Foreword

This standard was drafted according to GB/T 1.1-2009 given rules. This standard uses the translation method, identical with ISO 9815.2010 "Road vehicles - passenger train lateral stability test." Correspondence between the consistency of the standards of international documents and normative references of the following documents. --- GB/T 3730.1-2001 car and trailer types of terms and definitions (ISO 3833.1999, MOD) --- GB/T 3730.2-1996 road vehicle mass Vocabulary and codes (ISO 1176.1990, IDT) --- GB/T 5910-1998 cars weight distribution (ISO 2416.1992, IDT) This standard by the National Automotive Standardization Technical Committee (SAC/TC114) centralized.

1 Scope

This standard specifies the lateral stability test methods for passenger trains. This standard applies to passenger cars as defined in ISO 3833, light truck and the trailer train composition. Lateral stability test can determine the towing vehicle - trailer yaw oscillation damping characteristics determined by a steering pulse train caused. First, the train stable moving forward, after a single pulse steering lateral oscillation manufacture of the vehicle, the steering wheel remains fixed period of time, Train swing so gradually eliminated. Tested at several different speeds. If aperiodic oscillation occurs, it should provide stability Given test cycle.

3 Definition of Terms and Symbols

ISO 3833, ISO 8855 and defined the following terms and definitions apply to this document. 3.1 Yaw angle hinge yawarticulationangle Δψ XC XT with respect to the corner. X-axis angle between each part, determined by the polarity of the trailer towing vehicle relative rotation angle. Note. The subscript letters C and T denote the tractor and trailer. For example, the longitudinal axis of the tractor axis system for XC, tractor lateral acceleration aYC; The longitudinal axis of the trailer axis system for XT, lateral acceleration of the trailer aYT. 3.2 Average slope meangradient (ofthetesttrack) Vehicle running track between two vertical height divided by the amount of change in the horizontal distance between two points, two points should be as close to the vehicle, respectively, ...
