Mathematical Model of the Lifting Working Mode of a a Mobile Platform with Hydraulic Drive

The paper presents the mathematical model of the hydraulic drive of a mobile platform. The mobile platform hydraulic drive is designed to work with saving and reuse of energy by introducing in the hydraulic system of a hydraulic bladder accumulator and a hydraulic pressure amplifier. The mathematical model refers only to the lifting operating phase of the mobile platform where the accumulator is no active in the driven system. The aim of the paper is to find analytical solutions in the design of the lifting platform hydraulic system. The experimental measurements made it in the lifting phase are used to identify the parameters used in the model.
