Head Expander

Many types of standardized head expanders can be supplied and special customization is allowed, to meet the expansion needs of the vibration shaker. In actual vibration test, specimen or fixture is often larger than the electro-dynamic shaker armature table, so the original table shall be extended, with a common method to install an auxiliary table. The more stringent requirement is needed for extending table on the working frequency, table weight, table acceleration, amplitude uniformity and lateral movement. HE series head expander has passed the finite element modal analysis, to ensue the product quality from the structure, materials and manufacturing process etc. aspects.
