In the light of the actual situation of a certain trade center large parking lot, optimized parking design model of the parking lot is built with such data as length, width and minimum turning radius of large buses and cars, the optimized results of the optimum parking composition and arranging angles of vehicles in the parking lot are obtained based on genetic algorithm.

First,minimum turning radius of hypersonic vehicle was calculated.

bending operation of the foundation was introduces,the plane bending belt conveyor to change the natural mechanics and reasonable method of determining the turning radiuswere described,and explore the impact of the belt conveyor plane bending operation of the relevant factors and the introduction of measures to plane bending belt conveyor design were eplored,the installation and use of provid.

Saturation time headways with different lane widths and turning radiuses were measured on the spot and abnormal data were identified and eliminated.

This article analyses the differences between articulated bus and non-articulated bus when they make turn,and derives the calculation methods of the turning radius and passageway width of articulated bus and the angle between the main bus and the sub-bus.

Experimental study on role of mandrel in thin-walled tube NC bending process with small bending radius;

Experimental study on thinning of thin-walled tube NC bending process with small bending radius;

Aluminum alloy thin-walled tubes with small bending radius are one of key components widely used in aviation, aerospace high-technology industries.
