  • Publication number: 20130061653
    Abstract: A crash sled system for simulating the deceleration and pitching motion associated with vehicle crashes. A main sled is accelerated in accordance with vehicle deceleration that occurred during a crash event. A pitching platform is located above and moves with the main sled. Forward and rear guide assemblies are provided which are located along the sides of the pitching platform when the main sled and pitching platform are in the pre-launch position. When the main sled is launched, the front and rear ends of the pitching platform travel along paths established by the guide assemblies. Prior to launch, the guide assemblies are set to angles of inclination that provide linear approximations to paths for the forward and aft ends of the pitching platform that will result in pitching motion experienced by vehicles during the crash events being simulated. Variously configured guide assemblies are disclosed that provide design trade-off between simulation accuracy and system complexity.

  • Publication number: 20130047700
    Abstract: An impact test fixture includes an arm, a testing actuator connected to the arm, and an impactor supported by the testing actuator. The testing actuator is actuatable to propel the impactor at a predetermined speed with respect to the arm. A mass dampener is associated with the arm for reducing deflection of the arm as a result of actuation of the testing actuator.

  • Patent number: 8333104
    Abstract: A measuring device for detecting and evaluating an impact, jolt or the like is formed with an impact face, against which the impact, jolt or pulse which is to be evaluated strikes. A sensor, for example a force sensor, detects values of the force which act on the impact face as a result. A sensor, for example an acceleration sensor, detects values of the acceleration which act on the impact face as a result. An evaluation unit processes the determined force and acceleration values.

  • Publication number: 20120312071
    Abstract: According to one aspect of the present disclosure, a device and technique for impact detection is disclosed. The impact indicator includes a tube having a first fluid and a second fluid disposed therein, wherein a viscosity of the second fluid is greater than a viscosity of the first fluid, and wherein, responsive to a predetermined level of impact received by the impact indicator, at least a portion of the first fluid mixes into the second fluid to create a change in color of the second fluid to provide a visual indication of the received impact.

  • Publication number: 20120266652
    Abstract: An evaluation method for hit feeling of a sport implement according to the present invention includes an acceleration measurement step for measuring acceleration of a sport hitting tool 4 and a data analysis step for analyzing data obtained in the measurement. In the data analysis step, an amount of change in acceleration in a first cycle of vibration after hitting is calculated. The evaluation method evaluates hit feeling to be felt by a person, using the amount of change in the acceleration. Preferably, in the data analysis step, an amount of change in acceleration in the first cycle of predetermined time is calculated. The predetermined time is within 1.5 msec from the time of hitting. Preferably, the sport hitting tool 4 has the hitting section detachably attached to a shaft section.

  • Publication number: 20120247178
    Abstract: An apparatus is disclosed that includes a frame, an impact delivery unit for delivering an impact force and at least one head form. The head form is adapted to be mounted to the frame such that the impact delivery unit can deliver an impact force to a designated location on the head form. The head form is configured to have a helmet installed thereon. The head form is selectively rotatable about each of a plurality of different axes of rotation, wherein movement of the head form is constrained to be able to move only in rotation and in rotation about only one axis of rotation of the plurality of axes at any time. A measuring system provides an indicator of the rotational acceleration of the head form when rotated about each of the plurality of axes. Also disclosed are methods for comparing the degree of protection afforded by first and second helmets.
