By using basic formula method for common spring and trial calculation method for general fuze spring

there are unbridled calculation

repeated trial calculation and large calculation amount at designing cylinder helix compression spring of fuze with few known parameter.Reverse calculation method was proposed with parameters of spacial dimension

total compressed height

average resistance and corresponding test height based on trial calculation method for general fuze spring.According to known conditions and value constraint conditions

the structure parameters of spring were calculated reversely by using corresponding formula.Correctness of spring parameters value is verified by basic formula method for common spring and trial calculation method for general fuze spring.Repeated trial calculation for uncertain parameter is avoided by reverse calculation method

and the method is not only applied to constraint conditions with plenum chamber and core rod

but also applied to constraint conditions with plenum chamber or core rod individually.
