The Principle of Hamilton for Mechanical Systems with Impacts and Unilateral Constraints

چکیده

An action integral is presented for Hamiltonian mechanics in canonical form with unilateral constraints and/or impacts. The transition conditions on generalized impulses and the energy are presented as variational inequalities, which are obtained by the application of discontinuous transversality conditions. The energetical behavior for elastic, plastic and blocking type impacts are analyzed. A general impact equation is obtained by the stationarity conditions, which is compatible with the most general impact laws and is applicable to various impactive processes straightforwardly. The crux in achieving energetical behaviour which conforms with the physics of the impactive process, is shown to be the consistency conditions on the impact time variations.

Hamilton's Principle as Variational Inequality for Mechanical Systems with Impact

The classical form of Hamilton’s principle holds for conservative systems with perfect bilateral constraints. Several attempts have been made in literature to generalise Hamilton’s principle for mechanical systems with perfect unilateral constraints involving impulsive motion. This has led to a number of different variants of Hamilton’s principle, some expressed as variational inequalities. Up ...

Stability and Attractivity of Mechanical Systems with Unilateral Constraints

In this paper we will give conditions under which the equilibrium set of multi-degreeof-freedom nonlinear mechanical systems with an arbitrary number of frictional unilateral constraints is attractive. The theorems for attractivity are proved by using the framework of measure differential inclusions together with a Lyapunov-type stability analysis and a generalisation of LaSalle’s invariance pr...

Technical Report DC 2012.039 Tracking control of mechanical systems with a unilateral position constraint inducing dissipative impacts

In this paper, the tracking control problem is considered for mechanical systems with unilateral constraints and dissipative impacts. In these systems, impacts are triggered at the exact moment when the constraint is closed. Hence, when a reference trajectory experiences an impact, the constraint of a nearby plant trajectory is expected to close just before or after the impact of the reference,...

Dynamic Load Carrying Capacity of Flexible Manipulators Using Finite Element Method and Pontryagin’s Minimum Principle

In this paper, finding Dynamic Load Carrying Capacity (DLCC) of flexible link manipulators in point to-point motion was formulated as an optimal control problem. The finite element method was employed for modelling and deriving the dynamic equations of the system. The study employed indirect solution of optimal control for system motion planning. Due to offline nature of the method, many diffic...

Constraints to Applying Systems Thinking Concepts in Health Systems: A Regional Perspective from Surveying Stakeholders in Eastern Mediterranean Countries

Background Systems Thinking (ST) has recently been promoted as an important approach to health systems strengthening. However, ST is not common practice, particularly in Low- and Middle-Income Countries (LMICs). This paper seeks to explore the barriers that may hinder its application in the Eastern Mediterranean Region (EMR) and possible strategies to mitigate them.   Methods A survey consistin...
