Title:
RIDING VIBRATION PREDICTION SYSTEM AND METHOD OF ROAD SURFACE BICYCLE
Document Type and Number:
WIPO Patent Application WO/2020/103305
Kind Code:
A1
Abstract:
A riding vibration prediction system and method of a road surface bicycle (2). The method comprises: first, obtaining a contact interface between a road surface and a bicycle tire by using a pressure film (9); then calculating a unit bearing area (B u) and an average stress peak spacing (Sp a) by using the contact interface as a foundation; then by using the unit bearing area (B u) and the average stress peak spacing (Sp a) as variables, calculating a predicted riding vibration value (P v) by means of a calculation formula; and finally comparing the predicted riding vibration value (P v) with the vibration sensing threshold of the rider of the bicycle (2). The present invention can perform rapid and effective grading and prediction on the riding comfort of a section of asphalt road surface.
