step 1, according to test requirements, various different vibration frequencies required to be output by a vibration exciter are drawn up;
step 2, starting a vibration exciter, driving a driven plate to vibrate by a vibrated driving plate, enabling a driven side magnet on the driven plate to generate like-pole repulsion fit with a first driving side magnet and a second driving side magnet on the driving plate, and enabling the driven plate to slide on the driving plate in a reciprocating manner;
step 3, selecting one of the vibration frequency adjusting vibration exciters according to the vibration frequency sequence set in the step 1, and enabling the driven plate to slide on the driving plate in a reciprocating mode according to the set vibration frequency;
step 4, after the reciprocating sliding of the driven plate on the driving plate in the step 3 tends to be stable, voltage wave data of the piezoelectric energy loop and the friction electric energy loop are collected and stored by the processor;
step 5, repeating the step 3 and the step 4 until the vibration frequency test planned in the step 1 is finished;
and 6, analyzing piezoelectric energy data and friction electric energy data corresponding to different vibration frequency states.
