Description

Bow Shooting Simulation System

The present invention relates to a system for measuring shooting power and inclination of a bow when shooting an arrow and using the same to simulate a trajectory of an arrow shot by a bow in a three-dimensional virtual space.

In addition, the present invention relates to a system for calculating the accuracy of an arrow shot toward a target provided in a three-dimensional virtual space by simulation.

Bows such as bows, archery, and crossbows are known as weapons, and in modern times, they are widely known for their accuracy in shooting off targets. Archery, in particular, is a sport that requires more sophistication because it is affected by the slight changes in the wind as well as the force on the bow and arrow.

1 is a perspective view showing the configuration of a general prefabricated bow used in archery. The riser 100 is a structure located at the center of the bow and includes a grip 160, an arrow rest 150, and the like. The handle 160 is a portion which is held by the hand to support the bow when the bow string 290 is pulled, and the arrow bearing 150 supports the arrow until the arrow leaves the bow. Cushion Plunger (Cushion Plunger) may be added to the arrow bearing 150 to allow the bow to move lightly until the arrow leaves the bow after placing the bow 290. In addition, a clicker may be mounted around the arrow support 150 of the riser 100 to make the arrow move backwards, and the clicker extension may be mounted so that the clicker can be mounted. System) may be provided in the riser 100.

The upper and lower portions of the riser 100 are coupled to the wing (limb) 200 having elasticity, the riser 100 constitutes a wing coupling portion 110, the wing 200 is a riser coupling portion 210 It can be configured to be easily combined with each other. In the wing 200, the riser coupling part 210 is provided with an archer 250 capable of hanging the bow 290 at the opposite end of the one end provided with. Hang bows 290 on the bow 250 provided at each end of the wing 200 connected to the top and bottom of the riser 100 to form a prefabricated bow. These prefabricated bows have the advantage of being easy to remove, reducing the space required for movement and storage, and maintaining the elasticity of the bow that generates shooting power of the arrow.

Thus, a tiller 300 is used to adjust the degree of adhesion between the riser 100 and the wing 200 coupled thereto. The tiller 300 is screwed to the riser 100, and the tip of the riser coupling portion 210 of the wing 200 coupled to the upper and lower portions of the riser 100 is caught by the tiller 300 and the tiller ( Tighten or loosen 300 to adjust the adhesion of the wing 200 and riser 100. When the tiller 300 is tightened, the contact between the wing 200 and the riser 100 is increased, and the elasticity of the wing 200 is adjusted. The tiller 300 coupled to the upper wing 200 and the lower wing 200 is adjusted. It can also be used to adjust the zero point in the up and down direction by adjusting each of them.

FIG. 2 shows an assembly example in which the prefabricated bow of FIG. 1 is coupled. The sliding coupling concave-convex 215 provided in the riser coupling portion 210 of the blade 200 is slid into the wing coupling portion 110 provided in the riser 100 to engage with the riser 100. The tiller 300 is screwed to the riser 100, and the tiller coupling groove 212 provided at one end of the wing 200 is tilted as the riser coupling part 210 of the wing 200 is slid and coupled. Surrounding the 300 and is assembled while the wing 200 is fitted between the engaging members provided in the tiller 300. By tightening or releasing the tiller 300, it is possible to adjust the degree of adhesion of the riser 100 screwed to the wing 200 caught in the locking member. In order to prevent the screw of the tiller 300 from rotating due to the vibration of the bow shooting, a screw inserted into the tiller 300 may be further inserted into the tip of the threader 300 to fix the tiller 300. .

3 is a cross-sectional view showing the configuration of a prefabricated bow. As described above with reference to FIGS. 1 and 2, the sliding coupling concave-convex 215 provided in the riser coupling part 210 of the blade 200 may be slid to be coupled to the blade 200 and the riser 100.

You may. In this case, the sliding coupling concave-convex 215 of the wing 200 is coupled to the sliding hole 119 provided in the bracket 110 is coupled. In addition, the fixing position of the bracket 111 is variable so that the center of the wing 200 coupled to the riser 100 may be adjusted.

On the other hand, to measure the magnitude of the force pulling the bow strike 290 in order to measure the shooting power of the bow, in order to measure the tension caught on the bow 290, the tension sensor is directly connected to the bow 290 In general, even if not directly connected, the deformation and vibration of the bow and bow demonstration 290 due to the shooting of the bow is transmitted directly to the sensor has a disadvantage in reducing the durability by causing damage to the sensor.

In the actual shooting of the bow, the bow moves in a complex manner under the action of force in various forms. In addition, since the shooting power of the bow is not determined only by the tension applied to the bow strike 290, simply using the measured tension as the shooting power of the bow increases the error in predicting the flight trajectory of the fired arrow. Cause.

In addition, even in the method of measuring the speed of the arrow fired by the roller in contact with the arrow, there is a disadvantage in that energy loss due to friction of the roller for measuring the arrow is generated, which makes it difficult to measure accurate shooting power.

As such, the simulation of judging the hit rate of the arrow by the tension measured from the bow has a disadvantage in that the realism is weak and the accuracy thereof is also lowered.
