Abstract
This paper analysis the relevant materials of the overhead working truck, the system
design for the special chassis of overhead working truck, including selection of chassis parts,
chassis steering system calculation, and the relevant selection of electric control system, and
analyzed the difficulties by using simulation software. In this paper, the main content is as
follows:
1: On the basis of data collection and sort, understand the all parts of mobile aerial
working platform of straight arm, according to the present data,finish the design of the overall
scheme of the mobile aerial working platform of straight arm2: I design the hydraulic system of vehicle chassis, including of the kinematics,
dynamics analysis of walking steering system, the selection of ponents and
checking3: I made a summary of the related signals, then selected the suitable hardware to
monitor effective signals, such as operation panel, sensors, display module, etc
4: Analysis for synchronous problem: using the Matlab/Simulink simulation for the
diverter valve. For synchronization issues, add shunt device in the system, and us
