Description
The Intermittent Connection Model simulates a faulty connection by toggling the IsOpenCircuit flag of the Power Node Model attached to the same Physical Object or inherited class. The model is configured via the Intermittent Mean and Intermittent Standard Deviation to set the frequency of the Intermittent Error.
Example Use Cases
- Fault Simulation: Simulating real-world scenarios where power connections may experience intermittent failures due to vibration or thermal cycling.
- Reliability Testing: Testing system robustness against intermittent power issues to ensure critical systems can continue to function.
Module Implementation
The Intermittent Connection Model works by periodically toggling the Is Open Circuit flag of the Power Node Model that it is attached to. When Is Open Circuit is set to true, the power connection is broken, and no current can flow through the circuit. When set back to false, the connection is restored.
The timing of these connection interruptions is determined by a Gaussian (Normal) distribution with parameters:
Intermittent Mean: The average time (in seconds) between connection interruptionsIntermittent Standard Deviation: The standard deviation (in seconds) of the time between interruptions
For each simulation step, the model calculates whether an interruption should occur based on the configured distribution parameters. This creates a pattern of random connection failures that follow the specified statistical properties.
A Is Connected flag is available on the model to track if the Error Model has broken the connection.
Assumptions/Limitations
- The model assumes that the connection failures follow a normal distribution, which may not accurately represent all real-world failure modes.
