The car ride comfort test and analysis system is a PC-based intelligent test platform designed for the analysis and processing of vehicle vibration signals. It is especially suitable for vehicle ride comfort tests (random input and pulse input), and conforms to GB4970-2009 car ride comfort Sexual test standards and data processing standards. It is also suitable for vehicle suspension natural frequency damping ratio test and other ordinary vibration analysis, and supports noise test (optional).
