Optimization design and analysis of mobile pump truck frame using response surface methodology.

Area of Science:

• Mechanical Engineering
• Automotive Engineering
• Structural Optimization

Background:

• Mobile pump trucks require lightweight designs to improve fuel efficiency and maneuverability.
• Existing truck frames may not meet modern lightweighting demands.
• Optimizing the longitudinal beam structure is crucial for overall frame weight reduction.

Purpose of the Study:

• To perform lightweight design on the longitudinal beam structure of a mobile pump truck frame.
• To reduce the overall weight of the mobile pump truck frame.
• To ensure the structural integrity and performance of the optimized frame.

Main Methods:

• Response surface methodology (RSM) was employed for the lightweight design optimization.
• Finite element analysis (FEA) was used to create a model for comparing original and optimized designs.
• Structural performance was evaluated under various motion conditions.

Main Results:

• The optimized longitudinal beam section dimensions were reduced: height by 10mm, width by 11mm, and thickness by 0.8mm.
• The total frame weight was reduced by 35.8kg.
• Optimized design showed minimal changes in displacement and stress under simulated operational loads.

Conclusions:

• The implemented lightweight design successfully reduced the mobile pump truck frame's weight.
• The optimized frame meets the design requirements for lightweighting without compromising structural performance.
• The methodology provides a viable approach for optimizing similar automotive structures.
