The tilt and sway test bench is mainly used for tilt and sway tests. Tilt and sway are a basic environment for mechanical, electrical, and electronic products installed on water equipment (including ships, seaplanes, and offshore oil exploration platforms). All types of mechanical, electrical, and electronic products installed on water equipment must withstand the effects of this environment. In addition to the tilt and sway on ships, products with high requirements for installation accuracy, working accuracy, and electronic instrument errors in other tilt and sway environments must undergo tilt and sway tests.

Main components and working principle of tilt and swing test bench
Main components:
1. Platform structure: It includes a frame, a table and a decoupling mechanism. The decoupling mechanism adopts a cross-axis structure with multiple degrees of freedom rotation connection to ensure that the test bench remains stable during tilting and swaying.
2. Counterweight device: Multiple counterweight blocks are connected by suspension cables and arranged in the up and down directions. The suspension cables are detachable, allowing users to adjust the quality and quantity of the counterweights according to test requirements. Each counterweight block has a cavity for coiling the suspension cable to achieve the switching between the suspended state and the grounded state.
3. Actuator: Multiple actuators that can drive the table in the up and down directions, and their upper ends are rotatably connected to the table. The output force of the actuator is relatively small because the test bench can automatically balance during movement.
4. Control system: The tilt and swaying state of the test bench is monitored by the intelligent control system, and the position and quality of the counterweight blocks are adjusted in real time to keep the system self-balanced. Users can set test parameters as needed.
Working principle:
When the test bench is in a horizontal balance state, the table is in a horizontal position. At least a part of the counterweight block in each counterweight device is in a suspended state, and the self-balancing state is achieved through the action of the suspension cable.
During the test, the control system adjusts the position of the suspension cable in real time according to the table position and test parameters to change the mass distribution of the counterweight block. This enables the test bench to automatically balance the forces caused by the tilt and sway of the test piece, thereby reducing the output force of the actuator and improving the test efficiency.
Tilt-sway test bench standard
The tilt-sway test bench standard is a specification formulated to ensure the accuracy and reliability of the test and to ensure the comparability of the test results. The following are general standards for tilt-sway tests:
1. Test purpose and scope: clarify the purpose and scope of the test, such as evaluating the stability of the product during transportation by ship, aircraft or vehicle.
2. Test equipment and conditions: describe in detail the equipment and conditions required for the test, including the test bench, test angle, vibration frequency, etc. Ensure the stability and repeatability of the test equipment.
3. Sample preparation: explain the selection and preparation methods of the samples, ensure that the samples meet the test requirements, and eliminate possible influencing factors.
4. Test steps: describe the specific steps of the test step by step, including placing the sample on the test device, setting the test conditions, starting the test, etc.
5. Data collection and analysis: explain the data types and collection methods required to be collected during the test, and give the steps and methods of data analysis.
6. Result evaluation: give evaluation criteria based on the test results, such as judging whether the sample passes the test, evaluating the stability of the sample, etc.
7. Safety precautions: remind test personnel of safety precautions that need to be paid attention to during the test to ensure the safety of the test.
8. Records and reports: require test personnel to record key information during the test in detail and write a test report for subsequent analysis and reference.
Maintenance recommendations:
1. Daily cleaning:
Regularly wipe the surface of the tilting swing table with a clean soft cloth to remove dust and stains. Avoid using rough cloth or brushes to avoid scratching the surface. At the same time, avoid using corrosive cleaners to avoid damaging the surface coating or material of the operating table.
2. Regular inspection:
- Electrical connection: If the tilting swing table is equipped with electrical components or control systems, the electrical connections should be checked regularly to see if they are firm and if they are loose or falling off.
- Structural stability: Regularly check the structural stability of the operating table, including the table top, bracket and base, to ensure that there is no deformation, looseness or damage.
3. Professional maintenance:
For tilting swing tables equipped with automated control systems or precision instruments, it is recommended to hire professionals for maintenance and maintenance. According to the frequency of use of the operating table and the working environment, a regular maintenance plan should be formulated, including cleaning, lubrication, tightening and debugging.
4. Avoid overloading:
During use, avoid placing heavy objects on the tilting swing table to avoid exceeding its load-bearing capacity and causing structural damage.
5. Keep dry:
Keep the operating table dry as much as possible to avoid prolonged exposure to moisture or soaking in water. For humid environments, dehumidification measures can be taken.
6. Regularly replace wearing parts:
For wearing parts such as electrical switches and buttons, their wear should be checked regularly and replaced in time.
7. Power-off maintenance:
When performing maintenance or repairs, be sure to disconnect the power supply first to ensure safety.
