Report on the fall of the flexible gate

Experimental principle

Due to its material and structural characteristics, the flexible gate has a certain flexibility and impact resistance, when subjected to external force, the flexible gate will be deformed, and resist the external force through the yield of the material and the absorption of energy, when the external force exceeds the bearing capacity of the gate, the gate may be damaged, this experiment studies its mechanical behavior under different conditions by simulating the process of the gate falling.

Experimental equipment and materials

1. Flexible door samples: several flexible door samples of different materials, specifications and structures.

2. Fall test device: including height-adjustable test bench, falling weight, data measuring instrument, etc.

3. Auxiliary tools: including fixtures, sensors, data acquisition systems, etc.

Experimental Procedure

1. Select the sample of the flexible gate and record its material, specification and structural information.

2. Build a fall test device and adjust the height of the test bench to ensure that the fall height meets the experimental requirements

3. Fix the sample of the flexible gate on the laboratory bench to ensure that it is firmly fixed.

4. Install sensors and data acquisition systems, and prepare to record experimental data.

5. Make the falling heavy object fall freely and hit the flexible door sample.

6. Observe the deformation, force and damage of the flexible door, and record the experimental phenomenon.

7. Repeat the experiment to change the conditions such as gate sample and fall height to obtain more data.

8. Analyze the experimental data and obtain the experimental results.

Experimental data analysis

Through experiments, we obtained the data of deformation, force and failure of flexible doors under different conditions, and the following is the analysis of the experimental data:

1. Deformation: In the process of falling, the flexible gate shows good deformation ability and can effectively absorb energy, and the deformation behavior of different materials and gate structures is different, but the overall trend is similar.

2. Force: Through the data recorded by the sensor, we can get the force of the flexible gate in the process of falling, and the results show that when the flexible gate is impacted, it will produce a large instantaneous impact force, and then the impact force gradually decreases.

3. Damage: In the experiment, some flexible door samples are damaged when subjected to greater impact force, and the failure forms include tearing, fracture, etc., through the analysis of the failure form, we can understand the impact resistance of the gate of different materials and structures.

4. Analysis of influencing factors: The experimental results show that the material, structure, size and falling height of the flexible gate have a significant impact on its mechanical properties.

Experimental results

With this experiment, we obtained the following results:

1. The flexible door has good deformation ability and impact resistance, and can effectively absorb energy.

2. The stress of the flexible door is related to factors such as material, structure, size and falling height.

3. When subjected to a large impact force, the flexible gate may be damaged, and the damage forms include tearing, breaking, etc.

4. Through the analysis of the experimental results, we can provide theoretical support for the design, manufacture and safe use of flexible gates.

The experimental results show that the flexible gate has good deformation ability and impact resistance, but it may be damaged when subjected to a large impact force, in practical application, the appropriate flexible door should be selected according to the specific situation, and pay attention to the safe use, this experiment provides theoretical support for the design, manufacture and safe use of the flexible gate.
