Overview
This page attempts to determine the max carrying capacity before vehicle tipping. Formulas should be provided with variables instead of actual values so that different values can be input to optimize the design.
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
