BRIEF ANALYSIS OF THE MECHANICS PRINCIPLE OF PERFORMANCE OF STABBING THROAT WITH SILVER SPEAR1)

  • According to the force state of the silver spear, the mechanical models of the slender compression rod and the simple-supported beam are established, respectively, the relationship between the force on the throat of the performer and the bending deformation of the spear is obtained, and some performance skills are suggested. The main conclusions include: (1) For stabbing throat with a silver spear as a compression rod, even if the spear has a large deformation, the force on the performer's throat is not very large. Measures for reducing the force on the performer's throat include: increasing the rod length, reducing the rod thickness, using a softer rattan stick and a blunt tip, and bending the spear as quickly as possible. (2) The performance as a simple-supported beam is not a "real stabbing throat act with silver spear". The bending and deformation of the spear depends on the force of the auxiliary performer. The piercing force on the performer's throat is not very large.
