foundation, is strongly recommended, but with caution. KEYWORDS: Machine Foundation, Dynamic Response, Seismic Qualification, Design Aids, Vibration Isolation INTRODUCTION The dynamics of machine-foundation system is an involved task in itself and consideration of earthquake effects further adds to its complexity.

The crusher foundation is limited to a concrete deck supported by spring units and Viscodampers®. The dynamic behaviour of this system can be accurately calculated and predicted. Consequently, the design of the supporting structure, RCC or steel, below the spring system can be based on static analysis only.

The deflection of the spring for the load range is 7.5 mm. Assume spring index of 10. Permissible shear stress for the material of the spring = 480 MPa and its modulus of rigidity = 80 KN/mm2. Design the spring. Take Wahle's factor 4 4 4 1 ., C C C 0 615 = - - + 'C' being the spring index. Answer:

Typical Isolated Foundation Configurations. There are two main types of Vibration Isolation systems, Full Isolation (Base and Walls) and Lateral Isolation (Walls only). Elastomeric Isolation elements, Foundation Isolation material and coil spring isolators are all commonly used as isolation elements under isolated foundations and inertia blocks.
