Force transmission characteristics in a multiple-fulcrum supporting platform with heavy loads

Area of Science:

• Mechanical Engineering
• Statics and Dynamics
• Structural Analysis

Background:

• Multiple-fulcrum supporting platforms are crucial in various engineering applications.
• Achieving uniform force distribution is essential for platform stability and longevity.
• Existing methods often struggle with heavy loads and dynamic reconfiguration.

Purpose of the Study:

• To investigate the force transmission characteristics of multiple-fulcrum supporting platforms.
• To propose a novel law for uniform force distribution under heavy loads.
• To develop layout reconfiguration methods for achieving uniform forces across diverse constraint surfaces.

Main Methods:

• Construction of a detailed force transmission model for the supporting platform.
• Analysis of the relationship between force transmission and layout parameters.
• Development and application of layout reconfiguration strategies.
• Validation through ADAMS multi-body dynamics simulation.

Main Results:

• Discovery of a layout law for achieving equal supporting force across all fulcrums.
• Demonstration that uniform force distribution is achieved when the layout central point (LCP) coincides with the force equivalent point (FEP) of external loads.
• Successful application of reconfiguration methods across rectangular, circular, and unconstrained surfaces.

Conclusions:

• The study provides a theoretical framework for uniform force distribution in multiple-fulcrum supporting platforms.
• The proposed layout reconfiguration methods offer practical solutions for engineering challenges.
• The findings guide the design and optimization of supporting platforms for enhanced performance and reliability.
