Bistable Mechanisms 3D Printing for Mechanically Programmable Vibration Control
This work introduces a 3D‐printed bistable mechanism integrated into tuned mass dampers (TMDs) for mechanically adaptive passive vibration suppression. Through optimized geometry, the bistable design provides adaptable vibration reduction across a broad range of scenarios, achieving effective vibration mitigation without complex controls or external ...

Single-cylinder 125 CC stepped piston engine for mobility and portable power generation applications [PDF]
Two-stroke engines is far simpler than four-stroke version from its physical perspective. For a given brake output, two-stroke is lighter, easier to work on, and provide higher power-to-weight ratio than the four-stroke, making it suitable for small ...

Development of a 2-Stroke GDI Engine
Abstract Nowadays, high-pressure gasoline direct injection (GDI) can be considered a standard technology, due to the wide application on 4-stroke turbocharged engines. This technology – in combination with other specific solutions - has been successfully applied to a 500 cc, 30 kW 2-stroke engine, initially developed as a range extender.

Mathematically analysis on two stroke uniflow scavenging system [PDF]
Conventional 2-stroke engines are commonly used for two-wheeled and marine vehicles that have small engine displacement. However problems such as unstable combustion, high fuel consumption rate, high hydrocarbon (HC) emission need to be resolved.

The dielectric elastomer‐based electropneumatic device (DE‐EPD) is a vacuum‐assisted ventricular assist device (VAD) that delivers high performance (85 mmHg, 6.8 L min−1) with low power consumption. Unlike traditional motor‐driven VADs, it is lightweight, quiet, energy‐efficient, and provides pulsatile flow. Validated in a simulated circulation system,
