Abstract:

In this paper, the National Natural Science Neodymium Magnets Foundation (50705044) 'NC polishing of the mold surface compliance control research "and

Ningbo Key Laboratory Fund (2007A22005) "based on magneto-rheological fluid (MRF) compliant device and its new research in the mold surface

Throw in the application of "soft polishing non-spherical target specific, in-depth study of magneto-rheological fluid device characteristics and in the process of polishing to do

For the moment the application server components.

In this paper, different work MRF model is proposed to control the maximum transmission ratio and

Output (torque) as the evaluation of the magneto-rheological fluid device mode options, and through experimental verification of this criterion is reasonable.



Damping plate for the magnetic field in http://www.everbeenmagnet.com/en/products/110-sintered-neodymium-magnets the non-uniform distribution due to different changes in the output torque, this same control current, the total flux constant and

The average gap for the same constraints and structural parameters to produce the maximum damping torque as an indicator of the shape of the damping of three different gap

To optimize the design. Improved magneto-rheological fluid device output performance.

This paper studies the characteristics of non-spherical rotating body, and magnetic flow

Fluid processing device applications for polishing the torque servo, machining polishing proposed force control room and digital control space accordingly

Share decoupling theory, will work with prototype and CNC machine tools, to achieve a force / position control of the separation of synchronization, an effective solution to the compliance control over

The impact of process variables are many and affect each other hard-line control problems.

This variable will be used in magneto-rheological fluid damping force

Torque servo tool, take advantage of this unique smart materials controllable reversible viscosity, vary widely and fast response characteristics, will be open

Provision of magneto-rheological fluid components for smart new areas of implementation;
