How to ensure that Non-Suspension Shock Absorbers can withstand impacts of different intensities during the design process?

Ensuring that non-suspension shock absorbers can withstand impact forces of varying intensities requires a comprehensive consideration of multiple factors during the design process to achieve their efficient shock absorption function. Here are some key design considerations and technical solutions:

1. Load analysis and impact force calculation
Understand the impact characteristics of the working environment: When designing a non-suspension shock absorber, you first need to have a deep understanding of the working environment in which it will be used. For example, the equipment may be subjected to different types of impacts, including short-term strong impacts or long-term light impacts. Through simulation or experiments, the maximum impact force and frequency of impacts to the equipment can be predicted.

Dynamic load and static load evaluation: Evaluate possible dynamic loads (such as high-frequency vibration, rapid impact) and static loads (such as pressure applied for a long time) to ensure that the shock absorber can effectively absorb impacts and remain stable in both cases.

Impact testing: In the early stages of the design, performing impact tests of different intensities can help predict and evaluate the shock absorber's impact resistance, thereby ensuring that the design can withstand impacts of varying intensities.

2. Material selection and strength design
High-strength and toughness materials: The key is to choose materials with good impact resistance. Common shock absorber materials include**steel alloys, stainless steel, aluminum alloys, special plastics (such as nylon, polyurethane), etc. These materials have high tensile strength and impact strength. According to different impact strength requirements, suitable materials can be selected.

Fatigue resistance and wear resistance: In addition to impact strength, the fatigue resistance and wear resistance of materials are also important parts of the design. After long-term impact or vibration loads, materials may suffer fatigue damage, so it is necessary to select materials with strong fatigue resistance to ensure that the shock absorber maintains stable performance during repeated use.

3. Internal structure and working principle design
Hydraulic or pneumatic system design: The main working principle of non-suspension shock absorbers usually involves hydraulic or pneumatic systems. Reasonable cylinder volume, piston design and damping adjustment mechanism can effectively absorb impact forces of different intensities. For example, through an adjustable damping system, the shock absorber can adjust the intensity of shock absorption according to different impact forces to adapt to various working conditions.

Pressure release mechanism: The pressure release function inside the shock absorber should be considered during design. When the impact force exceeds the preset range, a certain overflow valve or pressure regulation system should be designed to prevent damage to the shock absorber caused by excessive pressure.

4. Optimization of shock absorber size and stiffness
Stiffness matching: When designing a shock absorber, choose the appropriate stiffness based on the expected load and impact strength. If the stiffness is too high, the shock absorber will find it difficult to effectively absorb the impact; while if the stiffness is too low, the shock absorption effect may be insufficient. Through simulation analysis and testing, the most suitable stiffness is determined to ensure the best shock absorption effect under different impact conditions.

Spring stiffness and elastic material selection: Non-suspension shock absorbers are often equipped with springs or elastic materials to provide the necessary rebound and shock absorption capabilities. The design of the spring should take into account the range of working load changes to ensure that it will not permanently deform or fail when subjected to force.

5. Multi-stage shock absorption structure design
Graded shock absorption: For applications with strong impact, designing a multi-stage shock absorption structure can effectively absorb impact forces of different intensities. For example, the shock absorber can be designed as a two-stage or multi-stage shock absorption structure: the primary stage quickly absorbs most of the impact force, and the secondary stage continues to absorb the remaining impact. This structure ensures that the shock absorber remains effective under different impact intensities.

Progressive damping system: The progressive damping system can gradually increase the damping value according to the size of the impact force to adapt to different impact intensities. For example, under lighter impacts, the shock absorber provides low damping, while under stronger impacts, the system provides higher damping effect.

6. Simulation and simulation analysis
Finite element analysis (FEA): By using advanced simulation technologies such as finite element analysis (FEA), the stress, deformation and failure mode of the shock absorber under various impact forces can be predicted during the design stage. By simulating impacts of different intensities, designers can adjust the structural design in advance to ensure that the shock absorber can withstand impacts of different intensities in actual applications.

Fatigue analysis and life prediction: Fatigue analysis of non-suspension shock absorbers is performed to evaluate their performance degradation process under long-term impact and vibration. This helps to design shock absorbers that can maintain good performance after multiple impacts.

7. Thermal management and temperature effects
The impact of temperature changes: The magnitude of the impact force and the change in temperature may interact with each other. In high temperature environments, the performance of hydraulic oil or gas may change, so the impact of thermal expansion and temperature changes on shock absorber performance should be considered during design. Reasonable heat dissipation design and temperature control system can help shock absorbers maintain stable performance under various temperature conditions.

Thermal fatigue and thermal stress: The heat accumulation generated by the impact may affect the structure of the shock absorber, causing thermal fatigue or thermal deformation. When designing, it is necessary to consider how to effectively dissipate heat and the thermal stability of the material to avoid shock absorber failure due to excessive temperature.

8. Sealing and protection design
Dustproof and waterproof design: Non-suspension shock absorbers are often exposed to harsh environments, such as construction sites or vehicles. Therefore, an effective sealing system needs to be designed to prevent contaminants such as dust and moisture from entering the shock absorber. An efficient sealing system can ensure that the shock absorber maintains optimal performance under long-term high loads and impacts.

External protection structure: For components that may be subjected to external impact, an external protective shell is designed to prevent the impact from damaging the outside of the shock absorber. This is very necessary to increase the service life of the shock absorber and improve its impact resistance.

9. Maintenance and inspection in actual use
Regular inspection and maintenance: The maintainability of the shock absorber should be considered during design to ensure that it can be easily inspected and repaired after long-term use. Especially under high-intensity impact, the internal components of the shock absorber may be worn or damaged, so a simple inspection and replacement solution should be provided during design.

Health monitoring system: In high-impact applications, a health monitoring system can be equipped to monitor the working status and performance of the shock absorber in real time, detect potential faults in time, and avoid greater losses.

In order to ensure that non-suspension shock absorbers can withstand impact forces of different intensities, the design process needs to fully consider load analysis, material selection, structural design, stiffness matching, temperature control, sealing and other aspects. Through reasonable design optimization, simulation analysis and material selection, the shock absorber can maintain stable performance under impacts of different intensities and extend its service life.
