Head expander is rather 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. 

ECON is supplying customer series of 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).

Meanwhile, we also supply more complicated head expanders combined with load support guidance for the vibration cases where specimen dimension is large and test needs high over-turning moment to protect shaker suspension system. 

Moreover, customized design and manufacture is available from us for different shapes of fixtures or jigs, as per requirement of customers.
 

Features

  • Assured dynamic performances by FEA and EMA test
  • Optional Magnesium or Aluminum alloy
  • Optional shape of round, square or others
  • Customized pattern holes available
  • Completed design with load support guidance
