Finally, the waveform generator 13 is set to output corresponding waveform data, so that the preparation work of the impact test is completed.
The operation of the impact testing system of the present invention is described below.
During the test, the releaser 22 releases the equipment mounting rack 31 according to the control signal, the equipment mounting rack 31 and the impact test equipment slide along the slide rail 14 under the self gravity and the elasticity of the tension rope 4, and impact the waveform generator 13, and the waveform generator 13 outputs the corresponding impact waveform.
The following illustrates the principle of operation and uses the data to illustrate the amount of lift of the present invention on the order of the impact load compared to conventional impact testing systems.
The conventional impact testing system, impact test and equipment mounting 31, when hitting the waveform generator 13, carries a kinetic energy of mgh. Wherein m is the sum of the weights of the impact test equipment and the equipment mounting bracket 31; g is a gravity coefficient; h is the height of the center of gravity of the entire impact test apparatus and apparatus mounting frame 31 from the impact surface of the waveform generator 13.
In the impact test system provided by the utility model, when the impact test equipment and the equipment mounting rack 31 integrally impact the waveform generator 13, the carried kinetic energy is mgh +1/2kx2. Wherein m is the sum of the weights of the impact test equipment and the equipment mounting bracket 31; g is a gravity coefficient; h is the height from the gravity center position of the whole impact test equipment and the equipment mounting frame 31 to the impact surface of the waveform generator 13; k is the elastic coefficient of the tension rope 4; x is the deformed length of the tensile cord 4.
It can be seen that the present invention provides a comparative impact testing system under the same conditions as the conventional impact testing systemIncrease kinetic energy of the impact test system by 1/2kx2。
In the present invention, the kinetic energy carried by the impact testing apparatus when it strikes the waveform generator 13 is mainly related to the following parameters: the number of tensile cords 4, the spring constant of the tensile cords 4, the original length of the tensile cords 4, the initial height of the equipment mounting bracket 31, and the like.
When the magnitude of the impact load required by the test is small, the tensile rope 4 in the impact test system can be removed, and the initial height of the equipment mounting frame 31 is reduced.
When the impact load magnitude required by the test is larger, the two ends of the tensile rope 4 can be respectively fixed on the equipment mounting frame 31 and the base 11, the number of the tensile rope 4 is increased, the elasticity coefficient of the tensile rope 4 is increased, and the original length of the tensile rope 4 is reduced, so that the requirement is met.
According to the impact test system provided by the embodiment of the utility model, the elastic potential energy of the elastic rope and the gravitational potential energy of the impact test equipment are converted into kinetic energy, so that a larger impact test load magnitude is realized. Meanwhile, the test requirements of different load magnitude levels are met by adjusting the number of the elastic ropes, the elastic coefficient, the original length, the falling height and other parameters.
