Numeric Simulation of Material Transfer
Technology
MDE offers to contributors, clients and partners high-end technology in high level engineering services. The investment in technological evolution is continuous and there is a constant effort to qualify professionals to adopt such technologies. The company works with conceited partnerships and suppliers of the technology field. MDE continuously invests in network infra-structure and information security in order to ensure a high performance of its applications. It counts on servers and work stations to meet the demands of its users, using engineering softwares that help on the users’ productivity and ensure quality of the projects delivered to the client.
ENGINEERING CAPACITY
One of the major different features of the equipments produced by MDE is pre-production. Modern project tools are used, with details, calculation and numeric simulation of the equipments functioning before they get into production, and thus we avoid re-work and eventual troubles during operation. By the software used by MDE, we can simulate the operation of equipments, optimizing as most as possible for the conveyor’s profile, getting the minimum curve radius to avoid material falling or possible damages in the structure or in the components of the equipment, and also to foresee and to analyze deep rises or drops on the belt tension causing damages at the structural or mechanical part of the equipment, or even in the belt itself. The simulated analysis of start and braking of conveyor can also point out the best curve to activate the conveyor (percentage of torque versus percentage of time), softening the start and increasing the life of equipment’s components, and mainly avoiding over or under dimensioning of structural and mechanical components of conveyors, besides avoiding unnecessary energy expenses. One of the softwares used by MDE also help us to define which is the best inclination of the plates, where it is necessary to have wearing plates, flaps or if it is necessary to increase the chute. By specific softwares we can design equipments with efficiency and quality, reducing costs and manufacturing terms, besides meeting the specific needs for each client.
This state-of-the-art software performs conveyors calculation in the paused and dynamic status, providing data of equipment and components, for the following operational conditions of the conveyor:
a. Operating completely loaded up
b. Operating completely empty
c. Only upward parts of loaded conveyor
d. Only downwards parts of loaded conveyor
e. Start with conveyor completely loaded up
f. Start with conveyor completely empty
g. Braking with conveyor completely loaded up
h. Braking with conveyor completely empty
i. Natural stop with conveyor completely loaded up
j. Natural stop with conveyor completely empty.
It also provides:
a. Minimum radius for convex and concave curves
b. Minimum radius for horizontal curves
c. Analysis of resonance in the belt
d. Movement of belt’s stretching system.
