Converter Torque Support Dynamics for Vibration Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Converters experience severe vibrations during operation due to the moving steel bath, leading to stress on the casting platform and system parts as rigid brace struts transmit forces, causing damage.
Innovation Solution
The method involves disconnecting the brace strut from the drive and base during operation, allowing the converter to vibrate freely, and optionally using a shock absorber to dampen vibrations, thereby limiting amplitude and reducing stress on the base and strut.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a rigid brace strut is used to support the converter drive, then the structural stability and torque resistance are improved, but the stress on the base and system parts increases due to force transmission
Solution Approach 1:
The brace strut is designed to be dynamically adjustable, transitioning from a rigid connected state during tilting operations to a disconnected state during converter operation. This allows the system to adapt its structural properties based on operational requirements, maintaining stability when needed while reducing stress transmission during violent operations.
Solution Approach 2:
The connection state of the brace strut is changed as a controllable parameter. During tilting, the strut is connected to provide structural support; during converter operation, the connection is disconnected to prevent force transmission to the base. This parameter change resolves the contradiction between needing stability and avoiding stress transmission.
2Stability of the object's composition
If the converter is rigidly fixed to the base, then the positional stability is improved, but the ability to absorb operational vibrations and forces is reduced
Solution Approach 1:
The fixation state of the converter to the base is made dynamic rather than static. The brace strut connects during tilting operations to provide positional stability, then disconnects during converter operation to allow the converter to absorb vibrations independently, thus resolving the contradiction between stability and vibration absorption.
3Strength
If the brace strut remains connected during converter operation, then the structural support is maintained, but the force transmission to the base causes damage to system parts
Solution Approach 1:
The structural support function of the brace strut is activated only when needed (during tilting) and deactivated during converter operation. This dynamic activation maintains structural support when required while preventing force transmission that would cause damage to the base and other system parts during violent operations.
Solution Approach 2:
The force transmission path through the brace strut is extracted or removed during converter operation. By disconnecting the strut from either the base or the drive (or both), the harmful force transmission is eliminated while the structural support function is maintained when the converter is in its operational state.
Applied Scientific Principles
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 approach prevents force transmission to the base, allowing the converter to convert operational forces into movement energy, reducing stress and potential damage by allowing free rotational movement and damping vibrations.
Implementation Method 1
a shock absorber to dampen vibrations, thereby limiting amplitude and reducing stress on the base and strut
Implementation Method 2
The shock absorber that is coupled in is designed in such a manner that it limits the maximal amplitudes of the converter during operation
