Abstract:The sub-frame of 2500HP fracturing truck is an important component, which connects to chassis with the vehicle equipment. Because the sub-frame bears tension, torsion and bending loads, enough rigidity and intensity are necessary for chassis. Based on the Pro/E software, the 3-D model of frame and sub-frame was constructed. Using topology optimization method, layout of the sub-frame was determined and location of crossbeams was arranged. Meanwhile, number and location of the connectors between main frame and s… Show more
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.
