Dynamic Analysis of the Press Automation

Abstract

In this paper, we present a geometric exploitation of the d'Alembert-Lagrange equation (or alternatively, Lagrange form of the d'Alembert's principle) on a Riemannian manifold. We develop the d'Alembert-Lagrange equation in a geometric form, as well as an explicit analytic form with respect to an arbitrary frame in a coordinate neighborhood on the configuration manifold. We provide a procedure to determine the governing dynamic equations of motion. Examples are given to illustrate the new formulation of dynamic equations and their relations to alternative ones. The objective is to provide a generalized perspective of governing equations of motion and its suitability for studying complex dynamic systems subject to nonholonomic constraints.  Index Terms-press automation, d'Alembert-Lagrange equation, computed plot, numerical algorithm Kuralay Tulegenova candidate of physicomathematical sciences, Associated Professor,

Estimation of Aircraft Engine Mount Dynamic Forces based on Least- Squares Scheme

“…With the identified dynamic force, the dynamic behaviour of structures and the structureborne noise caused by engine vibration can be calculated. Accurate identification of dynamic forces can be very important to the design process [2]. The dynamic forces caused by engine operation can be measured when engines are installed on the test bench with special force gauges.…”
