“…The primary methods for gas compression encompass mechanical techniques (like piston and diaphragm compressors), and centrifugal compression [146,147]. Other advanced methods include ionic liquid piston compression [148], and electrochemical compression (based on PEM electrolysis principles) [149]. In recent times, there has been a growing adoption of metal hydride hydrogen compressors owing to their notable benefits such as: enhanced safety, environmental compatibility, minimal vibration and noise, effective sealing, absence of friction, efficient hydrogen purification, and reduced maintenance expenses [150][151][152].…”

This article aims to optimise the structure of a press machine to enhance its stability and accuracy, as well as reduce the frame deformation during processing. The outer supporting frame of the JH31-250 press machine (Zhejiang Weili Forging Machinery Co., Ltd, Shaoxing, China) is used as a typical sample for exploring optimisation. Commercial software is utilised to conduct a finite element analysis on the three-dimensional model of the press machine frame. A topological optimisation algorithm using the solid isotropic microstructures with penalisation (SIMP) method is then applied to improve the structure of the press frame. The size of the topological structure is further refined with the response surface method and particle swarm optimisation method to ensure it is more relevant to engineering application. The analysis results indicate that the initial frame’s deformation under the static conditions is 0.4229 mm, and after optimisation, the deformed structural displacement is 0.2548 mm, a decrease of 39.75%. Additionally, a simplified experimental method is designed to effectively validate the simulation and the proposed design.

Summary The ionic liquid compressor is regarded as the most promising compression technology for the hydrogen refuelling station due to the combined application of ionic liquid and the hydraulic driving system. However, the design, mathematical and experimental investigations of the ionic compressor are still absent from the open literature. This paper proposed a new structure design and the design methodology of the ionic liquid compressor. The mathematical modelling considering the valve dynamics was provided for simulating the thermodynamic process, which was verified by the experimental data. The results showed that the delayed closing of the discharge valve would take place due to a high or low stiffness of the valve. The increase in the stiffness alleviated the rebound issue of the suction valve. An increase in the stroke to diameter ratio could solve the rebound issue of the discharge valve. A low or high trajectory coefficient would cause an intense rebound during the closing procedure of the discharge valve. The designed results of the main parameters of the compressor based on the simulation were the suction valve stiffness of 100 N/m, the discharge valve stiffness of 500 N/m, the stroke to diameter ratio of 1.0, and the trajectory coefficient of 0.125 under the given design condition.
