Innovative Design of High Speed Balancing Bunkers

摘要

Some industrial facilities, such as those associated with the energy industry, are designed for incidental high speed impact from airborne debris that might accidentally originate within the facility. High-speed rotor balancing bunkers are among those industrial facilities that require design for incidental high speed impact. Under such extreme loading scenarios, the design of reinforced concrete structures becomes a challenging task. When high speed projectiles impact the concrete, the structure might be breached, or a crater might be generated. An acceptable level of damage to the structure can be established with the facility operator. The level of damage can be identified in terms of the size of the crater, the projectile penetration depth and the minimum perforation thickness. This acceptable level of damage serves as the performance criteria to which the structure is designed. This paper will present a suggested analysis and design process of industrial facilities subjected to high speed impact loading. As an example, the paper will focus on a commercial high speed balancing facility. The suggested design procedure is a collaborative team work between the designers and the facility operators, and it requires the identification of the potential impact scenarios, the use of High-Fidelity Physics Based simulations in order to investigate the structure response under high speed impact. Three-dimensional finite elements models were used to simulate the impact of various projectiles with structure walls. The LSDYNA software was used for all simulations.
