VEM-7D dual antenna test host
Overview
VEM-7D dual-antenna test host is a multi-functional vehicle performance test equipment with dual-antenna system and capable of measuring heading angle. It integrates data collection, processing and analysis, and touch display. It has high speed test accuracy, simple operation, and data processing. Convenient and fast, compact structure, easy to carry and other advantages. The following tests can be completed in accordance with the requirements of the national standard:
(1) Power performance, economy, braking performance, odometer calibration, steep climbing, traction performance test, etc.;
(2) 7 tests of handling stability specified in GB/T6323-2014;
(3) The steady state circle test, steady-state cornering test and serpentine test specified by JTT1178.1-2018;
(4) JTT1178.2-2018 specified steady-state circle, steady-state cornering, serpentine, maximum swing and rearward amplification factor test;
(5) Ride comfort test (need to connect vibration measurement module);
(6) Damping ratio and natural frequency test (need to connect vibration measurement module);
(7) ABS test (need to connect frequency module and analog module).
