Abstract
A structure to provide increased surface area on the head of a shaker used for vibrational testing. The structure includes a base plate for attachment to the head of the shaker and a larger expanded head connected thereto by a frustoconical structure surrounding a cylindrical structure surrounding a spoke structure, all designed to increase the vibrational frequency at which undesired vibratory modes appear in the surface of the expanded head which otherwise can provide nonuniform vibration loading to the items attached thereto during testing. The structure also includes improved means for attachment to the shaker.
