the new virtual and physical test data (see Importing Test Data).
8. Use Adams PostProcessor to compare the virtual data to the physical test data (see Plotting Data). If system response looks better, you can input these data to durability analysis programs and compare them to the results you obtained from the physical test data. Otherwise, make further model modifications and simulate again.
