The paper studies, from the electromechanical point of view, a medical apparatus designed for spine treatment by vibrations. The differential equations of motion of the system have been obtained by using Lagrange equations ...

This paper presents a product time and cost estimation method taking into account the market dynamics and manufacturing system competitiveness. The method is based on the behavioral modeling using on-line unsupervised ...

The vibrations of many mechanical systems can be described by differential equations that have coefficients that depend on time. It is difficult to determine the approximate or exact analitical solutions of these equations. In ...

In practice, decisions on order acceptance and on production planning are often made separately. Sales department is responsible for accepting orders, while production department is in charge of production planning for ...

During the operation of mechanisms operated by hydraulic cylinders significant energy losses occur. They is due to the loss of flow, pressure and friction losses that occur in the system. This paper highlights the connection ...

In this paper the numerical simulation of the concrete mixer was developed in SimMechanics, a toolbox for Matlab environment. The virtual model for mixing equipment simulation has been computed to estimate the increase ...

This paper aims to show the 3D modeling of a bucket crusher equipment attachable to the excavator arm. The static analysis of this type of crusher jaws allowed a correct designing for a better reliability. This analysis ...

In this paper the parameters of the acoustic field were studied experimentally,along with the frequency produced by the generator and the circular diagram of the generator’s acoustic emission, the influence of the nozzle’s ...

The models of demolishing jaws and pulverizers that are already on the market give us the necessary information for the development of a research program regarding the optimum choice of the necessary machinery in demolishing ...
