Test method for dynamic lateral stability of multi-functional all-terrain vehicles

1 Scope

GB/T 47046-2026 is the Chinese national standard covering how a utility ATV is tested against rollover - a vehicle with a high centre of gravity, a short wheelbase and no cab, whose rollovers are the commonest cause of death on farms and sites where they are used. First edition. It was issued on 28 January 2026 and has been in force since 1 August 2026, as a first edition. The document is under the responsibility of the Standardization Administration of China. This page is published from the official record of the 2026 edition; the clause text of a standard this recent is not yet in circulation, and the figures, limits and tables it contains are those of the document itself, delivered in full with the English translation.

This document describes the test instruments, equipment, apparatus, test conditions, and test methods for dynamic lateral stability testing of multi-functional all-terrain vehicles. Experimental records. This document applies to multi-functional all-terrain vehicles (hereinafter referred to as "vehicles").

3.1 The inherent anti-roll capability of a vehicle when it is subjected to lateral forces during cornering.

3.2 The inherent anti-roll capability of a vehicle when it is subjected to lateral forces while turning left.

3.3 The inherent anti-roll capability of a vehicle when it is subjected to lateral forces while turning right.

3.4 J-turn test A test to evaluate the vehicle's resistance to rollover when it abruptly transitions from straight-line driving to a J-shaped curve.

3.5 rolangle The maximum angle between the vehicle body and the ground when the vehicle is turning.

3.6 Lateral acceleration The acceleration generated by the lateral thrust due to tire friction when a vehicle turns is the acceleration vector of the vehicle's center of mass (or sprung center of mass) along the y-axis.
