Abstract:

In this paper the author present a new physico-mathematic model which describe the movement of the frontal changer. The technological equipment is considered as a dynamic system with two masses (the base machine and the equipment loaded with change in the bucket) and five degrees of freedom. The motion of the machine is described by the set of differential equations, based on the second order Lagrange Principle, with proposed hypothesis of energy dissipative systems. To computing the solution for these equations, it was used the classical numerical methods, implemented on the MATLAB™ software numerical application. The model and the method presented in this work constitute a starting original approach for analysis both of a motions of each constitutive elements of the machine, and of a dynamic stresses and strains of the changer equipment metallic structure. The main purpose in this study consist by underlie a complex and complete numerical model, which leads the simulations and the analysis of the effects of the vibrations, produced in the metallic structure of the technological equipment, for the different phases of the working cycle.
