In this paper, based on Miner rule, fuzzy analysis was carried out on predicting the fatigue damage, and mathematical model was established by considering loading sequence and interaction between loads and introducing the membership function. The analysis results show that the predicting fatigue life via the "Blurredregion" extension methods is closer to the test results.
Automation of the domestic existing amorphous silicon solar cell production lines has been already realized but packing is still achieved by artificial. So labor intensity is serious and the cost is high. In order to overcome these problems, through the analysis of the packing process, a kind of automatic packing machine is designed. As the most important part of automatic packing machine, automatic packing manipulator, driven by servo motor and cylinder and controlled by PLC, uses electromechanical integration technology to complete cell steering and into the box so as to save manpower and reduce the production cost.
Shortages of skilled labor,extensive dangerous work,and technological advances are forcing rapid change in the construction industry, thus motivating construction automation,research and development of unmanned execution technologies for use to enhance safety has been undertaken.This paper presents an outline of research and development concerning automation of hydraulic excavator performed by applying a 3D vision system,3D information control system, a safety system, a 3D measurement system,and an operator interface communication system.As a result of the verification of the excavation motion suggest the technical possibility of achieving autonomous robotic excavation in moving toward construction automation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
