ABSTRACT: To prevent wheeled defence vehicles from flipping over or bursting tyres during mortar firing, spades are used to connect to the ground because it transmit some amount of mortar firing forces to the ground. The addition of spades to the wheeled defence vehicle leads to the heavy increase in consumption of fuel and finally results in considerable time is required to plant into the ground and also retreat after firing. The military (defence) tactical and combat vehicles are being used in more demanding conditions than ever before traditional suspensions to keep up with changing conditions. Thus, design of multiple dampers in structures which may lead to the higher weight, complexity in the design and increase the cost as well. In this work, in order to resolve all above problems, semi-active MRF (magneto-rheological fluid) sandwich beams are proposed to enhance mobility, tire traction and vehicle stability and safety. The sandwich beam considered in this work is modeled as a single degree of freedom system and vibration parameters are determined from the governing equation. The fabricated sandwich beam is tested under four different conditions with and without the magnetic field. 

Keywords : Sandwich beam with controllable core, damping factor, Natural frequency, Loss factor, Logarithmic decrement.
