Angled Shock Mounts for Vibratory Plate Compaction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vibratory plates for soil compaction lack optimization in the operation of shock mounts, which affects the efficiency of vibratory forces transmission and stability during uni-directional movement.
Innovation Solution
The vibratory plate features angled shock mounts positioned between the plate and frame, with front mounts operating primarily in shear and rear mounts in compression, allowing for adjustable angles to optimize compaction efficiency and minimize vibration transmission to the frame and operator.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional shock mounts are used with fixed orientations, then the construction is simple, but the performance cannot be optimized for varying operating conditions
Solution Approach 1:
The patent applies the dynamics principle by making the shock mount orientations adjustable rather than fixed. The front shock mounts can be positioned at angles between 0-45 degrees and rear shock mounts at angles between 0-90 degrees, allowing the system to adapt to different operating conditions and soil types while maintaining a relatively simple overall construction.
2Productivity
If shock mounts are positioned to maximize vibratory force transmission, then compaction efficiency is improved, but vibration transmission to the frame and operator increases
Solution Approach 1:
The patent applies the local quality principle by differentiating the positioning and orientation of front versus rear shock mounts. Front shock mounts are angled at 0-45 degrees to optimize force transmission for compaction, while rear shock mounts are angled at 0-90 degrees to reduce vibration transmission to the frame and operator, allowing each location to have optimized properties for its specific function.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration enhances compaction efficiency and uni-directional movement by controlling vibration amplitude and reducing stress on shock mounts, while allowing for fine-tuning to accommodate varying loads and movements.
Implementation Method 1
The frame carries an engine and the plate carries a rotary vibratory exciter connected to the engine by a drive belt. The driven exciter imparts vibratory forces to the plate and the underlying surface material being compacted.
Implementation Method 2
The plate is attached to an overlying frame and separated therefrom by elastomer shock mounts, typically two shock mounts near the front edge of the plate and two mounts near the rear edge of the plate.
Implementation Method 3
The front shock mounts are positioned to operate primarily in shear and the rear shock mounts are positioned to operate primarily in compression.
Implementation Method 4
The front shock mounts are positioned to operate primarily in shear and the rear shock mounts are positioned to operate primarily in compression.

AI summary
A vibratory compaction plate utilizes pairs of front and rear shock absorbing mounts, each pair of which is set at a different angle with respect to the horizontal plate to optimize the respective shear and compression capabilities and optimize performance. A front mounted vibratory exciter and a rear mounted engine provide different performance capabilities that are optimized by the mounting angles. A flat sheet metal plate and sheet metal frame permit the angles at which the shock mounts are oriented to be adjusted along laterally extending end lines to fine tune performance.
