Razvoj udarne zaščite za komoro na pnevmatskem topu

Frelih, Tom (author), Klemenc, Jernej (mentor)

Zaključna naloga obravnava razvoj udarne zaščite za varnostno komoro pnevmatskega topa. Udarna zaščita mora brez preboja zdržati izstrelek, ki je trda, jeklena krogla iz krogličnega ležaja. Hitrost krogle je do 300 m/s. To delo predstavlja smiselno pot razvoja rešitve od začetnega raziskovanja, izbora cenovno in tehnično primerne rešitve, numeričnih simulacij v programu LS-DYNA in konstruiranja zaščitnih plošč ter izdelave tehnične dokumentacije. Ugotovljeno je bilo, da je najbolj primerna rešitev izdelava zaščitnih plošč z lepljenjem več tanjših plošč pločevine iz konstrukcijskega jekla.

• Title: Development of an impact protection for a chamber mounted on pneumatic gun

Abstract

The thesis deals with the development of impact protection for the safety chamber of a pneumatic cannon. The impact protection must withstand the impact of projectile, which is a hard, steel ball from a ball bearing, without penetration. The speed of the bullet is up to 300 m/s. In this thesis a development of the solution is presented from the initial research, the selection of a cost-effective and technically suitable solution, numerical simulations in the LS-DYNA software, construction of protective plates and the preparation of technical documentation. The conclusion is that the most suitable solution is to make protective plates by method of gluing several thinner sheets of structural steel.
