In the working process of the traditional hydraulic excavator, the potential energy could not be properly applied in the course of boom-down, whereas the boom requires additional kinetic energy to rise, resulting in a waste of energy, heating up the system, reducing the service life of the machine. As a solution to this problem, the paper proposes the balance hydraulic excavator, adhering to the energy-saving principle of mechanical design, on the basis of which, turning the traditional hydraulic excavator’s fixed weight into a sliding weight and fuel tank, meanwhile, connecting the sliding weight fuel tank with the boom fuel tank, which constitutes the machinery - hydraulic hybrid balance system to the effect of saving the system energy, improving the overall stability and reliability.

Background: In the whole design process of modular fuel tank, there are some unreasonable phenomena. As a result, there are some defects in the design of modular fuel tank, and the function does not meet the requirements in advance. This paper studies this problem. Objective: Through on-the-spot investigation of the factory, a mechanical design process model is designed. The model can provide reference for product design participants on product design time and design quality, and can effectively solve the problem of low product design quality caused by unreasonable product design time arrangement. Methods: After sorting out the data from the factory investigation, computer software is used to program, simulate the information input of mechanical design process, and the final reference value is got. Results: This mechanical design process model is used to guide the design and production of a new project, nearly 3 months ahead of the original project completion time. Conclusion: This mechanical design process model can effectively guide the product design process, which is of great significance to the whole mechanical design field.

The basic ways of energy-saving methods of the basic soil cultivation in Central Chernozem Region are suggested. Reducing the depth of primary tillage, replacement of moldboard plowing for subsurface soil loosening, combination of several operations and methods in one working process by the use of combined units and wide-coverage units and module-block complexes, the use of "gentle" tillage technologies: lane, zero and others.

As port cranes becoming larger, the electricity and other energy they consumed increase significantly. The research on energy saving of port cranes is increasingly hot nowadays. This paper first discusses the latest research activities on the energy saving measures of cranes. Then, taking the quayside container crane as an example, the measuring method for its energy consumption is presented and analyzed. Finally, an energy saving device for port cranes is designed to convert the motor’s no useful working energy into electricity for lighting. The design, structures and working process of this device are described in detail.

A new structure of hydraulic hybrid vehicle (HHV) with hydraulic transformer (HT) was built and the working principle of the new hydraulic hybrid vehicle was described. According to the operating characteristics of HT and energy-saving optimization conditions of accumulator used the HHV; Energy-saving optimization control algorithm with various operation conditions in different working conditions of vehicle was established. Then, simulation analysis to control performance of energy-saving algorithm was carried out using PID, Fuzzy Logic Controller (FLC) and Fuzzy-PID control strategy. Results show that Fuzzy-PID controller has a small influence on the parameters of energy-saving optimization algorithm of the hydraulic hybrid vehicle and maximizing energy recovery can be achieved in different energy states by Fuzzy-PID controller.

In this work, we consider a method for determining the rational values of the structural and operational parameters of the lever - hydraulic mechanisms of hydraulic excavators based on an analysis of the results of a computational experiment obtained at the output of a mathematical model of a workflow. It is shown that the presence of kinematic connections between the engine (hydraulic cylinder) and the links of the lever-hydraulic mechanism causes a change in the relationship between the operating parameters of the engine and the power parameters implemented on the driven members (bucket, handle and arrow), depending on the geometric parameters (lengths) of links and coordinates of points (axes) connections links. A simulation model of the working process is developed, which allows to determine the operational parameters of the lever - hydraulic mechanisms.
