Problems solved by technology

At present, most scholars at home and abroad use the magnitude of the starting flow velocity to judge the stability of the car in the storm water flow. There is a lack of research on the force of the water flow on the car itself in the water flow, and there is no corresponding measuring device.

Abstract

The invention discloses a device for measuring a force applied to a car in water flow. The device mainly comprises a pull force sensor, a first standing pulley, a first rope, a second rope, a second standing pulley, a weight-adding object, a telescopic device and a?position adjusting device, wherein one end of the pull force sensor is fixedly connected with the position adjusting device; one end of the telescopic device is fixedly connected with the other end of the pull force sensor; the first rope passes across the first standing pulley; one end of the first rope is fixedly connected with the other end of the telescopic device; the other end of the first rope is fixedly connected with the head (or the rear) of the car; the second rope passes across the second standing pulley; one end of the second rope is fixedly connected with the rear (or the head) of the car; and the other end of the second rope is loaded with the weight-adding object. The device disclosed by the invention can be used for measuring the circle resistance of a static car in the water flow and the maximal static friction between the car and the ground.

Description

technical field [0001] The invention relates to a measuring device for the force of an automobile in water flow. Background technique [0002] With global climate change and accelerated urbanization, urban floods caused by sudden extreme rainstorms occur frequently. With the development of the economy and the continuous improvement of people's living standards, the number of car ownership continues to increase. Cars on the road or in motion can easily lose stability in sudden torrential rain. [0003] When the front or rear of the car is facing the water flow, it will be affected by gravity, ground support force, water buoyancy, friction between the car and the ground, and water flow resistance. When the buoyancy of the water flow and the resistance of the flow around the car are too large, the car will lose stability and be washed away by the water flow. At present, most scholars at home and abroad use the magnitude of the starting flow velocity to judge the stability of...
