应用复合材料进行活塞裙部型面的试验

An Experiment for the Determination of Piston Profile by Using Composite Materials

本文研究了利用复合材料确定活塞型面的方法,经广泛筛选和正交试验,利用国产原材料开发出中温复合材料,进行了涂复工艺与磨合程序的试验研究,最后经实机自动磨合成型,得到了S195型柴油机桶形活塞裙部对应于热态最佳型面的冷态型面(可供精加工用)。证明了环氧树脂—铝粉—二硫化钼复合材料涂层能更快和更精确地确定活塞型面。为按工作状态处于最佳形状设计活塞奠定了基础。

The method introduced for finishing the piston skirt profile by using composite materials is presented is the paper.A medium temperature com- posite material from domestic raw material in developed by the aid of screening and orthogonal tests.Under the experimental investigation of coatig technology and rubbing-out procedure,an optimum barrel piston skirt of S195 eng ine is accomp- lished.The investigation shows that the pistons kirt profile is quickly and accurately derived by using the coating composite material of epoxy resin-aluminium powder- molybdenum disulphide.The new method of piston design according to the opti- mum working condition is provided.
