Patent number: 11965861Abstract: Disclosed is an equivalent acceleration method of creep loads based on a consistent failure mode. The equivalent acceleration method includes obtaining corresponding tensile strengths; obtaining corresponding creep rupture time; establishing rupture time law, minimum creep rate law and rupture strain law; calculating the value of parameter p in creep damage accumulation model; and dividing the failure mode consistency interval of creep load under variable temperature and variable load. The damage caused by the creep load in the failure mode consistency interval is calculated by using the multi-grade variable temperature and variable load creep nonlinear damage accumulation model, the damage is accelerated to the maximum creep load state in the failure mode consistency interval according to the principle of damage equivalence, and finally the equivalent acceleration of creep load is realized.Type: GrantFiled: May 12, 2022Date of Patent: April 23, 2024Assignee: NANJING UNIVERSITY OF AERONAUTICS AND ASTRONAUTICSInventors: Zhigang Sun, Xu Zhao, Yingdong Song, Xuming Niu, Yaning Chang, Qiuhong Peng

Publication number: 20240111164Abstract: A display system may include a wearable display for rendering a three-dimensional virtual image content which appears to be located in an environment of a user of the display. The relative positions of the display and one or more eyes of the user may not be in desired positions to receive, or register, image information outputted by the display. For example, the display-to-eye alignment may vary for different users and/or may change over time (e.g., as a user moves or as the display becomes displaced). The wearable device may determine a relative position and/or alignment between the display and the user's eyes by determining whether features of the eye are at certain vertical positions relative to the display. Based on the relative positions, the wearable device may determine if it is properly fitted to the user, and position render camera(s) accordingly to present virtual image content.Type: ApplicationFiled: November 30, 2023Publication date: April 4, 2024Inventors: Yan XU, Jordan Alexander CAZAMIAS, Rose Mei PENG
