Design of Body And Frame System of Heavy-duty Electric Automatic Guided Containers Transporting Vehicle
Abstract
In order to improve transportation efficiency, reduce costs, streamline management, and improve port transportation environment, etc., one of the development trends of container terminals is to promote the development of container terminals in the direction of automation and intelligence. The heavy-load unmanned electric container transport vehicles (AGV) is a key link in the automation and intelligentization of container terminals. The design of frame and body of the heavy-load unmanned electric container transport vehicles is the key. Strength and stiffness are the crucial factors on designing its frame. The crucial factors on designing its body are providing installation position of some assembles like the battery system and fixing containers when carrying. Due to the heavy load of this AGV and its own large mass, and its function of bearing its own mass and various of load as well as providing position for installing other assembles, the design of frame will be mainly illustrated， including the design procedures of the main frame and the auxiliary frame. After obtaining the parameters of frame by numerical calculation, the three-dimensional model of frames are built with UG 10.0 and the finite element analysis is conducted on them, which will provide more direct and detailed judgement for the frame.
The research result indicate that: the design frame can meet the requirement of strength and stiffness, and providing installation position for other assembles. Besides, the vehicle body realize its function.
The feature of this paper: the AGV involved in this article is a super-heavy unmanned electric vehicle. The frame is said to bear heavy loads. In order to ensure that the frame meets the requirements, both numerical calculations and finite element analysis will be applied.
Key Words：AGV; main frame; auxiliary frame; vehicle body; stiffness; strength; finite element analysis
