Head Expanders
Unholtz-Dickie Corporation (UD)
By increasing the mounting area of the shaker, multiple items can be tested at the same time, decreasing total test cycle time. In addition, with Guided Head Expanders, payloads with large foot prints can be safely mounted and tested on the shaker, minimizing the risk of damage to the shaker suspension system. Although many head expanders are resonant below 1000 Hz, average or extremal control allows operation to 2000 Hz.
