Recent field data have shown that the occupant protection in vehicle rear seats failed to keep pace with advances in the front seats likely due to the lack of advanced safety technologies. The objective of this study was to optimize advanced restraint systems for protecting rear seat occupants with a range of body sizes under different frontal crash pulses. Three series of sled tests (baseline ...

Abstract A crawler system provides much larger ground contact, leading to excellent terrain adaptability. Due its structural characteristics, high‐frequency vibration proportional the vehicle speed is generated during driving process. This a result of polygon and rolling effects between track wheels. field test tracked performed monitor movement signals chassis rocker arm. Their corresponding p...

Ocean energy is an underutilized renewable source compared with hydropower and wind power. Therefore, the development of economical efficient wave converters (WECs) important crucial for offshore power generation. The mooring tensioner a critical device that can be used in point-absorber-type WECs, semisubmersible floats oil gas drilling, floating turbines. A system to create, reduce, or mainta...
