Title:
CONTROL METHOD FOR ELECTROMAGNETIC BALLISTIC SHOCK WAVE GENERATOR
Document Type and Number:
WIPO Patent Application WO/2023/029273
Kind Code:
A1
Abstract:
A control method for an electromagnetic ballistic shock wave generator, comprising the following steps: S1, by means of a sensor (62), detecting impact strength or acceleration of a previous collision of a projectile body (3) with a treatment head (2); S2, using a PWM control means to cause a second electromagnetic coil (61) to power on and operate, and adjusting a PWM duty cycle of the second electromagnetic coil (61) between a preset minimum value and maximum value by means of interpolation according to the detected impact strength or acceleration, so as to drive the projectile body (3) to return to and remain at an initial end position; S3, when a preset treatment interval is reached, powering off the second electromagnetic coil (61), and powering on a first electromagnetic coil (6) to operate to drive the projectile body (3) to move to a collision end and impact the treatment head (2); S4, repeating steps S1-S 3 until treatment ends. In a return phase, the PWM control mode is used, which improves energy efficiency and solves the problem of discontinuity in impact; and in a firing phase, a power-on time of the first electromagnetic coil (6) is dynamically adjusted according to strength data obtained by the sensor (62), thereby ensuring consistency of the impact energy.
