Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-3, the present invention provides a technical solution: the utility model provides an experimental apparatus is strikeed to electron human body scale side, includes support 1, and the inner wall top of support 1 is provided with pivot 2 through connecting the installation piece, cup joints in pivot 2 and is provided with pendulum rod 3, and the bottom of pendulum rod 3 is provided with pendulum 301, and the rear end face bottom of support 1 is provided with base 5, and the top of base 5 is provided with electronic scale 4.
Wherein: the rear end face of the pendulum bob 301 corresponds to the center of the top glass between the support legs of the electronic scale 4, so that the electronic scale 4 can be conveniently detected, the weight of the pendulum bob 301 is set to be 50 pounds, the weight of the pendulum bob 301 is limited, and data can be conveniently calculated during experiments;
the rear end face of the pendulum bob 301 is provided with a conical rubber contact block, and the conical rubber contact block is made of rubber with the Shore hardness of 70HA, so that the electronic scale 4 is prevented from being broken through impact due to the fact that the pendulum bob 301 is too hard;
the base 5 is an L-shaped base, and the bottom and the rear end face of the electronic scale 4 are both attached to the base 5, so that the electronic scale 4 is fixed conveniently;
support 1 sets up to "door" type support, and support 1 and ground vertical, is convenient for install electronic scale 4 and carry out the detection of experiment.
The working principle is as follows: the 4 lateral impact experimental devices of electronic scale want to realize that four sides of electronic scale 4 are all strikeed once by impact energy for 113J pendulum 301, and the striking position is in the top glass center part between 4 supporting legs of electronic scale, pendulum 301 weight 50 pounds, and striking speed 3.15 meters per second, and pendulum 301 and 4 contact position of electronic scale require the rubber that shore hardness is 70HA, and 4 lateral impact experimental devices of electronic scale technical parameter calculation:
it is known that: punch quality: m is 50 pounds, impact energy: E113J;
unknown: the length of the swing rod 3 and the initial angle of the swing rod 3;
unit conversion: 50 pounds of 0.4534kg of 50 kg of 22.65 kg;
calculating the length of the swing rod 3:
setting: the swing rod 3 is arranged in the direction vertical to the ground
Length of the swing link 3:
E＝mgh
h＝0.505m
and (3) impact speed verification:
V＝3.15m/s
according to the test requirements, by utilizing the principle of conservation of kinetic energy, a 50-pound pendulum bob 301 is connected by a light aluminum alloy connecting rod with the length of 0.505m, is fixed on a support 1 vertical to the ground and is locked by a brake pin, an electronic scale 4 is fixed on a base 5, and after the brake pin is pulled open instantaneously, the potential energy of the pendulum bob 301 is converted into kinetic energy, namely the electronic scale 4 is impacted laterally at the speed of 3.15m/s, so that the electronic scale is impacted by 113J energy.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
