Head Expander
Head Expander is useful in cases that shaker armature square is not enough to mount large dimension specimen, or more specimens need to be tested at once to save test time.
Head expanders made by lightweight magnesium alloy with higher strength-to-weight ratio and by aluminum alloy with higher cost efficiency. These head expanders have excellent dynamic performances after test of FEA (Finite Element Analysis) and EMA (Experimental Modal Analysis).
