LifeTrac IV/Research Development/Carrying capacity

Overview

This page provides information for the approximate carrying capacity before vehicle tipping. Additional information is desired to determine structural strength when loaded. Operating load is defined as 50% of the tipping load.

Analysis

Wanted: Formulas for calculating the tipping loads and force distribution

• Assume symmetric weight
• LifeTrac image in MS Word file
• Basically what we need is an understanding between carried load CofG, vehicle CofG, arm pivot location, hydraulic cylinder mounted location and the front wheel which acts as the point to tip around.
• Keep everything in x-y coordinate system for the initial static analysis and then provide the formula as a function of load location as it arcs around the loader arm pivot point at the top of the frame.
• The end goal is to have a formula that can be applied to any design
• Add whatever additional considerations are required to make the analysis more accurate
• Please provide definitions of variables used, easily understood diagram and formulas
• If uploading to wiki is a problem, please email data to Mike Apostol directly
