Design of a Hydraulic-Cylinder-Pressure-based Anti-overturning Module for Aerial Work Platforms

This paper is devoted to the research and development of an anti-overturning module for the secure operation of the aerial work platforms with composite booms structure, as well as in prevention of accidental overturning. The methodology adopted in this paper is based on the hydraulic cylinder pressure detection, which is used to calculate the force that hydraulic cylinder exerts on booms through pressure sensors, in order to deduce the overturning moment. Compared to the regularly used method such as Gaussian integration, theoretical analysis, cutting method and numerical computation, the method of hydraulic cylinder pressure detection requires less calculation and is much suitable for practical application. This paper is primarily concerned with the design of the framework and overall structure of the hydraulic-cylinder-pressure-based anti-overturning module, as well as the development of embedded control system based on ARM & µC/OS-II.
