AI Technical Summary

Technical Problem

In the prior art, only a single series or parallel model is considered to deduce the equivalent Young's modulus, resulting in inaccurate equivalent of the Young's modulus of the secondary transposition Litz line.

Method used

The parallel flexibility model along the length direction of the secondary transposition Litz line, the series and parallel flexibility model along the width direction, and the series and parallel flexibility model along the thickness direction were constructed. Taking into account the common influence of the transmission of series and parallel force, a more accurate equivalent Young's modulus was calculated by weighted average.

Benefits of technology

The simulation accuracy of the secondary transposition Litz linear mechanical properties is improved, and the equivalent Young's modulus is closer to the actual structure, which is improved.

Abstract

The invention provides a method and a device for determining equivalent Young modulus of a secondary transposition Litz line. The method comprises the following steps: constructing a first parallel flexibility model along the length direction, a second series flexibility model and a second parallel flexibility model along the width direction, and a third series flexibility model and a third parallel flexibility model along the thickness direction of the secondary transposition Litz line; determining a first equivalent Young modulus of the secondary transposition Litz line along the length direction based on a first parallel flexibility model; determining a second equivalent Young modulus of the secondary transposition Litz line along the width direction based on the second series flexibility model and the second parallel flexibility model; and determining a third equivalent Young modulus of the secondary transposition Litz line along the width direction based on the third series flexibility model and the third parallel flexibility model. The common influence of the two conditions of series force transmission and parallel force transmission on the Young modulus is closer to an actual structure, and the accuracy of mechanical simulation of the secondary transposition Litz line is improved.
