Analysis of vehicle ride comfort mainly refers to the vibration and shock environment impact on occupant comfort within certain limits, which will not make people feel comfortable, fatigue and even damage to health performance. Therefore, ride comfort is evaluated mainly based on subjective feelings of the crew, but also for the truck to maintain the performance of the goods in good condition; it is the main performance of modern high-speed car vehicle. The paper proposed a simulation modeling of the vehicle in ADAMS based on the multi-body dynamics theory; we made analysis of vehicle ride comfort on a random road. The result presents the process of building vehicle model and analysis of ride comfort and provides a basis for optimization of vehicle parameters. With this optimized design, the vibration of the vehicle has very significant performance improvements.
