Slider position control for slider-crank mechanisms with Jacobian compensator

Proceedings of the Institution of Mechanical Engineers, Part I: Journal of Systems and Control Engineering, 2019
In this work, a position control for slider-crank mechanisms without Jacobian and joint measurements is presented. A Jacobian compensator that depends on the sign of the direction of rotation of the input link and the output link is proposed. A linear sensor is mounted at the slider to measure its position.

Adaptive control of slider-crank mechanism motion: simulations and experiments

International Journal of Systems Science, 1997
Abstract The dynamic motion of an adaptive controlled slider-crank mechanism, which is driven by a permanent magnet ( PM) synchronous servo-motor, is studied. First, the mathematical model of the motor-mechanism coupling system is developed, where Hamilton's principle and the Lagrange multiplier method are applied to formulate the equation of motion ...

The dynamics of the harmonic space slider-crank mechanism

Journal of Mechanisms, 1966
Abstract This paper deals with the distribution of mass in the links of the simple harmonic space slider-crank mechanism to achieve the desirable features of inertia balance and constancy of total kinetic energy during the cycle.

Chaotic And Periodic Dynamics Of A Slider-Crank Mechanism With Slider Clearance

Journal of Sound and Vibration, 1994
Abstract The problem of a planar slider-crank mechanism with clearance at the sliding (prismatic) joint is investigated. In this study the influence of the clearance gap size, bearing friction, crank speed and impact parameters on the response of the system are investigated. Three types of responses are observed: chaotic, transient chaos and periodic.

Hypocycloid Gear Mechanism Versus Slider-Crank Mechanism in Engines

Volume 10: 2019 International Power Transmission and Gearing Conference, 2019
Abstract This effort investigates the feasibility of using the Hypocycloid Gear Mechanism (HGM) as an alternative to the conventional slider-crank mechanism for Internal Combustion Engine (ICE) applications. Engines incorporating the conventional slider-crank mechanism are subjected to high frictional power losses mainly due to the ...

Optimum synthesis of a slider‐crank mechanism using geometric programming

International Journal for Numerical Methods in Engineering, 1980
AbstractGeometric programming is a powerful technique and its application to mechanism synthesis has not been fully explored. In this paper, slider‐crank mechanism is chosen since the objective function consists of a large number of terms while there are only two design variables.

Kinematic Analysis of Slider-Cranks Derived from the $$\lambda $$-Mechanism

2013
In this paper a kinematic analysis is presented for slider-cranks derived from the \(\lambda \)-mechanism. In particular, for this linkage the coupler curves traced by a reference point are Berard curves. By properly choosing the design parameters of the mechanism the coupler curves are represented by quartics, which have been identified and classified.

Dynamic modeling of a slider-crank mechanism with coupler and joint flexibility

Mechanism and Machine Theory, 1994
Abstract Modeling and dynamic analysis of a slider-crank mechanism with flexible joint and coupler is presented. The equations of motion of the mechanism are formulated using a newly evolving multibody formalism and cast in terms of a minimum set of generalized coordinates through a Jacobian matrix expansion.

Unbalanced Inertia Forces in Slider-Crank Mechanisms of Large Eccentricity

Journal of Applied Mechanics, 1958
Abstract An analysis of the various harmonic orders of the inertia forces in offset slider-crank mechanisms is presented. The formulas given here are valid for all practical values of eccentricity ratio (ratio of offset to length of connecting rod) and crank to connecting rod ratio.

Synthesis of a slider-crank mechanism with consideration of dynamic effects

Journal of Mechanisms, 1970
Abstract A method of dynamic synthesis of a slider-crank mechanism to meet specified velocity conditions at three design points including the inertia effects of the masses of the main links is presented. Velocity specifications are developed assuming a constant velocity of the input crank.
