Description

technical field [0001] The invention belongs to the technical field of mechanical environment experiment measurement, and in particular relates to a horizontal shock response spectrum measurement device. Background technique [0002] Because the impact movement will bring certain damage and destruction to the equipment, in turn, people need to study the nature and harsh conditions of the impact environment in which the equipment is located, and check the impact resistance of the equipment through environmental simulation experiments to improve the impact resistance of the equipment. Shock response spectrum is generally an important concept widely used in engineering. The International Electrotechnical Commission (IEC), the technical committees of the International Organization for Standardization (ISO) and China's national standards have all used the shock spectrum as one of the methods for specifying the shock environment. Therefore, the shock spectrum is the analysis basi...

Problems solved by technology

[0003] At present, the devices for measuring the shock response spectrum of equipment mainly include pendulum-type impact test equipment and free-fall impact test equipment. After the device to be tested is raised to a predetermined height, it is free-fall impacted to detect the shock response spectrum. The volume of the device detected by this free-fall impact test device is limited, and some devices are not allowed to change the placement position at will, so the scope of application is small. In addition , due to the existence of uncertain factors during the drop process of the test bench and the device to be tested, there will be no contact with the shock response spectrum detection device, so that the detection of the shock response spectrum cannot be realized; although the pendulum impact test device can better simulate the shock environment , so that the impact can meet the transient process of unsteady state, but the structure of this pendulum impact test device is more complicated, the cost is high, the space occupied is large, and the impact excitation is not easy to control; in addition, the pendulum impact test device and free fall The impact test device realizes oblique impact and vertical impact, and cannot realize horizontal impact test; moreover, the current pendulum impact test device and free fall impact test device can only realize the detection of the response spectrum, but cannot realize the detection of the shock spectrum. detection
