ANALYSIS AND DESIGN OF KING POST USING STATISTICAL APPROACH

Abstract

The steerable antennas having paraboloidal reflectors are used for Satellite Communications (SATCOM) purposes. For proper functioning of these antennas which are important part of a SATCOM system, their design need to be carefully considered and these antennas should have very high degree of reliability. King Post is an important component of the antenna system. In the present dissertation, the analysis and design of the King Post of a typically large size antenna, has been presentee_ on the basis of reliability based design. The design variables are considered as random variable and design and analysis is done using statistical design approach. A high amount of reliability or low value of probability of failure is considered for the component. The statistics of King Post diameter and deflection is found and compared with the results of classical design approach.
