AI Technical Summary
Technical Problem
Existing methods for determining the stiffness of silicon-based balance springs in watch movements suffer from dispersion and interference due to neighboring springs, leading to noisy vibrational responses and inaccurate measurements.
Method used
A device is used to isolate silicon-based balance springs by applying vibratory excitation and measuring their response, featuring a mounting with openings to reduce parasitic vibrations and a clamping plate for precise positioning and measurement, allowing cleaner vibrational analysis.
Benefits of technology
The device provides clearer vibrational peaks for accurate stiffness determination, reducing interference and improving measurement reliability by isolating individual springs from neighboring vibrations.
