Rimpact’s Bolt-on Mass Damper Aims to Soften Fatigue on Gravel Rides

Rimpact’s bolt-on Tuned Mass Damper for gravel forks weighs about 400 g and costs £229.99, claiming to reduce rider fatigue by smoothing the headtube energy from bumps. It’s marketed as an energy-delay device rather than a true damper, with no hydraulic damping, and is not meant to replace a suspension fork. Early measurements suggest the total energy reaching the headtube is similar with or without the unit, but the peak impact is lower, implying a smoother ride. Although the concept has seen uptake in downhill racing, the author stresses that clearer communication is needed and calls for blind testing to verify real-world benefits.

Taiwan's Resilience: Surviving and Searching After Earthquake

Taiwan's tallest skyscraper, Taipei 101, withstood a recent 7.4-magnitude earthquake with minimal damage, thanks in part to its innovative design featuring a 660-metric-tonne steel sphere known as a tuned mass damper. This pendulum-like device, nicknamed "Damper Baby," sways to counteract the building's movement, reducing its sway by up to 40%. The damper, suspended over 1,000 feet above the ground, is designed to absorb the force of intense swinging during earthquakes or typhoons, showcasing innovative engineering to safeguard structures in earthquake-prone regions.

Taiwan's Resilience: From Earthquake Preparedness to Global Sympathy

Taiwan's tallest skyscraper, Taipei 101, withstood the recent 7.4 magnitude earthquake using modern engineering techniques. The building's reinforced concrete construction and a tuned mass damper, a large orb-like device suspended within the tower, allowed it to sway and counteract the earthquake's powerful motion. The skyscraper's deep foundations, strict anti-seismic building codes, and extensive testing also contribute to its resilience. The tuned mass damper, which is also used in skyscrapers worldwide, protects against harmonic vibration and reduces the uncomfortable effects of swaying on occupants during high winds.

"Taiwan's Tallest Skyscraper Unscathed in 7.4 Magnitude Earthquake: Resumes Work After Shutdown"

Taiwan's tallest skyscraper, Taipei 101, utilizes a 660-ton tuned mass damper, resembling a massive pendulum, to safeguard itself from earthquakes, such as the recent 7.4-magnitude tremor. The device, located between the 87th and 92nd floors, reduces the tower's movements by up to 40% and is crucial in withstanding seismic activity and typhoon winds. Taiwan's susceptibility to earthquakes is attributed to its location on the Pacific "Ring of Fire," but the nation's strict enforcement of seismic building codes and emergency preparedness have significantly mitigated potential damage.

"Taipei 101's Resilience: Surviving Taiwan's Massive Earthquake"

When a 7.4-magnitude earthquake hit Taiwan, Taipei 101's tuned mass damper, a 730-ton steel sphere, helped absorb the shock and reduce the building's movement by up to 40 percent. The skyscraper, known for its resilience to natural disasters, is equipped with other features such as deep piles and redundant power supply. Taiwan, located in the seismically active Ring of Fire, faces frequent earthquakes, making such engineering innovations crucial for the safety of its skyscrapers.
