To install the gas spring on the gas spring fatigue testing machine, follow these steps: First, position the gas spring piston rod downwards. Next, use the connectors at both ends to vertically install it on the machine.
In the first cycle of starting the machine, make a note of the opening force and starting force. Then, in the second cycle, record the extension force (Fl) and compression force (Fz, F3, F4).
After gathering these measurements, you can calculate the gas spring's nominal force, dynamic friction force, and spring force ratio.
By rearranging the original content and providing similar instructions, you can effectively complete the installation process and collect the required data for analysis.
To examine the locking force of rigid locking gas springs, they should be firmly locked in the extended position. The testing machine used for gas spring life testing operates at a measuring speed of 2mm/min. The locking force value is determined by applying an axial compression force that results in a 1mm displacement of the piston rod. This force is crucial in evaluating the performance of the gas springs and ensuring their effectiveness. By rearranging the provided information, a highly similar content can be generated while maintaining the original text's essence.
To ensure optimal performance, it is crucial to subject the elastically locked gas spring to a thorough testing process. This entails conducting 3 cycles of testing under realistic working conditions, followed by locking the gas spring at the midpoint of its stroke. In order to accurately measure the lifespan of the gas spring, a gas spring life testing machine with a measuring speed of 8mm/min is utilized. It should be noted that the axial compression force required to move the piston rod by 4mm is considered the locking force value. This stringent testing methodology guarantees that the gas spring meets the desired standards and functions efficiently in its intended application.
Gas spring life test:
The test method for evaluating the storage performance of a gas spring under high and low temperatures involves initial testing, followed by clamping the gas spring onto a specialized life testing machine. This testing machine then subjects the gas spring to cycles that simulate real working conditions, with a frequency of 10-16 times per minute. It is important to note that the temperature of the gas spring's cylinder barrel must not exceed 50℃ throughout the entire testing process.
Upon completing 10,000 cycles, it is imperative to evaluate the force performance using the designated test method. Once this is done, the actual values must align with the given criteria after 30,000 cycles.
The sealing performance of a gas spring's control valve is crucial for locking the piston rod in any position. This means that the piston must have optimal sealing qualities when the valve is closed, ensuring stability and security.
The gas bomb must successfully endure high and low temperature storage performance tests, proving its resilience. Additionally, it should be able to withstand 3,000 cycle life tests, with the nominal force decreasing by no more than 10% after the completion of the test.
