Appropriate Analysis of the Four-Bar Linkage

The configuration of a system of rigid links connected by ideal joints is defined by a set of configuration parameters, such as the angles around a revolute joint and the slides along prismatic joints measured between adjacent links. The geometric constraints of the linkage allow calculation of all of the configuration parameters in terms of a minimum set, which are the input parameters. The nu… Webb24 dec. 2024 · In theory, the side of the chassis to which the Panhard bar is attached can affect the way the car handles in left or right turns.

"WebbA four-bar linkage, also called a four-bar, is the simplest movable closed chain linkage. It consists of four bodies, called bars or links, connected in a loop by four joints. Generally, the joints are configured so the links move in parallel planes, and the assembly is called a planar four-bar linkage. " - Theory 4 bar linkage
