Vibrating screen is an equipment used to seperate material according to its particle size. It is usually operated in combination with a crusher. A vibrating screen prototype has been developed. This prototype, called as "Pengayak Getar Semen Padang Prototipe"”0l" (PGSP PRO-01), employs an eccentric shafi

This paper discusses numerical solution of natural convection in concentric annulus. Artificial Compressibility Method has been used to solve two dimensional Navier Stokes equations. And to strengthen the relationship between pressure and velocities, pressure was placed on the cell center, whereas the velocities and temperature were placed on cell vertex. Navier Stokes Equations were divided into discrete forms by finite volume method, so that flow conservation could be kept balance. The computation results show no significant difference with the other results solved using other…

This work is based on method developed by Storer, Lee and Tomlinson [1,2,3]. Storer [1] determined parameter of nonlinear system by curve fitting of higher order FRF that was obtained by measuring stimulus and response of nonlinear system in the frequency domain. While Lee [2] determined spatial model parameter i.e. mass, stiffness and damping constant based on higher order FRF that was obtained from measurement of excitation force amplitude in time domain and complex response in frequency domain. In this paper the two methods will be compared by conducting experiment on the ball bearing…

The objective of the present research is to develop an application software called MSC (Manufacturing System Core) which is used as a core in the development of a manufacturing system software. The development of MSC is based on ADiMS (A utonomous Distributed Manufizcturing System). An object-oriented modeling method is adopted to represent the autonomous component of the manufacturing systems. The example of minimum application of MSC and the method of extent are discussed to understand the modularity of MSC. Software development technology applied at MSC are discussed to see the ability of…
