Solution Overview

Problem

Conventional horizontal slide tables in vibration tables lack a displacement measuring and protecting device, leading to potential failure or damage during maximum displacement horizontal vibration tests due to excessive displacement caused by the trunnion vibration isolation mechanism.

Innovation Solution

A device comprising a displacement detection assembly, a displacement detected assembly, and a vibration controller that measures the absolute vibration displacement of the horizontal slide table in real time and controls the vibration table to stop when the displacement exceeds a preset limit, thereby protecting the horizontal slide table.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a trunnion vibration isolation mechanism is used to reduce vibration transmission, then vibration isolation performance is improved, but the actual displacement of the horizontal slide table becomes greater than the exciter displacement

Engineering Contradiction:

Improvevibration isolation performanceVSAvoidactual displacement of horizontal slide table

Core Design Contradiction:

ReliabilityVSLength of moving object

Solution Approach 1:

The displacement detection assembly is installed beforehand on the horizontal slide table to detect displacement before damage occurs. The system preset a maximum displacement threshold, and when the detected displacement approaches this threshold, the control system stops the vibration table in advance, preventing the slide table from exceeding its safe displacement range.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The displacement detection assembly provides real-time feedback on the horizontal slide table's displacement to the control system. This feedback loop enables the system to monitor displacement continuously and trigger protective shutdown when the preset threshold is approached, resolving the contradiction by making the system responsive to the actual displacement conditions created by the vibration isolation mechanism.

Inventive Principle:

Principle #23Feedback

2Device complexity

If no displacement measuring device is installed on the horizontal slide table, then device complexity is reduced, but the horizontal slide table cannot be protected during maximum displacement tests

Engineering Contradiction:

Improvestructure complexityVSAvoidprotection capability

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The protection system is segmented into independent functional modules: a displacement detection assembly mounted on the horizontal slide table, a control system with preset thresholds, and a vibration table. This modular segmentation allows the protection function to be added without fundamentally redesigning the entire system, balancing complexity and reliability.

Inventive Principle:

Principle #1Segmentation

3Reliability

If real-time displacement measurement and protection control are implemented, then reliability of horizontal slide table is improved, but device complexity increases

Engineering Contradiction:

Improveprotection capabilityVSAvoidstructure complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The displacement detection assembly serves multiple functions: it detects displacement for measurement purposes, provides feedback for control, and enables protective shutdown when thresholds are exceeded. This multi-functionality reduces the need for separate systems for each function, thereby limiting the increase in overall device complexity while achieving comprehensive protection.

Inventive Principle:

Principle #6Universality (Multi-functionality)
