The invention provides a method for simulating real impact test of vehicle wheels, and the method is implemented using a system as follows: the system includes a vehicle used in wheel simulating real impact test, a road surface, a high-frequency lighting facility, a standard obstacle block, a high-speed camera, and a traction motor and steel cable. The method for simulating real impact test of vehicle wheels of the invention has the advantages that: the need for testing various types of wheels using one set of equipment can be satisfied by using a general type collision trolley, thereby avoiding the use of a corresponding real vehicle for each type of wheels in the test. This greatly reduces the test cost, ensures that the test condition is similar to the real vehicle condition, and can well simulate the performance of a real vehicle when meeting an obstacle.

The present invention relates to a test arrangement for the crash simulation of motor vehicles, said test arrangement having a first carriage, which is movable substantially horizontally along a longitudinal axis, and a second carriage, which is movable along the longitudinal axis together with the first carriage, wherein the second carriage is attached to the first carriage in such an articulated manner that the second carriage is movable with respect to the first carriage. In order to be able to simulate actual accident conditions better, in the test arrangement according to the invention, in addition to at least one first actuating element and at least one second actuating element, there is also provided at least one third actuating element, which is configured to accelerate the second carriage in a horizontal direction substantially perpendicular to the longitudinal axis.

An analyzing method of a spot welded portion, includes: acquiring bar elements as the spot welded portion; extracting other bar elements existing at a periphery of a target bar element which is targeted among the acquired bar elements; determining whether or not there is a bar element which shares the same end point with the target bar element among the extracted bar elements; determining that the target bar element and the bar element which shares the same end point with the target bar element are a three-layer spot welded portion when it is determined that there is the bar element which shares the same end point with the target bar element; and determining whether or not there is a bar element whose distance between elements with the target bar element is within a predetermined distance among the extracted bar elements when it is determined that there is not the bar element which shares the same end point with the target bar element, and determining that the target bar element and the extracted bar element are not the three-layer spot welded portion when it is determined that there is not the bar element within the predetermined distance.

A testing fixture for a vehicle includes a tube and a piston slideably disposed in the tube. A seat belt D-ring is mounted t the piston. An actuator is supported on the tube in communication with the piston through the tube for moving the piston relative to the tube to an extended position in a designated time interval during a simulated vehicle rollover. The piston defines teeth, and a ratchet is supported on the tube and engages the teeth of the piston for preventing movement of the piston relative to the tube toward the retracted position during or after the simulated vehicle rollover.

An anthropomorphic test device includes a spine assembly defining a spinal axis; a neck assembly coupled to a head assembly; and a neck bracket assembly coupling the neck assembly to the spine assembly. The neck bracket assembly has a base secured to the spine assembly with a base plane transverse to the spinal axis and a mount secured to the neck assembly and coupled to the base with the spinal axis passing through said mount. A pivot mechanism is secured to the base and mount with the neck and head assemblies pivoting relative to the base and spine assembly in a plurality of head positions. The mount has upper and lower surfaces angled to each other with one of the upper and lower surfaces being positioned at an angle relative to the base plane in all of the plurality of head positions.

A collision simulation test apparatus including a table to which a test piece is to be attached, the table being movable in a predetermined direction, a toothed belt for transmitting power to drive the table, a drive module capable of driving the toothed belt, and a control part capable of controlling the drive module. The control part is capable of controlling the drive module to generate an impact to be applied to the test piece, and the impact generated by the drive module is transmitted to the table by the toothed belt.

An example of a method for time-resolved calculation of a deformation of a body comprises calculating (110) a model of the body during the deformation. The method further comprises calculating (120) a predicted X-ray image for the body for a plurality of time points during the deformation based on the model. The method further comprises obtaining (130) one measured X-ray image of the body each for the time points during the deformation. The method further comprises modifying (140) the model based on the predicted X-ray images and the measured X-ray images.

An optical fiber system for a body part of an anthropomorphic test device is disclosed that includes at least one body part and at least one optical fiber that has a plurality of cores in a spaced and parallel relationship with one another that extend between ends of the optical fiber for sensing positions of the at least one body part. Each of the cores have a plurality of grating sensors disposed along a length thereof capable of determining a position and orientation of the body part.
