In the choice of materials, the mechanical performance of 45# steel is good and it has widely usefulness, it is suitable for rack, therefore we choose 45# steel as the materials of rack. 3.2 Check the homemade chassis of Airport special vehicle training simulator Under the effect of the both sides rails force , vertical deformation of rack is: (3-1) Here: F——concentrate force on rail，unit: N； b——rib length at vertical direction of force； I——rib length at force direction； E——Modulus of elasticity In mobile cabin door simulator, b1 and b2 of both sides retractable mechanism are 3.64m and 3.04m, F1 and F2 are both 7500N, E of the 45# steel is 206GPa, I is always 7m.

Introduction Pneumatic conveying is one of the transporting methods that using compressed air (or gas) as the driving force, and the pipeline as a conveying path, depending on the pressure difference of the two ends of the pipeline to conveying materials.
And the recovery coefficient about particles is related to the particle's material properties.
As for carbon black materials being transported, assuming the specular reflection coefficient is 0.005, the recovery coefficient about the solid particle and the pipe inner wall is 0.9, the recovery coefficient about the solid particles is 0.95.

Demagnetizing Experiment of Magnetism-Concealed Tank based on Smart Materials Ying Huang Department of Basic Sciences, Academy of Armored Force Engineering , Beijing 100072, China huangying@guigu.org Keywords: Magnetism-Concealed, Tank, Demagnetizing Effects, Experiment Design Abstract.
Demagnetizing principles about the Magnetism-Concealed Tank Main Demagnetizing Principles Since tanks or armored vehicles are made mainly by steel which belongs to intensive magnetism material, they are magnetized in the earth magnetic field to form specific magnetic field whether they are put into fight or waited for orders in modern electromagnetism battlefield.
It is shown in fig. 1.3 for iron material, setting the magnetic induction intensity on a certain gauging point to be some value marked as point A at the initial state, it decreases gradually along the curve AC, really not declines sharply along the curve AO to 0 when the reverse magnetic field intensityproduced by the degaussing electric current acts on the outer space around the tank for a little while.
