Surface Pressure Test Method and Its Application to Cylinder Gasket Development
Surface pressure test method is widely used in the design of cylinder gasket,trial production and mass production stage,through the Surface pressure test can qualitatively and quantitatively analyze the sealing condition of the engine cylinder gasket,for the emergence of problems such as insufficient local face pressure,sealing tendon fracture and so on to be improved,to prolong the life of the engine,and to improve the reliability and stability of the engine.Test surface pressure paper usually has two kinds,one is a quantitative measurement of the film surface pressure paper,a qualitative judgment of the carbonless copy paper made of surface pressure paper.At present,the industry mostly use carbonless paper to do the Surface pressure paper for the test,ac-cording to the color of the intensity of judgment,low cost and easy to operate,but can not extract the value of quantitative analysis,so it is recommended that only in the cylinder cushion batch of post-production sampling:and in the cylinder cushion R&D stage is recommended to use quantitative measurement of the Surface pressure paper,although the cost is high,but it can improve the analysis of the accuracy of the color concentration,can be realized in the computer visualization of pressure and data analysis,can also be compared with the previous da-ta,more precise and multi-faceted data analysis of sample parts.
