Abstract

The project requests are set for demining machine design, operating conditions, mobility, transport, performance, remote control, endurance, soil digging density, protection, reliability, maintainability, documentation requirements, and testing requirements. As a result a design of light, medium and heavy demining machines is offered. Calculation is given for machine working conditions, movement resistance and soil digging resistance, the needed force and power for digging the soil. This includes the diagram of resistance force and hammer impulse force in correlation with flail rpm and tool shear. For specific depths of 10–20 cm respectively, specific power to a meter of rotor length is calculated, as well as total flail strength for processing soil of specified category. On grounds of machine movement resistance values and machine work, required engine power is determined, and finally the components of hydrostatic transmission are suggested. The output is a machine concept with two flails and a combined machine concept with flail and tiller. Its features of soil digging and neutralization of AP and AT mines are determined, as well as mine destruction reliability. Since machines often need to perform in toughest climatic and thick dust conditions, what was considered was a design of engine and transmission oil cooling system, together with air filter. Through machine acceptance assessment in real demining conditions, certain dilemmas over machine shaping, with flail, tiller and rollers, were cleared out. A vision of demining machines was suggested in its developing guideline: tele-demining machines and diesel-electric demining machines in ecological acceptability.
