Abstract

The cargo lifting device for light dump trucks is a device designed specifically

for light dump trucks. This type of vehicle is popular in the market due to its high

flexibility and wide applicability. Mainly focused on the design, performance

optimization, and safety performance improvement of the lifting device for the cargo

compartment of light dump trucks. Specifically, the research team optimized the

structural design of the cargo lifting mechanism through mechanical analysis and

simulation testing, ensuring its stable and reliable operation under different working

conditions.

This article takes 6 * 4 dump trucks and the lifting mechanism of dump truck

cargo boxes as the research object, and conducts relevant research. The main content

of the research includes:

1. Establish a three-dimensional model based on the structural characteristics

and working principle of the front push lifting mechanism of the dump truck;

2. Based on the structure and position parameters of the lifting device for dump

trucks, establish a 3D model of the lifting mechanism in 3D software, and perform

virtual assembly and interference inspection on it;

3. Using finite element software, conduct finite element analysis on the frame,

and obtain a stress-strain distribution map by loading relevant numerical values;

Based on the analysis results, complete the strength analysis of the frame to achieve

the goal of lightweight design while meeting the conditions of stiffness and strength;

4. On the basis of optimizing the lifting mechanism, considering the impact of

random errors such as manufacturing accuracy and installation errors on the lifting

mechanism, optimizing its robustness design, and obtaining optimization results that

are in line with the actual situation, meeting the reliability requirements of the lifting

mechanism.
