How does the design and material selection of Non-Suspension Shock Absorbers affect performance?

The design and material selection of Non-Suspension Shock Absorbers have a crucial impact on their performance. The core function of a shock absorber is to absorb and reduce the impact forces transmitted in a mechanical system or vehicle, thereby improving the stability and comfort of the system. Through reasonable design and appropriate material selection, the shock absorption efficiency, durability and adaptability of the shock absorber can be significantly improved. The following is an analysis of the specific impact of design and material selection on the performance of non-suspension shock absorbers:

Impact of design on performance
structural design
The structural design of non-suspension shock absorbers determines their shock absorption effect, durability and installation adaptability. Common design forms include single-cylinder type, double-cylinder type, hydraulic type, pneumatic type, etc. Shock absorbers of different designs have different performances:
Monotube design: Typically used in applications requiring higher shock absorption and long-term stability. The monotube design provides better heat dissipation and reduces oil and gas separation, providing more consistent shock absorption. Because the monotube is a simpler design, it is generally lighter in structure and weight, making it suitable for environments where space is limited.
Dual-tube design: This design is more complex in structure, but it can provide good shock absorption over a wide range. The advantage of the double-cylinder design is that it can separate oil and gas to avoid the attenuation of shock absorption efficiency caused by gas foaming. It is often used in applications requiring stable performance and high durability.
Hydraulic and pneumatic shock absorbers: Hydraulic shock absorbers use fluid as the damping medium, while pneumatic shock absorbers use gas (usually nitrogen) to adjust the shock absorption effect. Pneumatic shock absorbers are often used for high-frequency vibration control, while hydraulic shock absorbers can provide stronger damping effects and are suitable for heavy-duty industrial applications.
Other factors in the design, such as the size and shape of the piston, how the damping system is adjusted, the design of the sealing system, etc., also directly affect the performance of the shock absorber. Proper design can maintain the working stability and efficiency of the shock absorber under different load and impact conditions.
Damping characteristic adjustment

Many non-suspension shock absorber designs include adjustable damping features that allow the shock absorber performance to be tailored to different application needs. There are many types of adjustment methods, such as manual adjustment, electronic adjustment, hydraulic adjustment, etc.:
Manual adjustment: Adjust the damping force of the shock absorber through an external knob or valve, suitable for some equipment that requires regular performance adjustment.
Electronic adjustment: Utilizes sensors and electronic control units to automatically adjust the performance of the shock absorber in real time based on load or vibration amplitude. This type of adjustment is often used in high-end vehicles or complex machinery.
Hydraulic adjustment: Changing the damping effect by adjusting the flow of hydraulic oil, which is widely used in engineering machinery and some industrial equipment.
The adjustment of damping is crucial to the shock absorption effect. Appropriate damping can effectively alleviate the impact, while too high or too low damping may cause the shock absorber to work unstable or even be damaged.
Impact of Material Selection on Performance
Shock absorber housing material
The shock absorber's shell material not only affects its strength and durability, but also determines the shock absorber's overall weight and corrosion resistance. Common shell materials include steel, aluminum alloy, stainless steel, etc.

Steel: Steel housings have high strength and durability and can withstand large impacts, making them suitable for heavy-duty and high-impact applications. However, steel may be affected by corrosion and require additional anti-corrosion treatments such as galvanizing or painting.

Aluminum alloy: Aluminum alloy housings are lighter and suitable for applications that reduce the weight of the overall device, especially in automobiles or aircraft. Aluminum alloy has good corrosion resistance and is suitable for use in harsh environments, but its strength is relatively low and is suitable for applications with light or medium loads.

Stainless steel: Stainless steel material has excellent corrosion resistance and is suitable for use in highly chemically corrosive or high-humidity environments. Although stainless steel is more expensive than aluminum alloys and steel, its excellent corrosion resistance and high temperature resistance make it the first choice for many industrial applications.

The design and material selection of a non-suspension shock absorber have a profound impact on its performance. By carefully selecting the right materials and design solutions, you can ensure that the shock absorber provides efficient shock absorption, long service life and excellent durability in different application environments.
