Title:
STRENGTH DETECTION METHOD FOR INNER TUB OF LAUNDRY TREATING DEVICE, AND INNER TUB AND LAUNDRY TREATING DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/187022
Kind Code:
A1
Abstract:
Provided are an inner tub (10), a laundry treating device and a strength detection method for the inner tub (10) of the laundry treating device. The inner tub (10) is provided with a strain sensor (20). The method comprises: acquiring a detection value of the strain sensor (20) and generating an actual stress value; performing, based on the actual stress value, inverse correction on initial finite element analysis pre-processing parameters of the strength of the inner tub (10); executing corrected finite element analysis until the degree of overlap between a stress value of a node corresponding to the strain sensor (20) in a corrected finite element analysis result and the actual stress value is greater than or equal to a set degree of overlap; and generating a strength correction model for the inner tub (10). The influence of the dynamic operating strength of the inner cylinder (10) is fully taken into consideration, and inverse correction is performed on an initial finite element analysis result based on an actual stress value, and therefore, the obtained corrected finite element analysis result is highly consistent with the real situation, and a strength analysis result is more accurate, thereby providing an accurate data basis for subsequent production, maintenance and design; moreover, over the course of the whole test process, the simplification of the structure of the inner tub (10) is not destroyed, and the detection method is more rational and reliable.
