Abstract:
In recent decades, agricultural vehicles equipped with a power transmission unit consisting of a hydraulic drive have become widely used. Thus, in agricultural tractors, the hydraulic drive implements one of the energy flows in the hydraulic-mechanical transmission. Axial-piston hydraulic machines, which can be controlled or uncontrolled, are introduced in such means. During the operation of agricultural tractors with hydraulic-mechanical transmissions, a wide range of dynamic loads is applied to the hydraulic transmission, which causes the appearance of jump-like values of torque and angular

Problem. The creation of transport vehicles for operation in difficult road conditions requires solving a complex of problems related to the fulfilment of the necessary requirements for speed and traction characteristics, in particular, shifting modes, overcoming climbs, manoeuvrability and increased speed with its stepless change, anti-skid properties. Such requirements are achieved thanks to constructive solutions in transmissions of various types. Goal.

Abstract:
Design method of hydraulic system of full hybrid transmission was analyzed. At first, oil volume flow and pressure requirement was confirmed according to the vehicle control strategy. Mechanical gear pump and electric pump were used to supply oil flow for all driving modes. Self-adapted pressure regulation circuit was designed to supply high pressure oil for brake engagement. Structure dimension of valves and cooling orifices was designed by theoretical calculation. Cooling flow can be distributed proportionally among electric motors and planetary gears.

Abstract:
Unlike hydraulic systems of conventional automotive transmissions, the hydraulic system of a hybrid vehicle must cope with large variations of pressure as well as flow. If supplied by traditional pump configurations, either fixed or variable displacement, the system will incur substantial efficiency losses. This paper presents a feasibility study of a dual-pump hydraulic supply system which consists of a low-volume fixed-displacement pump and a high-volume variable-displacement pump. The analysis addresses the dynamic characteristics of this system along with its sensitive design areas.

The success of theoretical engine noise prediction, using such techniques as finite element modelling, is highly dependent upon the understanding of the various mechanisms of noise generation in the running engine.

A number of test methods have been developed to simulate individually each one of these loading mechanisms on non-running engines. These test methods are reviewed in this thesis with an objective

Abstract:
The solutions to today’s energy challenges need to be explored through alternative, renewable and clean energy sources to enable a diverse national energy resource plan. An extremely abundant and promising source of energy exists in the world’s oceans in the forms of wave, tidal, marine current, thermal (temperature gradient) and salinity. Among these forms, significant opportunities and benefits have been identified in the area of wave energy extraction. Waves have several advantages over other forms of renewable energy such as wind and solar, in that the waves are more available (seasonal, b
