The paper deals with erosion of bone cement using a pulsating water jet at pressure 15 MPa, comparing the effectiveness standard and extended nozzle length 100 mm diameter d = 0,3 mm. research addresses problem optimizing removal techniques, which is critical for various medical applications, including revision surgeries removal. study employs an design experiments where samples are subjected to system equipped both specially designed nozzles. Key parameters such as maximal depth, groove...
This research article outlines our aim to perform topology optimization (TO) by reducing the mass of connecting rod an internal combustion engine based on static structural and dynamic analyses. The basic components like rods, pistons, crankshaft, cylinder liners were designed using Autodesk Inventor Professional 2025. Using optimization, we aimed achieve lesser maximum von Mises stress during analysis maintain a factor safety (FOS) above 2.5 rigid body dynamics. A force 64,500 N was applied...
Selective laser melting (SLM) can produce complex metal components with high densities, thereby surpassing the limitations of traditional machining methods. However, achieving accurate dimensions, geometries, and acceptable surface states in parts fabricated through SLM remains a concern as they often fall short compared to traditionally machined components. As solution, hybrid additive-subtractive manufacturing (HASM) method was developed effectively utilize advantages both techniques. In...
Erosion of solids by liquid droplets is a phenomenon which compromise between mechanical properties the material and droplet hydrodynamic parameters. While number studies deal with deformation drops, evolution inside has not yet been revealed, mainly from point view time action impinging drops The response AISI 316L was investigated under gradually increasing numbers impingements droplets, volume Vd ≅ 0.9 mm3, generated an ultrasonic pulsating water jet frequency f = 40 kHz 1 to 20 s....
A pulsating waterjet is a technological modification of conventional that utilizes ultrasonic vibrations to generate modulated jet, resulting in repetitive fatigue loading the material. The erosion efficiency majorly determined by hydraulic factors and its interaction with standoff distance. However, dependency wear rates on different formulation an implicit prediction model for determining effective distance still not present date. Therefore, this study, combined supply pressure (20-40...
A pulsating water jet (PWJ) offers advantages over a continuous jet, such as lower liquid volume flows and pressures for deeper cuts. However, traditional PWJ setups are unsuitable minimally invasive surgeries due to their size. This study aimed develop instrument by testing 100 mm long, 10 diameter extension tube. We evaluated (1) the machining capability of with tube on simulated hard tissue (2) impact submerged environment cutting capacity. Using 20 kHz ultrasonic were provided erosion...
Additively manufactured/printed represent a high potential for their use in various branches of technical practice. However, applicability requires knowledge the maximum application limits, or intensity damage due to external factors. This article investigates testing 3D printed materials produced via Selective Laser Melting (SLM) treated by an ultrasound excited pulsating water jet (PWJ). The study focuses on two frequencies, 20 kHz and 40 kHz, applied AISI 316L stainless steel AlSiMg10...
This study presents pioneering experiments utilizing an ultrasonic pulsating water jet (PWJ) for drilling into aluminum alloy 5.5 mm thick following a circular trajectory with diameter of 6 mm. The innovative approach combines the high frequency pulses 20 kHz impinging surface material at Bernoulli impact speed was 254 m/s to enhance efficiency and observe precision. Circular trajectories 10, 15 20x transition provided basic information on characterization erosion process factors entering...
