Solution Overview
Problem
Current mounting assemblies for rotating machines are inefficient in preventing rotational rigid body modes and require lengthy and intricate investigation techniques, often necessitating dismantling of the machine and support frame to adjust structural modifications, which is time-consuming and costly.
Innovation Solution
A mounting assembly with a support frame structure featuring traverse members, attachment mechanisms, and turnbuckle attachments that increase directional stiffness, allowing for on-site tuning without removing the machine or assembly from the foundation, thereby preventing rotational rigid body modes by arresting rolling and pitching motions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional mounting assemblies are used to support rotating machines, then the machine weight is supported, but rotational rigid body modes cannot be effectively prevented
Solution Approach 1:
The support frame structure is divided into multiple longitudinal sections connected by traverse members, creating a modular segmented structure. This segmentation allows independent adjustment of each segment's stiffness characteristics through attachment mechanisms, enabling prevention of rotational rigid body modes while maintaining overall structural simplicity.
Solution Approach 2:
The mounting assembly incorporates adjustable attachment mechanisms with turnbuckles that allow dynamic modification of structural stiffness. The attachment mechanisms can be tuned to provide optimal stiffness in specific directions to prevent rotational modes, transforming a static rigid structure into a dynamically adjustable system.
2Reliability
If structural modifications are made to alter rigid body modes, then rotational motion is prevented, but the machine and support frame must be dismantled and removed from foundation
Solution Approach 1:
The attachment mechanisms are designed with adjustable components including turnbuckles that enable on-site tuning of structural stiffness without requiring dismantling. This dynamic adjustability allows modification of rigid body modes while the machine remains installed on its foundation, eliminating time-consuming dismantling and reassembly operations.
Solution Approach 2:
The structural stiffness parameters of the mounting assembly can be modified by adjusting the attachment mechanisms in place. By changing the tension or configuration of the attachment mechanisms, the stiffness characteristics are altered to prevent rotational modes without physical modification or dismantling of the support frame structure.
3Reliability
If conventional mounting assemblies are used, then machine weight is supported, but directional stiffness is insufficient to arrest rolling and pitching motions
Solution Approach 1:
The attachment mechanisms are strategically positioned and configured to provide enhanced stiffness in specific directions where rolling and pitching motions occur. Rather than uniformly increasing stiffness throughout the entire structure, the attachment mechanisms locally reinforce the support frame in critical areas, effectively arresting rotational motions while maintaining overall structural efficiency.

Implementation Method 1
a turnbuckle connecting each of the two hinge plates to at least one fixing plate fastened to a vertical section of the machine, wherein the attachment mechanism arrests any or a combination of rolling mode of motion and pitching mode of motion of the support frame structure and the machine by increasing the effective stiffness of the support frame structure
Implementation Method 2
Such mounting assemblies are intended to absorb vibrations, but must also be capable of supporting weight of the machines and its dynamic forces during operation
