Embodiment Construction

[0023] The specific implementation manners of the present invention will now be described in conjunction with the accompanying drawings.

[0024] combine figure 1 and figure 2 , the tank body pressure distribution test method of the tank car includes the following steps:

[0025] Step 1: A sampling area is set in the tank, a pressure sensing device for collecting pressure data is fixed in the sampling area, and a data acquisition device connected to the signal of the pressure sensing device is set to collect pressure data.

[0026] Use the tank body 1 that has been assembled on the cleaning vehicle to truly simulate the impact of water or other liquid materials stored in the tank body 1 on the head 11 of the tank body 1, such as figure 1 As shown, the sampling area is set on the inner surface of the head 11 on both sides of the tank body 1, such as figure 2 As shown, the sampling areas are arranged sequentially along the height direction of the sealing head 11 when it is ...

Abstract

The invention relates to the technical field of special vehicles and particularly provides a tank pressure distribution test method and a tank internal pressure test device for a tank truck. The testmethod comprises the following steps: (1) setting a sampling area in a tank body, fixing pressure sensing devices for acquiring pressure data in the sampling area, and setting a data acquisition device in signal connection with the pressure sensing devices to acquire the pressure data; and (2) injecting liquid into the tank body to enable each pressure sensing device to be immersed into the liquid, starting the tank truck to drive the tank body to move, and obtaining and processing test data. The pressure distribution at an end socket is obtained in a real test environment, the accuracy of test data can be improved, technicians are helped to master the pressure intensity distribution in the tank body when the vehicle runs, effective data support is provided for the structural design of thetank body in the future, and great help is provided for improving the safety of the whole vehicle.

Description

technical field [0001] The invention relates to the technical field of special vehicles, in particular to a tank body pressure distribution test method of a tank car and a tank internal pressure test device. Background technique [0002] Sprinklers, sweepers and oil tankers in special vehicles are equipped with tanks for storing water, oil or other liquid materials. The tanks include a cylindrical structure as the main body and an opening to the cylindrical structure. The sealing head, the head cooperates with the cylinder to form a complete storage space. [0003] Taking the sweeper as an example, when the sweeper is working, when the tank is fully loaded, the weight of the water stored in the tank accounts for about 40% of the weight of the whole vehicle. During the process of washing the sweeper, the water in the tank The water will collide with the inner wall of the tank under the action of inertia, so that the tank and even the vehicle will vibrate. This situation is m...
