  • Publication number: 20130160519
    Abstract: An impacting head using in an impact testing device comprises a substrate made of aluminum or aluminum alloy and a rubber head made of polyurethane resin, the substrate and the rubber head are bonded together by adhesive layer mainly containing epoxy resin. The impacting head has low cost and a long service life. Furthermore, the impacting head produces a display of trapezoidal waves following impact tests which meets the requirements of the IEC 60068-2-27 2008 standard.

  • Publication number: 20130014558
    Abstract: A shock and impact testing device includes a shock and impact module and a control module. The shock and impact module includes a base, a platform, an elastic cushion positioned on the base, an elastic impact pad positioned on the platform facing the cushion, and a lifting structure connected to the platform to drive the platform to rise and then release the platform to allow the platform to fall down until the impact pad hits the cushion. The control module includes an interface configured for inputting impact parameters, a converting unit and a control unit. The converting unit calculates corresponding testing parameters according to the impact parameters. The control module controls the lifting structure to drive the platform to rise according to the testing parameters.

  • Publication number: 20130008227
    Abstract: A shock and impact testing device includes a shock and impact module and a control module. The shock and impact module includes a platform, an air cylinder having a rod, an impact head positioned on the platform aligning with the rod, and a lifting structure connected to the platform to drive the platform to rise and then release the platform to allow the platform to fall down freely until the impact head hits the rod. The control module calculates a pressure of the air cylinder and a height difference between the impact head and the rod, and controls the lifting structure to drive the platform to rise to a height difference between the impact head and the rod meets the calculated height difference and adjusting a pressure of the air cylinder to meet the calculated pressure.
