#Article 📜 Design of Soft Pneumatic Actuator with Two Oblique Chambers for Coupled Bending and Twisting Movements by Ebrahim Shahabi, Behnam Kamare, Francesco Visentin, Alessio Mondini and Barbara Mazzolai 🔗 https://lnkd.in/g7GhP6Wg MDPI; Istituto Italiano di Tecnologia; Scuola Superiore Sant'Anna; Università degli Studi di Verona #actuator #finiteelementanalysis #softactuator #Abstract Soft pneumatic network (Pneu-net) actuators are frequently used to achieve sophisticated movements, but they face challenges in producing both bending and twisting motions concurrently. In this paper, we present a new Pneu-net twisting and bending actuator (PTBA) design that enables them to perform complex motions. We achieved this by adjusting the chamber angle, ranging from 15 to 75 degrees, to optimize the bending and twisting movements through finite element analysis and experimental verification. We also investigated the variation trends in bending and twisting motions and determined the actuator’s workspace and maximum grasping force for a variety of objects with different shapes, materials, and sizes. Our findings suggest that PTBA is a promising candidate for advanced applications requiring intricate and bioinspired movements. This new design method offers a path toward achieving these goals.

Breakout session Filtration I: Generation of cylindrical pleated structures for the digital optimization of filter flow performance In recent years, there's been a growing emphasis on leveraging digital tools for designing filter elements, using Computer-Aided-Design (CAD) for both micro and large-scale simulations. However, the systematic simulation of diverse geometrical setups involves the time-consuming process of individually generating and importing CAD structures. To overcome this challenge, we've developed an eco-efficient digital framework for designing cylindrical pleat structures with variations in pleat count, thickness, and porous layers. Here's what we'll discuss in our Breakout Session: 💡 We show you how to simulate various filter structures to identify the most efficient configuration, minimizing pressure drop while striking an ideal balance between filter area and pleat count. 💰 This digital testing approach reduces the need for costly physical testing, ensuring only the most promising prototypes undergo further evaluation. 📊 To enhance efficiency, these systematic simulations can be conducted on cloud platforms, enabling simultaneous runs of various geometries or flow rates.

My passion for best SAW wide band filter design which I continuously strived for as a design engineer (between August 1999 till March 2001) at RF Monolithics Inc. (Now part of Murata company) located in Dallas, Texas, USA, is still strong and I always stress on high linearity wide band low insertion loss SAW filter. Here is a link of a paper that every persuasive SAW filter design engineer should find of immense interest and even design their CAD software taking assistance from this article. Side lobes are not much attenuated in this filter design but that is expected for 5G and 6G cellular applications where reject band spectrum are very close to each other.

This paper presents the design of fully metallic 3D #Vivaldi #antenna that can be used for wireless power transmission applications. The 3D antenna consists of 1) a tapered profile, 2) a rectangular cavity, and 3) a horizontal slot cut that is used as a transition between the cavity and the tapered profile. The proposed antenna design is fabricated using two distinct approaches, the first of which is a 3D metal #additive #manufacturing (#AM #scheme) with a sequential material layer addition technique. The second version is based on the #CNC #milling (#CNCM) technique implemented by selectively removing material in a controlled way. ---- Sunanda Roy, Karthik Kakaraparty, Ifana Mahbub More details can be found at this link: https://lnkd.in/efMUakG2

⚪️ How does precise geometric optimization of SLM-printed AlSi10Mg radial heat sinks—by adjusting fin outer and inner heights, fin length, fin thickness, and number of fins across heat fluxes from 300 to 1800 W/m²—significantly enhance thermal performance for LED cooling under natural convection conditions, as demonstrated through comprehensive simulations and experiments? ●●●●●●●●●●●●●●●●●●●●●●●●●●●● Geometric Optimization of SLM-Printed AlSi10Mg Radial Heat Sinks for Enhanced LED Cooling Syed Waqar Ahmed, Khurram Altaf, Adeel Tariq, Mohammed Alkahtani, Johannes Buhl & Ghulam Hussain 🔬 Impact of Fin Geometry on Thermal Performance The study investigates how varying fin dimensions—outer and inner heights, length, thickness, and quantity—affect the thermal performance of radial heat sinks made via selective laser melting (SLM) of AlSi10Mg for LED cooling. 🌡️ Key Findings  -Fin Thickness Influence: Notably affects base temperature, especially at higher heat flux levels.  -Heat Flux Interaction: Fin length and heat flux interplay is crucial for temperature control.  -Optimal Configuration: Higher fin outer heights with lower fin inner heights lead to superior performance, keeping base temperatures below 70 °C. “The results underscore the significance of fin thickness, which notably influences the base temperature of the heat sink, particularly at higher heat flux levels,” state the authors. 🔗 Read the full study to understand how geometric adjustments enhance thermal management in LEDs: [https://lnkd.in/dyEnjSHe] #HeatSinkOptimization #SLMPrinting #AlSi10Mg #LEDCooling #ThermalPerformance #EngineeringResearch ⚡️ Ultimate Takeaway Optimizing fin geometry in SLM-printed AlSi10Mg radial heat sinks significantly improves thermal performance under natural convection, providing effective cooling solutions for LED applications.

In this picture, taken from Nissan #electricmotor manufacturing process of an 8-pole Permanent Magnet Synchronous Machine, you can notice 2 grooves per pole on the rotor surface. 🧐 Adding grooves (also called notches) on the rotor surface modulates the reluctance path of the PM flux around the circumference, affecting rotor field space harmonics. 💡This notching technique is common to reduce cogging torque, but it may be also used to reduce noise and vibrations due to magnetic forces. In general, there is no correlation between peak to peak cogging torque, coming from the interaction of several force harmonics in circumferential direction, and acoustic noise, which may related to a single force harmonic in radial direction. 🤩 Notching technique can easily be applied in #Manateesoftware on both rotor & stator bore radius, with several parametric shapes or user-defined shape. Do you use notching on your #electricmotor design? What pattern do you use and for which purpose?
