4) The entire class of seat belt-related flexion-distraction injuries to the spine are commonly referred to as ‘Chance-type’ fractures. These fractures are caused by hyperflexion around a lap belt, with the belt acting as a fulcrum. This mechanism of hyperflexion and distraction would also explain the frequent association of intraabdominal injuries as viscera are crushed between the lap belt an...
Rear seat adult occupant protection is receiving increased attention from the automotive safety community. Recent anthropomorphic test device (ATD) studies have suggested that it may be possible to improve kinematics and reduce injuries to rear seat occupants in frontal collisions by incorporating shoulder-belt force-limiting and pretensioning (FL+PT) technologies into rear seat 3-point belt re...
OBJECTIVES The objective was to determine the association between the abdominal seat belt sign and intra-abdominal injuries (IAIs) in children presenting to emergency departments with blunt torso trauma after motor vehicle collisions (MVCs). METHODS This was a planned subgroup analysis of prospective data from a multicenter cohort study of children with blunt torso trauma after MVCs. Patient ...
In this research, we studied the fault recognition algorithm of steel cord conveyor belt, and obtained the wire ropes image by adopting the detection system of steel cord conveyor belt, so that the fault recognition algorithm of steel cord conveyor belt was proposed based on Fruit fly optimization algorithm. As we know that the fruit fly optimization algorithm is used for fault detection of the...
According to the actual working conditions of the Vribbed belt, automobile V-ribbed belt fatigue tester machine is designed to test for the automobile engine Vribbed belt fatigue wear. Finite-element analysis software ANSYS is employed to perform finite-element analysis on fatigue testing machine load shaft, bearing, universal joint key parts of the finite-element analysis, and to analyze the m...
At present, the environmental problem is increasingly serious, how to achieve sustainable development has become very important recently. This paper used data of 106 prefecture-level cities Yangtze River Economic Belt study effect regulation on green total factor productivity. The results show that can significantly improve GTFP. There significant heterogeneity. Also found level economic a thre...
