Abstract
The invention relates to a floor vibration excitation signal generating device for furniture stability detection. The floor vibration excitation signal generating device for furniture stability detection solves the problem that at present, a vibration source which can lead furniture on a composite floor to vibrate and shake regularly and accurately does not exist. The floor vibration excitation signal generating device is used for furniture detection and comprises a motor, a cam, a suspension rod, a support body, an elastic hammering body and a suspension rope. A motor shaft of the motor is connected with a wheel disc shaft of the cam so as to enable the motor and the cam to rotate coaxially, one end of the suspension rod is hinged to the top end of the support body, the other end of the suspension rod is connected with the upper end of the suspension rope, the lower end of the suspension rope is connected with the elastic hammering body, the cam is in the shape of a disc, the outer edge of the disc-shaped cam serves as a working surface, and a rod body of the suspension rod is located above the cam and pressed on the working surface of the cam.
Description
Technical field
The present invention relates to a kind of floor vibration pumping signal generating means for detection of furniture stability.
Background technology
It is reported, between 1990-2007, the incident of injury that causes is toppled over up to 14700 by furniture every year on average by the U.S., and majority occurs in it 6 years old following children.China does not still have this type of statistics, but almost can say for certain that accident rate is higher than the U.S..
Stability is to evaluate the important indicator of furnature construction security.The underproof furniture of stability may bring the loss of personal injury or property to daily life.When furniture be placed on indoor with the composite floor board of cushion on time, often can cause rocking in furniture use procedure because of the elastic reaction of underfloor padded coaming, this degree of rocking can be different because of the difference of fender.For example, when having people in furniture walking around, when jogging or beating, all can produce impact load effect to floor, indirectly cause the vibration of furniture to rock, can make furniture produce the wild effect while using.
While using on the composite floor board with fender according to furniture, may produce the phenomenon that vibration is rocked.Take certain automation means, furniture is changed in dynamic test process to the data acquisition of physical quantity (as acceleration, speed, displacement), the data analysis that experiment is recorded is processed, finally data are carried out to correlation analysis, thereby can evaluate the feasibility of the dynamic evaluation method of furniture.But also do not have to make the furniture on composite floor board to produce the vibration source that vibration regular, accuracy is rocked at present.
Summary of the invention
The object of this invention is to provide a kind of floor vibration pumping signal generation device for furniture Detection of Stability, to solve the furniture that does not also have at present to make on composite floor board, produce the problem of the vibration source that vibration regular, accuracy rocks.It comprises motor 1, cam 2, suspension rod 3, bearing body 4, elasticity hammering body 5 and outstanding rope 6, the motor shaft of motor 1 is connected so that the two coaxial rotating with the wheel disc axle of cam 2, one end of suspension rod 3 is hinged on the top of bearing body 4, the other end of suspension rod 3 connects the upper end of outstanding rope 6, the lower end of outstanding rope 6 connects elasticity hammering body 5, cam 2 is disk cam, and the outer rim of disk cam is working face, and the body of rod of suspension rod 3 is positioned at the top of cam 2 and is pressed on the working face of cam 2.
Apparatus of the present invention Elastic hammering body 5 is placed in to the top on floor, start motor 1, cam 2 rotations, because the body of rod of suspension rod 3 is pressed on the working face of cam 2, suspension rod 3, along with the cyclically-varying of the impulse stroke of cam 2, swings around bearing body 4, and the elasticity hammering body 5 of outstanding rope 6 lower ends is hammering floor periodically, make the furniture on floor produce regular rocking, thereby produced the pumping signal for studying and detecting.Because sort signal is to be produced by mechanical device, its vibration regularity is both fixing also can be adjusted, and is suitable as very much the vibration source that the vibration of research furniture is rocked.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.Fig. 2 is the top view of Fig. 1, and Fig. 3 is the structural representation of embodiment three Elastic hammering bodies 5.
The specific embodiment
The specific embodiment one: illustrate present embodiment below in conjunction with Fig. 1 and 2.Present embodiment comprises motor 1, cam 2, suspension rod 3, bearing body 4, elasticity hammering body 5 and outstanding rope 6, the motor shaft of motor 1 is connected so that the two coaxial rotating with the wheel disc axle of cam 2, one end of suspension rod 3 is hinged on the top of bearing body 4, the other end of suspension rod 3 connects the upper end of outstanding rope 6, the lower end of outstanding rope 6 connects elasticity hammering body 5, cam 2 is disk cam, and the outer rim of disk cam is working face, and the body of rod of suspension rod 3 is positioned at the top of cam 2 and is pressed on the working face of cam 2.
The specific embodiment two: illustrate present embodiment below in conjunction with Fig. 2.Present embodiment has increased frequency converter 7 with respect to embodiment one, and frequency converter 7 is arranged on the power supply end of motor 1 to control the output speed of motor 1.So arrange, can adjust easily the hammering frequency of the present invention to floor.
The specific embodiment three: illustrate present embodiment below in conjunction with Fig. 3.Present embodiment Elastic hammering body 5 is the inner rubber ring that is filled with sand 5-1.So arrange, elasticity and weight meet the demands and cost compare low, rubber ring can directly be used the repackings such as waste tire of automobile.
The specific embodiment four: illustrate present embodiment below in conjunction with Fig. 1.Present embodiment has increased elastomer block 8 and vertical rod 9 with respect to embodiment one, and elastomer block 8 is arranged on the top of vertical rod 9 and is positioned at the below of suspension rod 3.So arrange, when suspension rod 3 plunks down from cam 2 the highest travel position, by elastomer block 8, accept suspension rod 3, avoid directly slapping against on the working face of cam 2, cause the damage of cam 2 or suspension rod 3.
