In order to simply the design process and reduce the cost, a virtual prototype of spreader was built in this paper, which was used to simulate the operating condition of spreader in the open coal mine. Then the method of test and verification in engineering application is put forward. Finally, it obtains the parameters of system model of spreaders that satisfy the requirements in actual operating condition by analyzing the test results. The results indicate that the virtual prototype could simulate the real condition and provide exact data for the stable operation and maintenance of spreaders.
The vibration mode of main steel structure of bucket wheel stacker reclaimer is complex and changeable, so its modal analysis is necessary. In this paper, the main steel structure of bucket wheel stacker reclaimer was integrally designed and its main parameters were determined. then the finite element model of the main steel structure of the bucket wheel stacker reclaimer was established and the modal analysis was simulated, finally the results of its inherent frequency were calculated by FEA method.
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.
