    Programmable Decelerator for Sled Test
    MESSRING has redesigned its well proven crash pulse simulation system.
    Since 1997 we upgrade car- and sled test facilities with hydrobrake systems.
    Our customers all around the globe are satisfied working with this reliable high performing system.
    Based on the experience of these customers we developed a system which is a cost effective alternative to any acceleration system available.
    With the hydrobrake you get a tool that enables you to simulate crash pulses that can not be realized by conventional systems in a nondestructive way.
  • Crash pulse simulation on car and sled test facilities capable for upgrade of existing facilities
  • Excellent accuracy of pulse reproduction and velocity plot
  • Fast test preparation through automatic adjustment
  • Comfortable user interface and easy programming
  • Fast modification of crash pulse by integrated software tool
  • Capable for duplex operation on car test facilities
  • High testing rate by short converting time
  • Maximum braking force 2 MN or 3.2 MN
  • Space and cost effective system
  • High performance and reliability
  • Bending Bar Brake System
    Bending Bar Brake consisting of sheet metal brake system with roller guides and height adjustable sheet metal rests on both sides, including all fastening elements, max. stopping force app. 1 MN.
    PU-Tube Brake System
    Brake body with 3 x 3 holes, ø 60 mm, to take up to 9 PU tubes with a maximum length of 850 mm. Depending on the diameter of the brake olive, affixed to the mandrel, each tube can generate a braking force of up to 100kN. After braking, the mandrels are hydraulically pressed out of the brake.
    They are divided longitudinally, so they can be easily pulled off the brake mandrels.
    The scope of supply includes 1 set of PU tubes. The braking force can be adjusted by varying the number of tubes and the diameter of the so-called “olives” that are screwed to the front of the brake mandrels.
    Three sets of 9 olives are supplied: undersized, normal and oversized.
