Abstract: A method for testing the lumbar spine performance of a crash test dummy includes the following steps: selecting a lumbar spine performance test item; collecting data of at least one preset physical quantity during the collision process between the pendulum and the energy-absorbing buffer block through sensors on the lumbar spine assembly; determining whether the data of each preset physical quantity is within the corresponding data channel; if the data of each preset physical quantity is within the corresponding data channel, the lumbar spine assembly is deemed qualified for the current lumbar spine performance test item. This disclosure evaluates the quality of the lumbar spine performance of crash test dummies, allowing only those with better lumbar spine performance to participate in crash tests, and therefore improving the consistency and accuracy of different crash test dummies' response in crash tests.

Abstract: A drop test system includes support members offset from each other and having corresponding tracks, a lifting rod bridging the support members and having rod ends adapted to engage with the tracks to move along the tracks, and a pair of spiral cams adapted to rotate in unison and positioned to engage with and reciprocally lift and drop the lifting rod as the spiral cams rotate. The spiral cams each have a perimeter shape that includes an abrupt section and a curved section that connects to opposing ends of the abrupt section with a smooth curvature. The lifting rod is adapted to ride on the perimeter shape of the spiral cams and gradually lift and drop a unit under test (UUT) as the spiral cams rotate.

Abstract: A pallet tester includes a pallet positioning station for positioning a pallet on a conveyor, and a pallet impact station adjacent the conveyor and aligned with the pallet positioning station. The pallet positioning station includes a pallet push arm movable between a retracted position and a pallet positioning position. The pallet impact station includes a carriage assembly to impact the pallet, and a latching mechanism coupled to the carriage assembly. A controller moves the pallet push arm to the retracted position to receive the pallet for positioning, and moves the pallet push arm to the pallet positioning position to move the pallet towards the pallet impact station until an impact side of the pallet is aligned with an impact reference plane. The controller also operates the latching mechanism to raise the carriage assembly, and to release the carriage assembly when a height of the carriage assembly corresponds to a desired release height so that a predetermined impact force strikes the pallet at the impact reference plane.

Abstract: An automated method and system of determining movement and/or deformation of an anthropomorphic test device (ATD). The method and system includes an acoustic transmitter device located on a first region of the ATD and an acoustic receiver device located on a second region of the ATD. An electric field is provided in communication with the acoustic transmitter to activate the acoustic transmitter for generating mechanical waves to be received by the acoustic receiver. Relative locations of the acoustic transmitter device and the acoustic receiver device are determined by the time of flight of the generated mechanical wave traveling from the acoustic transmitter device to the acoustic receiver device while the first region of the ATD and/or the second region of the ATD are subjected to movement and/or deformation; and determining movement and/or deformation data of the second region of the ATD. Information may be transmitted that represents the movement and/or deformation data of the second region, or information may be presented that represent the movement and/or deformation data of the second region on a display.

Abstract: A method of detecting a preload of a linear guide includes: applying an external force to the linear guide with an external force applying device, wherein the external force applying device sends an impact signal while applying the external force; sensing with a sensor a vibration signal sent from the linear guide because of vibration thereof which occurs under the external force; and receiving the impact signal of the external force applying device and the vibration signal of the sensor and calculating the preload of the linear guide according to a received result, with a signal analyzer. Therefore, with the method of the present invention, the preload of the linear guide is precisely tested regardless of environmental factors.

Abstract: Methods and apparatuses are provided for evaluating or testing stiction in Microelectromechanical Systems (MEMS) devices utilizing a mechanized shock pulse generation approach. In one embodiment, the method includes the step or process of loading a MEMS device, such as a multi-axis MEMS accelerometer, into a socket provided on a Device-Under-Test (DUT) board. After loading the MEMS device into the socket, a series of controlled shock pulses is generated and transmitted through the MEMS device utilizing a mechanized test apparatus. The mechanized test apparatus may, for example, repeatedly move the DUT board over a predefined motion path to generate the controlled shock pulses. In certain cases, transverse vibrations may also be directed through the tested MEMS device in conjunction with the shock pulses. An output of the MEMS device is then monitored to determine whether stiction of the MEMS device occurs during each of the series of controlled shock pulses.
