Özet:In defense industry, the environmental conditions play very critical and dangerous roles for valuable and sensitive electronic equipments. One of the most dangerous situations is high level shocks caused by explosions. In order to protect the valuable assets from the dangerous effects of shock some special designed shock absorbers are needed. For some shock absorbing cases, standards products manufactured according to the Military Standards are used and their implementation is considerable easy. Helical, wire rope springs and dampers directly attached onto the platforms can be given as an example of that systems. On the other hand, according to the device specifications and its working principle, some special and custom designed shock absorbing systems are required. Shock absorbing platform of naval radars mounted on the ship structure is one example of this custom shock absorbers. At the same approach land and air radars use special absorbing methods. In this thesis, a 3-dof translational shock absorbing parallel manipulator for radar systems is introduced and analyzed in terms of kinematics and dynamics by using rigid body assumption. For that purpose, a parallel manipulator which has only 3 translational degrees of freedom is selected among three candidates and shock absorbing elements (spring, damper) are implemented on it. This special shock absorbing platform is analyzed dynamically according to shock criteria given in MIL-STD 810F
