Voltage dependence on the geometric parameters of coils screw mechanism
The paper used the theoretical and experimental approaches to solid mechanics. Processing of the results of research carried out using the methods of mathematical statistics and the theory of experimental, mathematical modeling methods. The calculations were determined by the relative values of equivalent stresses. These numerical experiments were processed to obtain the regression model, reflecting the dependence of the equivalent stress: the geometric parameters of the coil – the angle of the profile and the pitch of the thread, the height of the coil, the displacement of the contact point on the loop height, strength (ratio) of friction. Take into account the displacement of the contact point with the average diameter of only towards the top of the coil. The adequacy of the resulting mathematical model is confirmed by the experimental investigation of the stress state of the coil segment polarization-optical method.
