This research focuses on the injury potential of children seated in forward-facing child safety seats during side impact crashes in a near-side seated position. Side impact dynamic sled tests were conducted by NHTSA at Transportation Research Center Inc. (TRC) using a Hybrid III 3-year-old child dummy seated in a convertible forward/rearward child safety seat. The seat was equipped with a LATCH...

The Higher-Order-Mode (HOM) power deposition is one of most crucial problems in the KEK B-factory to achieve a total beam current of 2.6A at the Low Energy Ring (LER). The estimate shows that the HOM power of about 20 kW can pass at any point in the arc of the ring. A particular worry is the Interaction Point (IP) where the maximum tolerable heat deposition of the IP chamber is only 200 W. Two ...

Actual applications of the energy absorbers showed that actual loads are not applied in the form of pure axial compression, pure bending or pure torsion. In reality, an energy absorber component may be subjected to combined loading of compression, bending and torsion. A number of previous articles have investigated the behavior of energy absorbers under oblique loading. In such cases, the obliq...

In view of application to debris flow/rockfall barrier system, several types steel wire mesh were selected verify their basic behaviour under impact load free fall weight at the controlled testing environment an in-house facility capable dropping a heavy on approximately 1-meter square panel made such material. Out 3 tested, high-performance chain link endured highest energy, while newly develo...

In this study, different plate fixing designs were tested in order to improve rock bolting performances. Instead of commonly used steel nuts, investigated by both laboratory and site studies. addition, the usability nuts energy absorbers made polyamide type engineering polymer was assess whether they are advantageous for aim supplying high-energy absorbing features. experimental deformation-con...
