The 3D-dimensional vibrating table is usually excited by 6 sets (3 groups) of vibration motors. When the dual motors rotate in the opposite direction, the vertical vibration is the superposition of the two motors, and the vibration model is one-dimensional linear vibration; when the dual vibration motors rotate in the same direction or the single motor rotates, larger horizontal vibrations can be obtained. The model is a two-dimensional ellipse. During production, the operator can control the operation of the motors in different directions (X., y, z) to meet the filling and compaction requirements in different directions. Most three-dimensional vibrating tables can realize vibrations in three single directions of X, y, and z and compound directions of xy, XZ, and xyz in a certain combination and sequence.
In precision casting, automotive parts testing and material research, multi-directional composite vibration control is the core process to improve product quality. The three-dimensional vibration table has become a key device for simulating complex working conditions and achieving high-precision compaction with its 6 sets of vibration motor cooperative excitation system and multi-dimensional vibration mode switching technology. This article will deeply analyze how the device can meet the stringent requirements of modern industry for multi-dimensional vibration testing with 0.1mm amplitude accuracy and XYZ composite vibration mode from the dimensions of technical principles, core advantages, industry applications and intelligent upgrades.
1. Technical principle and vibration mode innovation
Based on the three-axis orthogonal vibration theory, the three-dimensional vibration table achieves multi-dimensional excitation breakthroughs through motor configuration control algorithm and composite trajectory generation technology:
6 sets of vibration motor coordination system
Dual motor reverse excitation: Two sets of vibration motors (power 7.5kW/set) are configured in the X/Y/Z axis, and the excitation force is superimposed to 80kN during reverse rotation, achieving one-dimensional linear vibration in the vertical direction (amplitude accuracy ±0.1mm);
Co-rotation mode: Single-axis dual motors run in the same direction to generate a horizontal elliptical trajectory (long axis 15mm, short axis 5mm), which is suitable for two-dimensional spreading and compaction of powder (density uniformity > 98%).
Single-axis independent control: X/Y/Z axis can be operated independently, the vibration frequency is adjustable from 5 to 60 Hz, and it is suitable for transport vibration simulation under ISO 13355 standard; Multi-axis timing superposition: XY/XZ/XYZ composite vibration (phase difference 0-360° can be set) can be realized through PLC programming, simulating multi-dimensional composite working conditions such as earthquake waves and wave impact. Intelligent feedback adjustment system:
Piezoelectric acceleration sensor monitors vibration parameters in real time (sampling rate 1kHz), dynamically corrects motor speed (accuracy ±1r/min);
Supports 8 waveform imports such as sine wave, random wave, shock wave, etc., and the waveform reproduction error is less than 3%
2. Core advantages and process value
Compared with the traditional uniaxial vibration table, the three-dimensional vibration table achieves multi-dimensional upgrades through multi-directional excitation flexible switching and load-bearing capacity breakthroughs:
Precision vibration performance
Sand mold compactness ≥85% (resin sand casting), casting porosity <0.3%, surface roughness optimized to Ra6.3μm;
Powder filling density uniformity increased by 40% (such as nanomaterials, refractory brick molding), porosity ≤1.5%.
Super load capacity:
The table can bear up to 8 tons (size 2m×3m), suitable for large specimen testing such as automobile chassis and spacecraft components;
The shock-absorbing spring group (rubber/composite spring) reduces the vibration transmission rate of the equipment to less than 5%, and the foundation requirements are reduced by 50%.
Intelligent production adaptation:
Electric adjustment of table height (stroke 0-300mm), seamless connection with assembly line conveying system (beat ≤30 seconds/piece);
Self-locking fixture module (pneumatic/hydraulic) ensures that the displacement of the test piece is less than 0.05mm
3. Multi-industry application scenarios and benefit data
Precision casting field
Lost foam casting: XYZ composite vibration eliminates complex cavity air gaps, and the casting yield rate is increased from 85% to 97%;
Resin sand molding: Three-axis timing vibration (frequency 25Hz) makes the sand mold strength fluctuation ≤0.2MPa, and the mold life is extended by 30%.
