How to optimize the geometry of Non-Suspension Shock Absorbers to improve their performance and durability?

Optimizing the geometry of non-suspension shock absorbers is a key step to improve their performance and durability. Through reasonable design and improvement, the shock absorption efficiency, load capacity and service life of the shock absorber can be significantly enhanced. The following are specific optimization methods and implementation strategies:

Improve shock absorption efficiency
Optimize the fit between the piston rod and the cylinder
Adjust the gap: Appropriately reduce the gap between the piston rod and the inner wall of the cylinder to reduce oil leakage and improve the damping effect.
Improve seal design: Use high-performance sealing materials (such as fluororubber or polyurethane) and optimize the shape of the seal to ensure good sealing under high pressure and high temperature conditions.
Increase the complexity of the fluid channel
Design complex fluid channels (such as multi-porous and multi-cavity structures) on the piston to achieve more precise flow control and more efficient energy dissipation.
Introduce variable damping technology to adapt to different vibration frequencies by changing the opening and closing state of the fluid channel.
Optimize spring layout
Select the appropriate spring type (such as coil spring, leaf spring or pneumatic spring) according to the shock absorption requirements, and optimize its installation position and preload.
In some scenarios, dual or multi-spring systems can be used to provide a wider range of shock absorption capabilities.
Enhance load capacity
Increase effective area
Increase the effective area of ​​the piston to improve the shock absorber's ability to absorb impact loads.
At the same time, it is necessary to balance weight and volume to avoid affecting the compactness of the overall structure due to oversizing.
Strengthen the shell strength
Use high-strength materials (such as aluminum alloy, titanium alloy or composite materials) to manufacture the shell to withstand higher pressure and impact.
Add ribs or thick-walled areas in the shell design to improve deformation resistance.
Introduce auxiliary support structure
Add support frames or connectors to the outside of the shock absorber to disperse the load and reduce local stress concentration.
For large equipment, consider using a multi-point support design to further improve stability.
Extend service life
Improve wear resistance
Harden the surface of key components (such as piston rods and cylinder inner walls) (such as carburizing, nitriding or plating) to improve wear resistance and corrosion resistance.
Use self-lubricating materials (such as PTFE coatings) to reduce friction and reduce wear rate.
Optimize thermal management

Design an effective heat dissipation system (such as adding heat sinks or cooling channels) to prevent performance degradation or material aging due to overheating.
In high-temperature environments, choose materials with stronger heat resistance (such as high-temperature rubber or ceramic coating).
Simplify maintenance design
Provide detachable or modular design to facilitate users to regularly replace wearing parts (such as seals, oil).
Set monitoring devices (such as pressure sensors or temperature sensors) at key locations to monitor the status of the shock absorber in real time and detect potential problems in advance.
Improve environmental adaptability
Waterproof and dustproof design
Add a protective cover or sealing ring to the outside of the shock absorber to prevent dust, water vapor or other contaminants from entering the interior.
Use IP67/IP68 protection design to ensure the reliability of the shock absorber in harsh environments.
Anti-fatigue design
Optimize the geometric structure through finite element analysis (FEA), reduce stress concentration points, and improve fatigue resistance.
Use dynamic simulation technology to verify the rationality of the design at high vibration frequencies and make necessary adjustments.
Chemical corrosion resistance
For application scenarios that come into contact with chemical substances, choose corrosion-resistant materials (such as stainless steel or coated metals).
Use stable hydraulic oil or gas media inside the shock absorber to avoid performance degradation due to chemical reactions.

The performance and durability of non-suspension shock absorbers can be significantly improved by optimizing the geometry, selecting high-performance materials, and introducing advanced technologies. These improvements can not only meet the needs of different application scenarios, but also extend the service life of the equipment and reduce maintenance costs.
