  • Linkage (mechanical) Wikipedia

    Jansen's linkage is an eight-bar leg mechanism that was invented by kinetic sculptor Theo Jansen. Klann linkage is a six-bar linkage that forms a Leg mechanism; Toggle mechanisms are four-bar linkages that are dimensioned so that they can fold and lock. The toggle positions are determined by the colinearity of two of the moving links.

  • Help needed please Toggle mechanism force calculations

    9/09/2014· Hi, I've searched everywhere trying to work out how to calculate the spreading force of a simple toggle mechanism. I have a two equal length arms that are hinged together. One end is fixed on a pivot pin and the other can slide along a flat plane but is resisted by a fixed stop. The hinged arms are not quite in line and aligning them would increase their overall length.

    Pin Connections and Two Force MembersMechanics of Toggle ClampsOver-ClampIt all starts with the humble pin connection, which prevents movement in the x or y direction, but allows rotation. Since rotation is allowed, no moment can be transmitted around the pin connection. An applied moment would simply cause the part to rotate, rather than transmitting across the link.If a link has pin connections on both ends, an interesting thing happens. Any force at one end that is not directly along the line betweeSee more on engineeringclicks

    The First Mechanism: The Lever is a 2-bar Linkage The simplest mechanism, and perhaps the first, is a lever and a ful-crum. The lever is a link, the fulcrum a joint, and the ground is also a link. Together they form a 2-bar linkage. These simple elements (a tree branch and a rock) with a force (Og) can create huge forces to do useful work. Once

  • Force and Torque Margins for Complex Mechanical Systems

    definition of force margin relates to the ratio between the driving forces and the resisting loads. For example, if the driving force is twice the resisting load, the force margin is 100 percent. The calculation of force and torque margins is relatively straightforward for a simple mechanism such as a spring-loaded hinge. However, for complex
