Lateral stability test system

Overview

In order to further improve the lateral stability and operational safety of road vehicles, heavy commercial vehicle trains and articulated buses, effectively curb and reduce road transportation safety accidents caused by insufficient safety performance of the vehicles themselves. Our company has specially developed a set of lateral stability test system. The system has powerful data collection and analysis functions, automatic data classification management, easy installation of equipment, humanized software and hardware operation, and supports rapid generation of test reports. This system is a commercial truck Ideal product for safety testing.

Test programmes

7 tests of handling stability specified in
JTT1178.1-2018 specified steady state circle test, steady-state cornering test and serpentine test
The steady-state circle, steady-state cornering, serpentine, maximum swing and rearward amplification factor test specified by JTT1178.2-2018

Measurement parameters
