Abstract
A flexible impact device based on dynamic forces which are applied to the ground in order to activate pressure mines was developed. The chain impact on the ground surface causes considerable force with a relatively low-weight device. This is a relatively simple machine, consisting of chains connected to a rotating drum. The basic model of the drum and a single chain was developed using the DADS (Dynamic Analysis and Design System) program. In the model, the soil is described as a linear elastic material. The calculation of the impact forces or impulses caused by the chain-soil impact is based on Hertz contact theory. The current model was developed for estimation of the ground-surface-level impact forces. A parametric study can be used to optimize the device design.
