Abstract

The invention discloses a real-time simulation test bench which can be used for fluid-solid two-way coupling property studying on a tank truck and tank truck control strategy development. The test bench is composed of a shrinkage-ratio fluid tank motion platform assembly, a tank truck real-time simulation platform, a human-computer interaction debugging platform, a driver operation device and a driver visual system. The shrinkage-ratio fluid tank motion platform assembly is used for simulating the motion of a fluid tank, and the fluid tank is controlled to move by a six-degrees-of-freedom motion platform controller. The tank truck real-time simulation platform is used for performing dynamic response calculation on the tank truck, performing similarity transformation on the dynamic characteristic between the shrinkage-ratio fluid tank and an actual fluid tank, and performing signal acquisition and motion control on the shrinkage-ratio fluid tank motion platform in real time. The test bench simulates the motion and dynamic property of the tank truck through real-time information interaction between the shrinkage-ratio fluid tank and a truck dynamical model, and fluid-solid two-way coupling and real-time simulation of fluid in the tank truck and the truck are really achieved.

Description

technical field

[0001] The invention relates to a two-way coupling real-time simulation test device of a liquid tank vehicle, which is used for the research of the liquid-car body two-way coupling characteristics of the liquid tank vehicle and the development and verification of the stability control strategy of the liquid tank vehicle. Background technique

[0002] As my country's demand for chemical products expands year by year, the volume of liquid chemical products transported by road continues to rise. According to statistics, in recent years, the annual transportation of liquid chemical products is about 200 million tons, 80% of which are completed by road transportation. Due to the mutual coupling effects of liquid sloshing in the tank and vehicle motion, lateral instability and rollover accidents such as folding and shimmy are prone to occur during obstacle avoidance. The vehicle stability of liquid tank vehicles is more complicated than that of general commercial v...
