Research on Mechanical Dynamics with a Use of a Vehicle Wake Generating Device Simulation and Design

There is rich automotive wake and wind resource on the highway. Power can be used for power generation, supply of electrical equipment or the highway into the grid .The paper proposes a new wind vertical axis wind generator. According to the actual conditions ,the important institutions are needed to optimize device emulation. The dynamics of shaft has a major impact on the stability of the power plants work. Use ANSYS to provide a reference for further optimization agency. Radial pendulum balls mounted to the whole device can be stable on the shaft buffer.

New Intelligent and Efficient Pesticide Sprayers in Mechanical Manufacturing Engineering

In view of the traditional low mechanization,degree of automation and lack of humanization etc, a n-ew intelligent and efficient pesticide spraying machine can be created to add pesticide to cotton.Completed parametric design of the devices virtual prototype by SolidWorks,and we apply virtual prototyping technologyto key parts to go on dynamics simulation analysis,to verify the reasonableness of this mechanism design and correctness of the function to achieve.

Deposition of BaTi2O5 Films on Si Substrates by Using MgO Buffers

Using the (100)-Oriented MgO Thin Film as the Buffer Layer, BaTi2O5 Films Were Deposited on Si(100) Substrates by Pulsed Laser Deposition under Various Oxygen Partial Pressures (PO2). the Effects of PO2 on the Crystal Phase, Orientation and Surface Morphology of the as-Deposited Films Were Investigated. Single-Phased Bati2o5 Films Were Obtained at PO2 = 10-15 Pa, and the Preferred Orientation Changed from (710) to (020) with Decreasing PO2. at PO2 = 10 Pa, the BaTi2O5 Films with a Higher Degree of bItalic text-Axis Orientation and a Dense Texture Were Deposited on the Mgo(100)/Si(100) Substrates. The MgO Buffers Played an Important Role as Structural Templates for the Textured Growth of BaTi2O5 Films on Si Substrates.

Laser Energy Dependent Structure of Pulsed Laser Deposited Barium Dititanate Films

Barium dititanate (BaTi2O5) films were prepared on MgO (100) substrate by pulsed laser deposition under various laser energy densities. The effect of laser energy on crystallinity, orientation and surface morphology was investigated. The preferred orientation of the as-deposited films changes from (710) to (020) with decreasing laser energy, and the surface morphology is different depending on laser energy too. The b-axis oriented BaTi2O5 film could be obtained at the laser energy density of 2J/cm2, where the film shows a dense surface with an elongated granular texture.
