Modeling and Simulation of Power Hacksaw Machine Using Bond Graph
Authors: Anand Vaz, Aman Maini
Abstract
The mechanism of a machine involves a number of interconnected rigid bodies which interact with each other dynamically. Formulations of dynamics for such mechanisms available in literature, usually either do not reveal the physical aspects involved, or tend to be too mathematically inclined. Aspects of cause and effect are also obscured. In this paper, the multibond graph approach is used as an alternative but powerful method, for modeling the dynamics of mechanisms taking the specific example of a power hacksaw machine, which is quite common in industry. The mechanism is modeled as a combination of rigid links suitably constrained at joints. Bond graph offers the capability for pictorial representation of the dynamics of mechanisms, based on interaction of power between elements, and also depicts the cause and effect relationships. Coding for simulation can be done directly from the multibond graph without deriving system equations. In this work, the program coding is implemented in MATLAB. The simulation results are analyzed, plotted and discussed.
