Wedge-Shaped Rotating Body for Multi-Field Coupling

The patent merges electromagnetic loading, thermal loading, and mechanical loading systems into a single integrated device. The electromagnetic loading system uses pulse power supply to generate electromagnetic forces, the thermal loading system uses heating elements to generate heat, and the mechanical loading system uses wedge-shaped rotating bodies to generate mechanical stress. These three systems are combined to simultaneously apply electro-magneto-thermo-mechanical multi-field coupling extreme conditions to the test object, resolving the contradiction by achieving high adaptability through integration while managing device complexity through systematic design

The patent introduces dynamic elements to transform static loading capabilities into dynamic loading capabilities. The wedge-shaped rotating bodies rotate during testing to generate dynamic mechanical loading, the pulse power supply provides time-varying electromagnetic loading, and the heating elements can dynamically adjust thermal loading. This dynamic capability allows the device to achieve synchronous and dynamic loading in extreme conditions, resolving the contradiction between adaptability and complexity by using controlled dynamic processes

The patent uses parameter changes to control the thermal process. The rotation speed of the wedge-shaped rotating body, the pressing force, and the duration of friction heating are all controllable parameters that can be adjusted to achieve the desired surface temperature increase without causing damage. By precisely controlling these parameters, the system can generate sufficient friction heat for testing while avoiding excessive heat that would damage the test object

The patent employs continuous monitoring and control during the friction heating process. The rotation of the wedge-shaped bodies and the application of pressing force are maintained continuously but controllably, allowing the thermal loading to proceed at a controlled rate. This continuous but regulated action ensures that temperature increases remain within safe limits while still achieving the necessary thermal conditions for testing

The patent uses periodic pulse current instead of continuous current to generate electromagnetic forces and Joule heat. The pulse power supply delivers current in controlled pulses rather than continuously, which reduces overall energy consumption while still achieving the necessary electromagnetic and thermal effects during the pulse duration. This periodic action maintains the adaptability to generate electro-magneto-thermo-mechanical coupling conditions while significantly reducing energy consumption compared to continuous operation

The patent employs short-duration high-intensity pulses to rapidly generate the required electromagnetic forces and thermal effects. By concentrating the energy delivery into brief pulse intervals rather than sustained continuous operation, the system achieves the necessary coupling conditions in short bursts, reducing total energy consumption while maintaining the capability to generate extreme multi-field conditions when needed
