The compliance coefficient of a non-standard part represents the displacement of the top of the bar under the action of the unit force, and the value and stiffness coefficient of the multi-free system in which the single degree of freedom system or the vibration equation are not coupled to each other is reciprocal. . The non-standard parts are mainly the other parts that are not controlled by the company but have no strict standard specifications and no related parameters. The methods for determining the compliance coefficient of non-standard parts are usually based on experiments, and the manpower and material resources are expensive. It is hoped that the flexibility coefficient of fasteners will be studied through theoretical methods, and a new method for calculating the compliance coefficient of non-standard parts will be obtained to achieve the purpose of saving material and time.
Non-standard parts
Using knowledge of material mechanics and elasticity theory, a formula for calculating the compliance coefficient of non-standard parts was deduced. There are many varieties of non-standard parts, there is no very standardized classification, are generally based on market needs and their own brand development, and extend the vitality of the product and independent research and development. In the engineering structure, non-standard parts are commonly used for structural connection. When the fatigue strength of the non-standard parts is analyzed, the flexibility coefficient of the non-standard parts is the necessary parameter for calculating the load transmitted by the fasteners.
