Impact Testing Device Platform Displacement Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional impact testing devices face challenges in achieving precise control and accurate results due to the absorption of impact force by the platform and the generation of reacting forces, which affect the testing results and make it difficult to establish a shock response spectrum (SRS) and determine the reliability and service life of the object under testing.
Innovation Solution
The impact testing device features a first platform for the object, a second platform under the first platform, a plurality of first suspension devices to minimize the displacement of the first platform, and a plurality of second suspension devices to absorb reacting forces, allowing for accurate impact testing data and reduced interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If at least one impact assembly is used to impact the object undergoing testing from bottom to top, then impact testing data can be obtained, but a part of the impact force is absorbed by the platform and consumed by actions unrelated to the impact test
Solution Approach 1:
The platform is segmented into a first platform (supporting the object) and a second platform (supporting the impact assembly), allowing the impact force to be applied directly to the first platform without being absorbed by a separate second platform structure
Solution Approach 2:
The first suspension device acts as an intermediary between the impact assembly and the first platform, transmitting the impact force while isolating the platform from unwanted reactions, ensuring the impact force is not absorbed by the platform structure itself
2Measurement precision
If at least one impact assembly is used to generate impact force, then the object undergoing testing can be impacted, but a reacting force is generated to the impact assembly that will indirectly cause impact to the platform and the object undergoing testing
Solution Approach 1:
The first suspension device serves as a mediator that isolates the reacting force from the first platform and the object undergoing testing, allowing the impact assembly to generate impact force without transmitting harmful reacting forces to the tested object
Solution Approach 2:
The system is segmented into distinct components (first platform, second platform, impact assembly, suspension devices) with clear functional separation, allowing the reacting force to be contained within the second platform and suspension system without affecting the first platform and tested object
3Productivity
If a single impact assembly comprises a plurality of impact hammers, then impact testing can be performed, but the reacting force from one hammer affects the impact force from subsequent hammers causing measurement errors
Solution Approach 1:
The first suspension device acts as a mediator that isolates each impact hammer from the platform, allowing multiple hammers to operate in sequence without their reacting forces interfering with each other or the platform, thus maintaining measurement precision while enabling efficient multi-hammer testing
4Productivity
If the impact hammers impact the platform in sequence, then impact testing can be completed, but insufficient time between impacts allows the platform to not restore its initial stationary position
Solution Approach 1:
The first suspension device serves as a mediator that allows rapid sequential impacts while maintaining platform stability, as the suspension system absorbs and isolates the reacting forces between impacts, eliminating the need for long restoration times between sequential hammer impacts

AI summary
An impacting testing device is provided. The impacting testing device comprises a first platform, a second platform, a plurality of first suspension devices, at least one impact assembly and a plurality of second suspension devices. The at least one impact assembly is disposed on the second platform and faces the first platform for providing at least one impact force to the first platform, and thus, the impact testing is executed on an object disposed on the first platform.
