Identify suitable accelerometer for an application
Procedure
Prerequisite :
- Read and understand all instructions and questions provided
- Answer all questions and click on the "Submit Test" button
- Upon successful completion, click on the "Next Level" button which will appear in place of the "Submit" button
Simulator :
Configuration :
- Select Accelerometer Type: Choose the type of accelerometer required for the experiment
- Select Mass: Choose the desired mass in kilograms (kg) from the available options
- Select Mass Displacement: Choose the displacement value in centimeters (cm)
- Select Spring Constant: Choose the spring constant in Newton per meter (N/m)
- Click the "CHECK CONFIGURATION" button to verify the selected inputs
Mimic :
- Starting the Simulation: Click on the green "START" button
- Observe the frequency graph that appears on the screen
- Calculate the natural frequency (in radians per second, rad/s) using the formula:
FORMULA : f = √(k/m)
- Enter the calculated value in the provided textbox and click on the "SUBMIT" button
- Convert the natural frequency to frequency in Hertz (Hz) using the formula:
FORMULA : f(Hz) = ω(rad/s) / 2π
- Enter this value in the respective textbox and click on "SUBMIT"
- Calculate the acceleration based on the readings obtained
FORMULA : Maximum Acceleration = (Natural Frequency)² * Mass Displacement
- Enter the calculated acceleration value in the textbox and click on "SUBMIT"
- Click on the red "STOP" button to end the current simulation
- Repeat the above steps under Configuration and Mimic a minimum of 5 times to obtain consistent readings
Calibration :
- After taking 5 readings, refer to the Calibration Graph displayed below the reading table
- Use the graph to adjust and verify the accuracy of your readings
- Now select another type of accelerometer
NOTE: Follow steps of Configuration, Mimic for another type of Accelerometer
