Pruning Machine Concept Structure and Stability Validation According to CSA Standard Elevating Work Platforms
The simulation allowed Lx Sim to propose necessary modifications to R.F. Innovation to comply with the standard and to validate that the final design met the criteria.
Phase 2: Wind Stability Validation
To comply with CSA elevating work platforms standard, the stability against the wind of the pruning machine had to be validated. Specifically, the machine has to remain stable in the most critical position, under nominal loading, facing a 12.5m/s wind. Lx Sim used CFD analysis to measure the wind loads on the entire structure. The resulting pressure was then applied to the mesh in the FEA analysis, which was then used to evaluate the reaction forces on the ground under the stabilizing legs of the machine. The results were used to give conclusions on the stability of the machine facing a 12.5m/s wind.
Evaluation of reaction forces under the stabilizing legs showed that the machine was stable against a 12.5m/s wind and complied with the CSA standard for wind stability.
