Definitions

  • the invention relates to simulators for boxing and other types of power martial arts, where it is required to evaluate the strength and energy of an athlete’s blow, his physical form and even the level of boxing skill, and can also be used as an entertainment attraction.
  • the most common sensors used to measure impact force are strain gauges, piezoresistive, and piezoelectric force sensors. All of them are calibrated, have high accuracy and are actively used to measure the impact force in technological processes, since they were developed for these purposes. But blows, as a rule, are not applied to sensors, but to parts or elements used in the technological process. Pressure is transmitted to the sensors through materials or media that have completely different properties. Naturally, having after the impact at the output of the sensors only the shape of the shock pulse, we can talk about the strength of the impact only in some relative units. When performing technological operations, the absolute values of the impact force, as a rule, are not important. Nevertheless, the calibration of measurements, even in cases where the properties, sizes and shape of the colliding bodies does not change, is very complicated.
  • blows are also applied not to hard sensors, but to various damping pads and devices that protect the hands of athletes from possible injuries. And when it is necessary to obtain absolute values of the force of impacts, the task becomes complicated and becomes practically unsolvable even in the case of choosing one target target, since the shock limbs are different, and the shock standard does not exist.
  • the impact force by measuring the impact force using these sensors, they ultimately measure the force arising from the impact and try to interpret it as the desired impact force, and it is determined by the laws of physics by the elastic properties of the target and impact limb, as well as their size, shape and relative speed of movement.
  • SUBSTITUTE SHEET (RULE 26) the collision of two bodies (shock limb and target) with certain properties, shape and mass, it is not possible to carry out an unambiguous calibration.
  • the blow is much more complex and long-lasting than a simple collision. Therefore, having only the shape of the shock pulse and not having a full calibration, it is impossible to obtain correct results when measuring the force and energy of the impact using strain gauges, piezoresistive and piezoelectric force and pressure sensors.
  • the simulator contains a suspended impact projectile, inside of which there is an elastic capsule connected to the display unit by means of a pressure sensor installed inside the capsule, and one or more functional transducers of the pressure sensor signal.
  • the elastic capsule is made of a viscoelastic incompressible material, and a membrane type piezoelectric transducer equipped with a sub-membrane chamber is installed as a pressure sensor, while the inputs of the functional transducers are connected directly to the piezoelectric transducer of the piezoelectric transducer directly or through a matching element.
  • Functional converters and display unit are made on the basis of a computer, while the sound card of the computer is used as an input of functional converters.
  • the disadvantage is the inaccuracy of the measurement results for the reasons described above.
  • the basis of the present invention is the task of creating a simple and at the same time high-tech and reliable device that allows you to measure the strength and energy of an athlete’s impact in numerical equivalent, as well as evaluate the athlete’s physical form and level of boxing skill.
  • the technical result consists in increasing the accuracy of measuring the impact strength of athletes using standard boxing bags, eliminating the need for calibration.

  • a single sensor can be used in the simulator, while it is located in the geometric center of the impact zone, which is also the center of gravity of the bag, while the ratio of the length of the bag to its diameter does not exceed 1.7.
  • the number of sensors can be three or more, while they are vertically along the central axis of the bag at the same distance equal to or less than the diameter of the bag, and the ratio of the length of the bag to its diameter is more than 1.7.
  • the simulator may have a second mode of operation, in which the sum of the energies or impact forces (tonnage) for a certain period of time is displayed, which allows us to evaluate not only the physical form of athletes, but also the level of boxing skill.
  • the simulator may further comprise a coin acceptor; connected to the display unit and configured to return coins, provided that the numerical expression of the result of the blow on the indicator will contain two or three identical digits.
  • the simulator may further comprise one or two sensors of angular accelerations located on the housing at the maximum distance from the vertical and horizontal axis of the bag.
  • the invention is illustrated by drawings, where fig.l trainer presented with a single sensor disposed at the center of gravity coinciding with the geometric center of the deposition zone ud 'moat; figure 2 is one of the possible forms of the bag; in Fig.Z - version of the simulator with three sensors located vertically along the central axis of the bag, where 1. a boxing bag (target);
  • the simulator contains a boxing bag 1. All standard boxing bags for our task can be divided into two groups: short if L / D ⁇ 1.7 and long if L / D> 1.7. Short bags can also include all pear-shaped bags, as well as bags having the shape shown in figure 2. In the latter case, only the dimensions of the massive part of the bag are taken into account.
  • the size of the striking zone F is approximately equal to the diameter of the bag D, therefore, placing the sensor in the geometric center of the striking zone coinciding with the center of gravity of the bag, all strokes delivered with the same force in the direction of the sensor at any point in the zone will have the same * value.
  • the acceleration sensor 2 and the signal processing unit 3 are fixedly mounted in a single rigid and massive body 4, rigidly attached to the bag 1.

