koneliikettä

Koneliikettä is a Finnish term used in mechanical engineering to denote the movement produced within a machine or a mechanism. It refers to the relative motion of its constituent parts—such as links, pins, gears, and sliders—generated by a driving pair and constrained by the mechanism's joints. In practice, koneliikettä is studied as the kinematics of machinery: how position, velocity, and acceleration propagate through a system with fixed joints and prescribed geometry. The topic encompasses translational motion, rotational motion, and combinations thereof, and is commonly analyzed in terms of a kinematic chain, degrees of freedom, and the constraint equations that relate one part to another.

Common examples include the crank-slider mechanism, four-bar linkages, gear trains, and cam-follower arrangements. Understanding koneliikettä allows engineers to predict output motion from a given input, design for desired trajectories, and ensure smooth and accurate operation. Modeling methods range from descriptive graphical techniques to analytic approaches using loop-closure equations, vector methods, and instantaneous-center analyses; modern practice often employs computer-aided design and multibody dynamics simulations.

In broader context, koneliikettä is a fundamental concept in konetekniikka (mechanical engineering) and robotics, with applications across automation, vehicle engineering, machinery design, and manufacturing. The term emphasizes the motion characteristics of machines rather than their forces, which are addressed separately in dynamics.
