Embodiment Construction

[0015] Referring to the accompanying drawings, the elastic rope falling test device of the present invention will be described in detail below.

[0016] Such as figure 1 with 2 As shown, the rope impact dynamic load test model device includes a rope 1, an impact mechanism 2, a tension sensor 3, a fixing mechanism 4, and a release mechanism 5. In addition to the above components, it also includes an elevated frame 6, which is a shelf located at a high place to facilitate the impact test operation of the impact mechanism 2 from a high place. Specifically, the fixing mechanism 4 is fixed on the elevated frame 6. The fixing mechanism is a connecting mechanism. The lower end of the fixing mechanism 4 is connected to the tension sensor 3. In order to detect the rope 1, the lower end of the tension sensor 3 is provided with a sleeve pin structure 31, and the two ends of the rope 1 The end is provided with a ring eye 11, which realizes that the ring eye 11 of the rope 1 is directly ...

Abstract

The invention relates to the field of ropes, in particular to an impact dynamic load test model device for a rope. The device comprises the rope, an impact mechanism, a tension sensor, a fixing mechanism and a release mechanism, wherein the tension sensor is arranged at the lower end of the fixing mechanism, the lower end of the tension sensor is connected to the rope, the lower end of the rope isconnected to the impact mechanism, the release mechanism can release the impact mechanism, the fixing mechanism and the release mechanism are both arranged on an elevated frame, and the release mechanism is fixed on the elevated frame through an initial fixing rope. The device has the advantages that the design is scientific and ingenious, workers can conveniently and intuitively detect the impact coefficient of the rope, a low-speed impact dynamic load simulation test can be carried out, so that the capacity of the structure for bearing low-speed and large-impact loads is verified, and the response characteristic of the structure under the low-speed impact load is obtained; and the standard for a novel impact experiment is provided, the test and operation of the workers in the field arefacilitated, and the device has the progressiveness and the instructive property in the field.

Description

technical field [0001] The invention relates to the field of ropes, in particular to a rope shock dynamic load test model device. Background technique [0002] In the field of aerospace technology, the return capsule needs to open the parachute to reduce the speed during the process of entering the atmosphere. However, at the moment of opening the parachute, the return capsule bears the transient impact force of opening the parachute, which causes an instant impact force on the astronauts in the return capsule. For scientific research, technicians use relevant simulation experiments to conduct relevant experiments on the transient impact of the return capsule. The above process is fixed by a rope, which has strict requirements and must undergo relevant verification, and the test generates the required maximum dynamic load within a certain time pulse. [0003] At present, there is no detection device for the above schemes, especially the low-speed impact dynamic load simula...
