“…During the last decades, they have been extensively investigated to substitute the conventional rigid mechanisms since they offer several benefits, including simplicity, fewer parts, precision, weight reduction, improved performance, and versatility [9]. They have been widely used in various applications, such as biomedical engineering [10,11], high-precision flow control valves [12,13], energy harvesting mechanisms [14], feed drive mechanisms [15], and equipment for VAMs. Piezoelectric actuators (PZTs) that could offer extremely precise displacement at tens of microns combined with CMs to transfer and amplify the original motion is a popular way to design non-resonant VAM equipment.…”

Vibration-assisted machining, a hybrid processing method, has been gaining considerable interest recently due to its advantages, such as increasing material removal rate, enhancing surface quality, reducing cutting forces and tool wear, improving tool life, or minimizing burr formation. Special equipment must be designed to integrate the additional vibration energy into the traditional system to exploit those spectacular characteristics. This paper proposes the design of a new 2-DOF high-precision compliant positioning mechanism using an optimization process combining the response surface method, finite element method, and Six Sigma analysis into a multiobjective genetic algorithm. The TOPSIS method is also used to select the best solution from the Pareto solution set. The optimum design was fabricated to assess its performance in a vibration-assisted milling experiment concerning surface roughness criteria. The results demonstrate significant enhancement in both the manufacturing criteria of surface quality and the design approach criteria since it eliminates modelling errors associated with analytical approaches during the synthesis and analysis of compliant mechanisms.

Piezo teknolojisi, elektrik enerjisi ve hareket enerjisi arasında geçiş imkânı sağlaması sayesinde çok sayıda sektörde kullanılmaktadır. Özellikle düşük enerji tüketimi, hassasiyeti, sessiz çalışması, kompakt yapısı, hızlı anahtarlama imkânı, oransal çalışma ve hafiflik gibi özellikleri ile piezo teknoloji pnömatik uygulamalarda önemli bir avantaj sağlamaktadır. Yön denetimi, oransal basınç kontrolü, oransal debi kontrolü, pozisyonlama, soft-stop ve benzeri temel uygulamalar, kontrollü ve dijitalleşen pnömatik sistem uygulamalarına dönüştürülmektedir. Bu çalışmada, piezovalfler ile çalışan bir pnömatik silindir ve konum sensörleri ile deneysel bir test düzeneği kurulmuş ve hareket kontrolü uygulaması gerçekleştirilmiştir. Uygulamanın deney sonuçlarında sistem karakteristikleri grafiksel olarak gözlemlenebilmekte ve sonuçları analiz edilebilmektedir.

“…Previous research on high-flow and fast-response valves has primarily focused on proportional/servo or HSV [15][16][17]. In recent years, there has also been significant progress in the field of pilot valves for HSV [18,19]. However, it is almost inevitable to have spool structures when controlling flow direction in hydraulic systems using proportional/servo valves [20].…”

Solenoid valves in coal mining equipment are driven by intrinsically safe solenoids. The low power consumption of these solenoids limits the response time of the solenoid valves. Additionally, the low viscosity and high susceptibility to dust contamination of the emulsion fluid often leads to leakage and sticking of hydraulic valves. To address these issues, this study proposes a low-power-driven, large-flux, fast-response three-stage valve structure with an internal displacement feedback device. The driving power of this structure is less than 1.2 W. The key parameters of the valve were optimized using a novel multi-objective optimization algorithm. A prototype was manufactured based on the obtained parameters and subjected to simulation and experimental verification. The results demonstrate that the valve has an opening time of 21ms, a closing time of 12ms, and a maximum flow rate of approximately 225L/min. By utilizing this valve for hydraulic cylinder control, a positioning accuracy of ±0.15mm was achieved.
