Description of the system to be simulated
Drum hosting machine

• Drum hosting machine was developed from simple
  winch
• The basic type is hosting machine with two drums
• Hosting machine is useful for transportation
  miners and spoil from mine
• Double-drummed hosting machine has two hoisting
  drums and two ropes with two cages, which drive
  alternately up and down.
• Parts of hosting machine
• rope drums, ropes, main-line blocks, hoisting
  cages, engine

Objectives of the system simulation

• Our target was to simulate
• Acceleration of the hoisting machine
• Usual run of the machine
• Stopping the machine by primary engine
• All simulation proceed in DYNAST software.

5
Strategy of modeling dynamics of the system

• Our modeling strategy was
• Simulation of a simple winch
• Influence weight of unwoven rope
• Deliberation elasticity of the rope
• Inertia of rotaring drum
• Inertia of rope wound on a drum
• Adition of oxygen resistance
• Construction of dynamic speed regulator

6
Subsystems and validation of their models

• We tested our outcomes, and we found out, that
  they are enough for global perspective
• In reality are many other aspects and influences,
  which could affect behavior of the machine

Reflections on experiences gained during the
project

• We learned how to simulate physical situations in
  the computer
• We obtained experiences with work in teams
• We found out how to work by a plan and with a
  deadline
