Noise/Vibration Control TRIZ Cases
- Brake Damping Device Segmented Gas Volume for Short Pedal Travel
Segmenting the gas volume with a pressure-activated closure element limits pedal travel length while maintaining reliable damping effectiveness.
- Piston Manufacturing Device for Disc Brake Noise Reduction
A piston manufacturing device forms an annular groove and a thick section to stabilize the contact surface area.
- Electromagnetic Brake Noise Reduction via Damping Rings and Spacers
Elastic spacers and damping rings on the armature disk prevent direct coil core contact, reducing impact noise during braking cycles.
- Disc Brake Pad Preload Spring for Knocking Noise Reduction
Tangential preload spring reduces transverse clearance between brake pad and carrier, eliminating knocking noise from kinetic energy release during gear shifts.
- Railway Brake Disc Groove Design for Noise and Cooling
Segmented fin grooves lower aerodynamic noise while maintaining cooling performance under high-speed thermal expansion.
- Pad Spring Surface Roughening for Coating Adhesion
Basket sanding roughens pad springs to enhance coating adhesion, resolving defects from smooth surface preparation.