  • the housing 4 in the presented embodiment is attached to the material of the bag 1 using a disk rigidly fastened to the housing, so that during operation the acceleration sensor 2 does not change its position.
  • the transverse size of the case is selected on the one hand as maximum as possible to increase the accuracy of measurements, on the other hand, the thickness of the packing layer of the bag in the case of a metal case should not be less than 8-12 cm, so that when you hit it does not feel the presence of a case with a sensor.

  • SUBSTITUTE SHEET (RULE 26) On the basis of these data, the beginning and end of the impact are determined (impact time), the maximum value of the target acceleration during the impact, the maximum value of the impact force is calculated, as well as the kinetic energy of the bag after the impact (impact energy). All these data are displayed on display unit 5.
  • the sum of the impact energies is displayed — to determine the physical fitness level, or the sum of the impact forces (the so-called impact tonnage) —to determine the level of boxing skill. Since this mode is used when simulating a boxing match - on the display unit 5 the round number is displayed, the number of strikes inflicted and the time is counted down.
  • the simulator makes a sound similar to the sound of a gong.
  • This simulator allows you to not lose the accuracy of measurements even in the case of applying a quick series of strokes, when the bag sways and does not have time to take its original position.
  • This allows you to summarize the energy or power of strikes with high accuracy and correctly evaluate not only the physical form of an athlete, but also the level of boxing skill. For example, in the mode of determining the physical form of an athlete, a boxing match is imitated with 3 or 12 rounds of three minutes with a one-minute break. Summing up the energy of strokes during the fight, you can easily evaluate the athlete's physical form. Summing up the power of strikes (the so-called tonnage), one can also evaluate the level of boxing skill, since the skill of a boxer lies precisely in striking maximum strength with less energy.

Abstract

L'invention concerne une machine d'entraînement pour sports de combat et peut s'utiliser également comme attraction de divertissement. Elle permet d'obtenir des indicateurs de précision très élevée, avec des valeurs absolues, de la force de coups de boxeurs utilisant des sacs d'entraînement standards et ne nécessite pas d'étalonnage. La machine d'entraînement et dispositif de mesure de force comprend un sac d'entraînement (1), un capteur de vitesse (2) et une unité de traitement de signaux (3) montés fixes dans un boîtier uni et massif (4), fixé rigidement sur le sac (1). On peut utiliser en tant que capteur des accéléromètres intégraux volumiques en 3 D. Avec les sacs courts, on utilise un capteur unique disposé au centre géométrique de la zone des coups qui constituent en même temps le centre de gravité du sac. Avec les sacs longs, on utilise de façon optimale trois capteurs qui doivent être disposés verticalement le long d'un axe central du sac à une distance régulière inférieure ou égale au diamètre du sac. L'absence dans ce dispositif de parties mécaniques et l'absence d'étalonnage ainsi que l'utilisation de sacs d'entraînement de qualité élevée permettent de fabriquer un dispositif de fiabilité, technicité et précision élevées.
