        摘要：Impact factors of different speed, operation environment to high-speed train device ventilation were studied and analyzed. The result shows that speed and environment temperature have few effects to device ventilation. Operation in tunnel causes device ventilation rate slight decreasing, and humidity influences pressure head and power of ventilation.

        摘要：With the secondary development to SolidWorks by VisualBasic, parametric design method for driving gear of EMUs motor bogie was researched, and plug-in unit system of SolidWorks was compiled, which realized automated design, parameterized modeling, and automated 2D engineering drawings renewal. Design and analysis speed was enhanced, and product-developing cycle was shortened. This method makes remarkable senses on parametric design of other typical parts which have the same structures and different size.
