Decoupling method for conceptual design of textile machinery

Textile machinery has many features such as sophisticated process,complex structure and large parts number and so on.For solving coupling design problems encountered in the process of textile machinery designing,the transforming bridge in extension theory was introduced to clear up the coupling problem.Decoupling method of extension theory was proposed after analyzing the relationship between coupling problem of axiomatic design and opposite problem of extension theory.The formal description was made on coupled nuclear issue which was confirmed by the fault tree analysis.Hereby decoupling model and decoupling process of axiomatic design based on the conversion bridge were constructed.An example of vibration and wearing of the twisting winding system verifies the validity and feasibility of the method.
