“…The HPA manufacturing process is particularly important to ensure the stability of the HTS under high pressure. In [101], a technology for the hot spinning process of the HPA shell was proposed. A Johnson-Cook constitutive model of the HPA shell material made of 34CrMo4 alloy steel was developed, the parameters of which were obtained experimentally.…”

This review article deals with hydro-pneumatic accumulators (HPAs) charged with nitrogen. The focus is on HPA models used in the study of the energy efficiency of hydraulic systems. Hydraulic circuits with HPA are presented along with their various applications for delivering the required volume of fluid, maintaining the required pressure, ensuring safe operation, safety stop, leak compensation, fluid volume change compensation, pulsation damping, and pressure shock absorption. A general regenerative hydraulic system and a general hybrid hydraulic system are also presented. The review focuses primarily on HPA computational, dynamic, and simulation models. Basic HPA calculation parameters and computational models of energy storage and thermodynamic cycle are presented. Various computational and dynamic models of HPA have been defined, such as the thermodynamic model, simulation model, dynamic model, pulsation damper model, and shock pulse damper model. Research projects that have used HPA in industrial hydraulic systems are reviewed, such as those maintaining operating pressure in an industrial 80 MN open-die hydraulic forging press and acting as a shock pulse absorber in the lifting and levelling module of a tracked mobile robotic bricklaying system. The development of energy storage technology in HPA from various sources is now a global challenge.

Small module tooth-shaped parts (SMTSPs) with characteristics of hollow, thin wall-thickness made of difficult-to-deformed metals, are one of the most precision transmission components, which are traditionally manufactured by tooth hobbing or tooth shaping. Current-assisted splitting spinning (CASS) has been introduced as a method to achieve integrated manufacturing of SMTSPs. A coupled electrical-thermal-mechanical finite element analysis (FEA) model was established based on the ABAQUS software, the deformation characteristics of the small module tooth and the mechanism of tooth filling under current-assisted splitting spinning were investigated. A BP neural network (BPNN) was used to establish the mapping relationship between process parameters of CASS and forming quality evaluation metrics, and the Non-dominated Sorting Genetic Algorithm (NSGA-II) multi-objective genetic optimization algorithm was employed to optimize the forming process parameters. The results show that the material at the tooth tip along the radial direction is in the state of tensile stress along radial and compressive stresses along tangential and axial directions, which promotes the radial flowing of the material and is beneficial the tooth filling of SMTSPs; the tooth saturation increases obviously under pulse current comparing without pulse current; the BPNN combined with the NSGA-II algorithm can reliably optimize the process parameters of the CASS, improving the forming quality of SMTSPs; experiments verified the feasibility of the process and the accuracy of the predictive model based on the optimization results.
