1、 Technical principles

The hydraulic drilling vibration hammer test bench is based on hydraulic transmission and control technology, and applies dynamic loads to the hammer by simulating the stretching, compression, and twisting actions of the drill string. The core principles include:

1. Hydraulic loading systemUsing high-pressure hydraulic oil to drive the piston, generating axial or torsional force, simulating the stress state of the drill string.
2. Dynamic Control TechnologyAdopting an electro-hydraulic servo control system to achieve precise adjustment of loading force, frequency, and displacement, simulating downhole stuck drilling, encountering obstacles, and other working conditions.
3. Data Collection and AnalysisIntegrate high-precision sensors (such as force sensors and displacement sensors), monitor the response parameters of the shock absorber in real time, and analyze its performance indicators through software systems.

2、 Core functions

1. Shock force test：
   • Measure the maximum impact force and energy release characteristics of the shock absorber under different operating conditions.
   • Evaluate the attenuation law of shock force and verify its long-term reliability.
2. Durability Test：
   • Simulate high-frequency vibration operations to test the fatigue life and structural strength of the shock absorber.
   • Verify the durability of key components such as seals and pistons.
3. Environmental adaptability testing：
   • Simulate underground environments such as high temperature, high pressure, and mud corrosion to evaluate the environmental adaptability of the shaker.
4. Fault simulation and diagnosis：
   • Set up fault scenarios such as drill jamming and mud blockage, and test the emergency response capability of the shaker.
   • Identify potential fault points through data analysis and guide product optimization.

3、 Application scenarios

1. Product development and validation：
   • Used for the design verification, optimization of structural parameters and control strategies of a new hydraulic drilling vibration hammer.
2. Quality Inspection and Certification：
   • According to industry standards (such as API specifications), the shock absorber undergoes factory testing to ensure that the product meets performance requirements.
3. Teaching and Training：
   • Simulate actual working conditions, provide operational training for drilling engineers, and enhance emergency response capabilities.
