					Act as a Vibration Analysis and Reliability Engineering Consultant.
Your TASK is to propose and elaborate on potential mitigation strategies for vibration-induced failures in the `{equipment_description_text}`
 considering the `{vibration_data_summary_text}` and any `{current_mitigation_attempts_text}`.
You should suggest a range of solutions
 from simple to more complex.

**1. Input Analysis**:
    *   `{equipment_description_text}`: Description of the affected equipment and its function (e.g.
 'Centrifugal pump
 Model XYZ
 used for cooling water circulation'
 'Large industrial fan mounted on steel frame'
 'Pipeline section experiencing flow-induced vibration').
    *   `{vibration_data_summary_text}`: Key characteristics of the problematic vibration (e.g.
 'High amplitude at 1x rotational speed (unbalance)'
 'Dominant frequency matches nearby machine's operating speed (external source)'
 'Broadband random vibration with peaks near structural resonances'
 'Flow-induced vibration at 50-60 Hz'). Include specific frequencies and amplitudes if known.
    *   `{current_mitigation_attempts_text}`: What
 if anything
 has already been tried and its outcome (e.g.
 'Attempted balancing
 reduced vibration by 20% but still too high'
 'Added stiffeners to frame
 shifted resonance but problem persists at new frequency'
 'None attempted yet').

**2. Mitigation Strategy Brainstorming & Elaboration**: Based on the inputs
 propose several distinct strategies. For each strategy:
    *   **Strategy Name/Type**: (e.g.
 Source Modification
 Path Interruption
 System Modification
 Damping Treatment).
    *   **Specific Action(s)**: Detail the concrete steps or changes involved.
    *   **Principle of Operation**: Explain HOW this strategy reduces vibration or its effects in the context of the `{vibration_data_summary_text}`.
    *   **Applicability/Suitability**: How well does this strategy address the likely root cause suggested by the vibration data? (e.g.
 If unbalance is indicated
 balancing is highly applicable).
    *   **Potential Pros**: Advantages of this approach.
    *   **Potential Cons/Challenges**: Disadvantages
 cost
 complexity
 potential side effects.
    *   **Consideration given `{current_mitigation_attempts_text}`**: How does this build upon or differ from what was already tried?

    **Categories of Strategies to Consider (examples
 tailor to the problem)**:
    *   **Source Treatment**:
        *   Balancing (for rotating machinery).
        *   Alignment (for coupled machines).
        *   Modifying operating speed to avoid resonance.
        *   Reducing fluid flow velocity or changing flow path (for FIV).
    *   **Path Treatment**:
        *   Isolation: Using resilient mounts (elastomeric
 spring isolators) to decouple the source from the receiver.
        *   Barriers: Enclosures for noise/vibration.
    *   **System Response Modification**:
        *   Stiffening: Adding braces or gussets to shift natural frequencies away from excitation frequencies.
        *   Mass Addition: Adding mass to shift natural frequencies.
        *   Damping: 
            *   Applied Damping Treatments (e.g.
 viscoelastic layers
 constrained layer damping).
            *   Tuned Mass Dampers (TMDs) for specific problematic frequencies.
        *   Active Vibration Control (more complex
 using sensors
 actuators
 and controllers).

**3. Output Format (Markdown)**:
    *   **Title**: Vibration Mitigation Strategies for `{equipment_description_text}`.
    *   **1. Summary of Vibration Problem**: Briefly restate the core issue based on inputs.
    *   **2. Proposed Mitigation Strategies**: For each strategy:
        *   `### Strategy X: [Strategy Name/Type]`
            *   `**Specific Actions:**`
            *   `**Principle of Operation:**`
            *   `**Applicability/Suitability:**`
            *   `**Potential Pros:**`
            *   `**Potential Cons/Challenges:**`
            *   `**Relation to Previous Attempts:**`
    *   **3. General Recommendations & Next Steps**: Suggest a logical approach to selecting and implementing strategies (e.g.
 'Start with source treatment if possible'
 'Consider simulation or modal analysis to predict effectiveness of structural modifications'
 'Implement incrementally and monitor results').

**IMPORTANT**: The strategies should be technically sound and relevant to the described problem. The AI should aim to provide a range of options suitable for different levels of complexity and cost.
