Scientific Reports, Published online: 22 August 2026; doi:10.1038/s41598-026-66044-9 Adaptive fast terminal sliding mode control and bionic intelligent optimization for hydraulic cylinder trajectory tracking and error warning

IntroductionCurrent studies mostly realize local single-condition optimization without full-process bidirectional coordinated control, failing to balance smoothness, durability and response speed simultaneously.MethodsComplete bidirectional switching workflows for single-motor independent drive, torque coupling and speed coupling modes are designed with calibrated torque, speed and pressure thres…

Underwater vehicles fill a crucial place in maritime operations, providing support across multiple industries, reaching remote locations despite extreme conditions and reducing risk to workers. They function as surrogate eyes and ears where we cannot be…

I am looking at a simple cantilever beam deflection: I understand the general expression for deflection/force would be: $y_s = \frac{Fx_s^3}{3EI}$ $F_p = \frac{3y_sEI}{x_s^3}$ If you were going to add viscous damping to the bending of the beam, would it be as simple as: $F = \frac{3y_sEI}{x_s^3} - cEIθ_t$ Where the equation for the angle of deflection is $θ = \frac{FL^2}{2EI}$ ? I have seen some …

If I understand how to do the following problem, it will help with the real complicated problem I am actually doing. The problem I wish to understand is how to derive the equations of motion for a magnetic moment $\vec{m}$ that is in a changing magnetic field $\vec{B}$. I know I can use the Lagrangian to quite easily obtain the equations of motion i.e. the motion of $\ddot{\theta}$ and $\ddot{\…

In the fast-paced world of product development, engineers constantly strive for innovation, efficiency, and accuracy. Yet one persistent bottleneck continues to slow the journey from design (CAD) to high-fidelity simulation (CAE): geometry preparation.

Body engineering is no longer just about designing the vehicle structure. It has become a structural intelligence layer that connects safety, NVH, weight, manufacturability and sustainability decisions from the earliest concept stages.

Anyone who has struggled with an arcade claw machine knows that controlling a mechanical arm is not as easy as it looks. Excavator operators face a much harder version of the same problem. They must coordinate several joystick movements to control the machine’s boom, arm, bucket and cab at the same time. Learning those controls […] The post MIT’s New Excavator Controller Could Help Beginners Dig …

Tiny fans worn around the face or neck could help office workers stay comfortable while reducing the amount of energy buildings use for air conditioning, according to new research from Concordia University. The study found that lightweight wearable fans can provide almost as much comfort as conventional desk fans. Because they cool the individual rather […] The post Wearable Neck Fans Could Keep …

Comparing CFD consulting against in-house simulation? The cost per project is the easy part. Here's the capacity question engineering leaders should ask first. The post CFD consulting vs. in-house simulation: what the cost comparison misses appeared first on SimScale .

I am French and I am a student studying mathematics and physics. I would like to get some information about how to model a bridge. My idea is the following: I would like to model a bridge using a mass-spring-damper system. Then, I would apply a mechanical vibration to make the bridge vibrate sinusoidally, and I would recover an electrical voltage using Faraday’s law by setting up a magnet and a c…

UP Diliman (UPD) earned a 100% passing rate as all 11 of the University’s examinees succeeded at the August 2026 Mechanical Engineers Licensure Examination. According to the Professional Regulation Commission, 1,362 of 3,686 passed the examination given in the National Capital Region, Baguio, Butuan, Cagayan de Oro, Cebu, Davao, Iloilo, Legazpi, Lucena, Pagadian, Pampanga, Rosales, […] The post U…

There is a certain contradiction between the formability and strength of auto parts. In this work, the whole-process processing technology of hot stamping soft steel was designed, and 500 MPa grade mild steel (500HS) with uniform microstructure was prepared. To take into account the strength and formability of hot stamping soft steel, here, based on laser welding technology, 500 MPa grade soft st…

This is a simulation involving the assembly of four parts. The assembly process involves fixing the bottom-most part in place and moving the top-most part by -2.6 mm in the y-direction. The goal is to determine the stress and strain for each part. However, the calculation is not progressing at all. Please advise on how to resolve this issue. https://www.simscale.com/workbench/?pid=522354998091871…

Dramatic improvements in computing, sensors and submersible engineering are making it possible for researchers to ramp up data collection from the oceans while also keeping people out of harm’s way.
