Apart from the strength requirements, modern lighting pole designs have to meet a number of safety requirements in the event of collisions. The paper compares the experimental tests performed at the collision test track according to EN 12767 with the results of the numerical analysis carried out in Ansys LS-DYNA. The objective of the work is to prepare a new structure of a thin-walled lighting pole of steel which minimizes absorption of the kinetic energy of the vehicle and, simultaneously, its production costs are comparable to those of a standard pole. The tests were carried out at an impact speed of 100 km/h.
The breakthrough in static structural, buckling and modal computer-simulated results can be used for new military purpose applications. The development of hardware resources leads to better simulation in mechanical analysis. Based on the Ansys software, the values presented for the pylon result from a complex analysis. The present paper aims at defining the working parameters for a specific load of 100 tf, as well as presenting the actual software capabilities for military applications. The information provided is valuable for the emerging technologies and the military techniques, being based on the ANSYS simulation.
An ANSYS simulation of the multiphase complex fluid flow motion in a centrifugal device (tricanter) is presented in the paper. This centrifugal device is designed for one step efficient solution for contaminated river water processing with oil and oil products. The proposed tricanter is one of the main objectives of the project named “Common strategy to prevent the Danube’s pollution technological risks with oil and oil products CLEANDANUBE” financed by European Commission within the frame of Romania-Bulgaria Trans-Border Cooperation Program 2007 - 2013 (grant MIS-ETC code 653). Results for liquid phases (water and oil products) and for solid particles motion are presented graphically and are commented.
