It's show clearly that the MVSD model react the realistic manner than MOVM and VSDM in braking case.
Figure 12 represents the snapshot of vehicle motion and their behavior according to MVSD, VSD, OV, and MOV models.
The alternates for varying flow on constant speed motors are pocket-loaded reciprocating compressors or variable speed gears (MVSD) on centrifugal compressors.
The hydrodynamic torque converter installed in a Voith MVSD, dampens the effects of these starting torques from 300% of nominal torque at the motor-to-MVSD coupling down to 65% of nominal at the compressor-to-MVSD coupling.
D-R had applied these MVSD packages in other compressor applications, but had not teamed with WGP on a Voith MVSD application.
The motor and MVSD were mounted on a common skid and the equipment was mated to the separate compressor skid at the site.
Due to the MVSD gearing, a large amount of oil is required for its operation.
The multiple vertebral and rib malformations in our patient are consistent with the diagnosis of MVSD. Since our patient represents a sporadic case of MVSD, definitive classification is difficult.
Multiple structural abnormalities of the spinal cord and brain have been described in patients with MVSD including cerebral polygyria, (7) diastematomyelia, (8) Arnold-Chiari malformation with thoracolumbar meningomyelocele, (9) thoracolumbar rachischisis5 and hydrocephalus due to aqueductal stenosis, spina bifida cystica in the thoracolumbar region, and diastematomyelia.
Historically, patients with severe MVSD have had a high infant mortality rate due to early respiratory compromise.
As previously noted, multiple brain and spinal cord anomalies have been described in patients with MVSD. Based on the findings in our patient, we suggest that tethered cord be added to the list of spinal cord abnormalities.
