Embodiment Construction

[0033] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0034] Such as figure 1 As shown, the present embodiment provides a method for calculating the fatigue life of the sliding plate of the material suction and discharge vehicle, which includes the following steps:

[0035] (1) Establish a 3D overall finite element model of the sliding sheet including the tank body, use 3D CAD software to establish a 3D overall geometric model of the sliding sheet including the tank body, import the geometric model of the sliding sheet into the finite element software, and define the unit type , set the material parameters, define the meshing parameters and carry out meshing, where the joint between the sliding plate and the tank body is finely meshed, and the fine meshing refers to reducing the mesh to the original mesh size 50% to 70%.

[0036] (2) Calculate the fatigue life of the sliding plate under the material suct...

Abstract

The invention discloses a calculation method for fatigue life of a material sliding plate of a material suction and discharge vehicle. The method comprises the steps of performing power analysis on afinite element model to obtain a transient stress of a maximum stress node under the condition of different material densities, tilt angles of the material sliding plate and mileages; then calculatingthe fatigue lives of the material sliding plate under a material suction condition, a material discharge condition and a driving condition, and based on this, performing calculation to obtain the total fatigue life of the material sliding plate; and finally building a quadratic polynomial calculation model of the fatigue life of the material sliding plate under the condition of the different material densities, the different tilt angles of the material sliding plate and the different mileages. Through the calculation method for the fatigue life of the material sliding plate of the material suction and discharge vehicle, the material sliding plate of the material suction and discharge vehicle can be subjected to fatigue life calculation, so that the analysis time is shortened, the calculation efficiency and precision are high, and an engineering basis is provided for material selection of the material sliding plate.

Description

technical field [0001] The invention belongs to the simulation field of material suction and discharge vehicles, and in particular relates to a calculation method for fatigue life of a sliding plate of a material suction and discharge vehicle. Background technique [0002] The material suction and discharge vehicle is a professional logistics vehicle engaged in the transportation of bulk materials. It is used for the whole closed transportation of powdery and granular dry bulk materials such as mineral powder, fly ash, and grain. It can reduce the loss of bulk materials, reduce loading and unloading costs, and save packaging materials. , Improving the working conditions of workers, improving work efficiency, and protecting the environment are of great significance. The working principle of the material suction and discharge vehicle is to use the vacuum pump to generate negative pressure to suck the material into the tank, then drive the suction and discharge vehicle to the d...
