Interconnected rigid bodies
researchgate.net
- Linkage mechanisms consist of interconnected rigid bodies, often referred to as links, joined together by movable joints. These mechanisms convert input motion or force into the desired output motion or force, enabling machines and devices to perform complex tasks with remarkable efficiency and precision.

Links. Links are the rigid bodies that make up a kinematic chain. Links can be any shape or size, but they must be rigid enough to withstand the forces that are applied to them. Nodes. Nodes are the points where two or more links are connected. Nodes can be simple, such as a pin joint, or they can be complex, such as a cam and follower joint ...
A mechanical linkage is an assembly of systems connected so as to manage forces and movement. The movement of a body, or link, is studied using geometry so the link is considered to be rigid. [1] The connections between links are modeled as providing ideal movement, pure rotation or sliding for example, and are called
Simple linkages change the direction of motion and the amount of force. Reverse motion linkages change the direction of input so that the output goes the opposite way. A fixed....

A flexible link, as the name suggests, is a link that can bend or deform without significantly affecting motion transmission. It is often used to allow flexibility in a mechanical system.
Flexible links are designed to flex or bend when subjected to forces or movement.They accommodate variations in alignment and absorb shocks or vibrations.Their flexibility is advantageous when dealing with irregular or dynamic motion.Flexibility allows for accommodating misalignments.Effective in reducing shock and vibration.Widely used in applications requiring dynamic movement, such as robotics and conveyor systems.May introduce some degree of imprecision due to flexing.Not suitable for applications requiring strict precision and rigidity.Conveyor belts, flexible couplings, and articulated robotic arms often incorporate flexible links to allow for smooth and adaptive movement.
A rigid link, in contrast to a flexible one, does not undergo deformation during motion transmission. It remains stiff and unyielding, preserving the integrity of the mechanical system.
Rigid links maintain their shape and length under loads.They provide precise and consistent motion transmission.Rigid links are crucial when precision and rigidity are required.Ensures accurate and predictable motion.Suitable for applications demanding high precision and minimal flexing.Common in machinery like engines, gears, and mechanical linkages.Limited adaptability to misalignments or dynamic motion.Vulnerable to shock and vibration, which may lead to wear or damage.Internal combustion engines, gear systems, and mechanical assemblies in manufacturing machines rely on rigid links for precise and stable motion transmission.
A link has two hinges, one at each end. It permits movement in all direction, except in a direction parallel to its longitudinal axis, which passes through the two hinges. In other words, the reaction force of a link is in the direction of the link, along its longitudinal axis.
Linkages - mechanical assemblies consisting of rods and links which are connected by movable joints are designed to transfer motion and forces in a controlled manner. Supporting different types of movements, including linear, rotational, and oscillatory, linkages are used widely in many applications, such as automotive systems (for instance ...
