Abstract
Methods and apparatus for evaluating vibration resistance of a component of a fluid control valve are disclosed herein. An example method disclosed herein includes selecting a component of a fluid control valve and positioning a sensor relative to the selected component. The method also includes mechanically exciting the selected component, determining a resonant frequency of the selected component, and taking corrective action based on the resonant frequency of the selected component.

A method comprising:
- selecting a component of a fluid control valve;
- positioning a sensor relative to the selected component;
- mechanically exciting the selected component;
- determining a resonant frequency of the selected component;
- comparing the resonant frequency of the selected component to a predetermined resonant frequency of the fluid control valve;
- and
- reconfiguring the selected component to have a relatively higher resonant frequency when the resonant frequency of the selected component is within a threshold of the predetermined resonant frequency of the fluid control valve.

A method comprising:
- selecting a component of a fluid control valve, wherein the selected component includes a tubing run;
- positioning a sensor relative to the selected component;
- mechanically exciting the selected component;
- determining a resonant frequency of the selected component;
- taking corrective action based on the resonant frequency of the selected component by reconfiguring the selected component to have a relatively higher resonant frequency by bending the tubing to have at least two bends.

A method comprising:
- selecting a tubing run coupled to an actuator assembly of a fluid control valve;
- exciting the selected tubing run;
- monitoring a time-varying movement of the selected tubing run when excited;
- measuring an amplitude of the time-varying movement of the selected tubing run;
- determining a resonant frequency based on the amplitude of the time-varying movement of the selected tubing run;
- comparing the resonant frequency of the time-varying movement to a predetermined resonant frequency of the actuator assembly;
- and
- adjusting the selected tubing run by bending a portion of the selected tubing run when the resonant frequency of the time-varying movement is within a threshold of the predetermined resonant frequency of the actuator assembly.
