Correct design steps of tension spring:
The task of tension spring design is to determine the diameter D, the number of working cycles N and other geometric dimensions of the drawing spring, so as to meet the strength constraints, stiffness constraints and stability constraints, and further require the corresponding design indicators (such as volume, weight, vibration stability, etc.) to achieve the best
The correct design steps of the tension spring are as follows: first, according to the working conditions and requirements, try to select the tension spring material and spring index C
Since sb is related to D, the diameter D of the spring wire must be assumed in advance. Then, the values of D, N and other corresponding geometric dimensions are calculated. If the results do not conform to the design conditions, the above process should be repeated. Until a solution satisfying all the constraints is obtained, it is a feasible scheme for this problem
In practical problems, the feasible scheme is not unique, and it is often necessary to obtain the optimal solution from multiple feasible schemes
