SENSITIVITY OF THE MINIMUM ALLOWABLE VEHICLE-GUIDEWAY CLEARANCE TO GUIDEWAY IRREGULARITY ROUGHNESS AND WAVELENGTH CHARACTERISTICS CONSIDERING CONTACT FREQUENCY

This paper pertains to the calculation of the minimum clearance which can be achieved for a vehicle with both a primary and secondary suspension. Dynamic stiffness characteristics which provide minimum vehicle-guideway contact frequency for a maximum tolerable RMS acceleration specification on the primary suspension are used to define the minimum achievable clearance as a function of guideway roughness characteristics. As demonstrated, the computed minimum clearance is very dependent on the assumptions regarding the statistical roughness characteristics of the guideway irregularities and on the assumptions regarding the maximum and minimum irregularity wavelengths considered in the calculation. A sensitivity analysis is included.
