Modular Saddle Mount for Heavy Equipment Cab Vibration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for reducing vibration in heavy equipment cabs do not effectively utilize a detachable saddle mount retained in a modified frame cross member, which is essential for reducing the natural frequency of the base frame and mitigating resonance.
Innovation Solution
A modular saddle mount system that includes a modified frame cross member with opposed mounting blocks and cutout filler inserts, allowing for the attachment of vibration isolators and adjustable height, along with secondary retention devices to secure the cab during rollover events.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mass is added to the frame cross member, then the natural frequency of the base frame is reduced to mitigate resonance, but the overall height and weight of the heavy equipment increase
Solution Approach 1:
The frame cross member is divided into a base structure and a separate saddle mount component. The saddle mount is detachably attached to the base frame cross member, allowing the mass to be segmented and selectively added only where needed for vibration reduction, rather than increasing the entire frame's weight.
Solution Approach 2:
Mass is added locally to the frame cross member through the saddle mount component rather than uniformly throughout the entire frame structure. This localized mass addition targets specific vibration frequencies while minimizing overall weight increase.
2Adaptability or versatility
If a detachable saddle mount is used to retain vibration isolators, then the system becomes more modular and adaptable, but the device complexity increases
Solution Approach 1:
The saddle mount is designed as a universal component that can be detachably attached to various frame cross member configurations and can retain multiple vibration isolators. This multi-functional design allows the same component to serve different purposes while maintaining a relatively simple structure.
Solution Approach 2:
The saddle mount incorporates detachable attachment mechanisms that allow the system to dynamically change its configuration. The saddle mount can be easily attached and detached from the base frame cross member, enabling flexible assembly and disassembly without complex permanent fastening systems.
3Strength
If cutout filler inserts are added to restore rigidity, then the frame cross member rigidity is maintained, but the manufacturing complexity increases
Solution Approach 1:
The cutout filler inserts are pre-fabricated as separate components with the exact geometry needed to restore rigidity to the frame cross member. These inserts are designed to be pre-installed or easily attached to the base frame cross member before the saddle mount is installed, simplifying the overall assembly process.
Solution Approach 2:
The cutout filler inserts act as intermediary components that bridge the gap between the base frame cross member and the saddle mount. These inserts restore the structural rigidity that would otherwise be compromised by cutouts, while maintaining a relatively simple manufacturing process by using separate, pre-fabricated components.

AI summary
A modular saddle mount and modified frame cross member for reducing vibration in heavy equipment cabs preferably includes a heavy equipment modified frame cross member, two modular saddle mounts and at least two vibration isolators. The modified frame cross member includes a frame cross member, two sets of opposed mounting blocks and two cutout filler plates. The two cutout filler plates are secured in first and second cutouts. Each opposed mounting block is secured to an outside of the frame cross member. The modular saddle mount preferably includes a saddle base member and a pair of fastening inserts. A fastening cutout is formed in each end of the saddle base member. The pair of fastening inserts are retained on an inside surface of the saddle base member at opposing ends thereof. At least one isolator opening is formed through the base saddle member to receive a vibration isolator.
