| 摘 要： | IntroductionMetallic card clothing is ani mportant part of the cardmachine . According to the textile industry criterion (FZ/T93038 95) ,the micro-hardness of four testing points onthe garnett wire teeth should be tested in order to decidewhether it is up to standard or not . Fig .1showsschematically these four testing points on a garnett wiretooth of metallic card clothing . The first testing point ofmicro-hardness is at0.05 0.1mm from the tip of thetooth and its value of micro-hardness req…

| Abstract: | The quenching process of garnett wire teeth of metallic card clothing heated by flame was researched by use of 3-D finite element method and the equation of boundary condition was established by making use of a model of artificial neural network. The transient temperature field, phase transformation in the heating process, the quenching microstructures and the hardness distribution on quenched garnett wire teeth of metallic card clothing were simulated. The result shows that the maximum error of the hardness between the simulative value and the actual measuring value is 8.0% on only one testing point and errors are all less than 3.0% on other testing points. |
