    Area of Science:

    • Engineering
    • Mechanical Design

    Background:

    • Flexible arms are crucial in various engineering applications.
    • Current fixation methods for terminal nipples can lead to cable avulsion under tension.
    • This limitation affects the reliability and operational capacity of flexible arms.

    Purpose of the Study:

    • To describe a simple modification for attaching terminal nipples to the central cable of an engineer's flexible arm.
    • To enhance the reliability and tension tolerance of flexible arms.

    Main Methods:

    • A modification to the attachment of terminal nipples to the central cable was developed.
    • The modified attachment was tested for its ability to withstand greater tension compared to conventional methods.

    Main Results:

    • The modified attachment ensures the central cable breaks before the terminal nipples are avulsed.
    • Greater tension can be applied to the flexible arm using the new fixation method.
    • The increased rigidity resulting from the modification significantly improves the reliability of the flexible arm.

    Conclusions:

    • The described modification offers a simple yet effective solution to improve flexible arm performance.
    • This enhancement increases operational safety and extends the service life of engineering flexible arms.
