Lateral stability test system

In order to further improve the lateral stability and operational safety of road vehicles, heavy commercial vehicle trains and articulated passenger cars, 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.

Pilot projects

●7 tests of handling stability specified in GB/T6323-2014

● JTT1178.1-2018 specified steady state circle test, steady state rotation test and serpentine test

The steady-state circle, steady-state rotation, serpentine, maximum swing and rear magnification factor test specified by JTT1178.2-2018

Measurement parameters

●vehicle speed

●Roll angle
