Simulation and experimental study of the thermal characteristics of a high-speed motorized spindle

Based on the finite element simulation software ANSYS Workbench, this study reports the thermal characteristics of a high-speed motorized spindle. The temperature field distribution and axial thermal deformation of the motorized spindle are then detected on an experimental platform. A comparison between the experimental and simulation results revealed the temperature rise of the motorized spindle during the working process. Under steady-state conditions of the working motorized spindle, the temperatures of the front bearing, rear bearing and stator were determined as 20°C, approximately 30°C and 25°C, respectively. The axial thermal elongation of the motorized spindle is approximately 10 μm

In this study novel transversal pneumatic artificial muscles (TPAM), made from composite – poly(dimethylsiloxane) (PDMS) matrix membrane and poly(ethylene terephthalate) (PET) satin reinforcement, are presented. Miniature TPAM consists of a flexible internal braid (IB) reinforcing the membrane and the external braid (EB). EB, with fibers arranged transversely to the IB, is placed laterally. Differently prepared TPAMs were tested for their effectiveness as actuators for robot drive and the PDMS/PET composite suitability was evaluated for applications in human gastrointestinal tract (chemical resistance, thermal characteristic). FT-IR spectra of the composite were compared for study PDMS impregnation process of PET satin and effect of immersion in selected solution. The composite shows outstanding biocompatibility and the muscles have competitive static load characteristics in comparison with other pneumatic artificial muscles (PAM). These results lead to believe, that in the near future painless examination of the gastrointestinal tract using a secure robot will be possible.
