Heavy-duty truck emergency brake cargo safety system based on non-Newtonian fluid

Abstract

The invention discloses a heavy truck emergency braking cargo safety system based on non-Newtonian fluid, and relates to the technical field of automobiles. The system comprises a truck carriage, a carriage inner wall, a force guide wall, magneto-rheological dampers, a non-Newtonian fluid emergency braking system, a central controller, a converter, a single chip microcomputer, a data module, a relay, an acceleration sensor, a weight sensor, a distance sensor, a pressure sensor and an energy-saving circuit, wherein the truck carriage comprises an inner wall, the inner wall is provided with theforce guide wall, the pressure sensor is arranged on the force guide wall, and a plurality of magneto-rheological dampers are arranged in the front wall, the left wall and the right wall of the truckcarriage. The heavy truck emergency braking cargo safety system based on non-Newtonian fluid has the beneficial effects that based on the combination of non-Newtonian fluid and the braking system andthe carriage protection of a heavy truck, the braking can be better ensured, meanwhile, the cargo safety is ensured, the speed change rate during emergency braking is effectively adjusted, the situation that the safety of a driver is influenced by the forward movement of cargo during the emergency braking is prevented, and the heavy truck emergency braking cargo safety system is more stable and safe.

Description

Technical field [0001] The invention relates to the technical field of automobiles, and in particular to a heavy-duty truck emergency braking cargo safety system based on non-Newtonian fluids. Background technique [0002] In recent years, non-Newtonian fluid materials have gradually expanded their application fields due to their special rheological properties. The main development trend of non-Newtonian fluid-based materials is that the materials themselves are more intelligent and rheological properties are more controllable. Non-Newtonian fluids refer to fluids whose shear stress and shear strain rate cannot always be linear. Blood, toothpaste, mud, milk, paint and other substances are typical non-Newtonian fluids. The rheological properties and rheological laws of non-Newtonian fluids are more complicated. Different types of non-Newtonian fluids will exhibit different rheological properties under the change of shear strain rate. For example, Bingham plastic bodies have yield...

Problems solved by technology

[0004] At present, in the process of transporting goods by trucks, if the cargo in the cargo compartment is not fully loaded, when the truck is driving on a bumpy road or turning, the goods loaded in the cargo compartment will shift, and the goods will be in the Easily damaged during moving

Even, when the truck is running at high speed on the highway, especially on the expressway, if the cargo compartment is loaded with heavy goods and encounters sudden braking, due to the heavy weight of the goods, the inertia of the goods during the sudden braking will be caused. The bigger it is, the easier it is for the goods to move forward, which will easily cause the goods to damage the front of the car and cause safety accidents for drivers
