The relationship between stress and strain is one of the most fundamental concepts from the study of mechanics of materials. When load is applied to the structural members, the strain is recorded with specialized data acquisition software that calculates the load in the members. This vital information allows engineers to verify actual load conditions which can be used to verify design calculations.
Electronic Load Monitoring
With today’s emphasis on product liability and energy efficiency, designs must not only be lighter and stronger, but also more thoroughly tested than ever before. This places a new importance on the subject of on-site stress analysis and load monitoring techniques.
Through the use of modern technology, Bolttech engineers have developed a system to monitor the load distribution of an entire boiler support structure during the construction phase through initial startup. The main theme of this application is aimed at strain measurements using high-precision bonded resistance strain gauges.
The relationship between stress and strain is one of the most fundamental concepts from the study of mechanics of materials. When load is applied to the structural members, the strain is recorded with specialized data acquisition software that calculates the load in the members. Within seconds, the power station engineers are provided with a printout of the load distribution results.
The primary importance of this information is two-fold:
1. Design Validation
The data allows engineers to verify that the loads are within the allowable limits for the particular design, thus avoiding possible overload.
2. Uniform Load Distribution
Bolttech analyzes the results in close liaison with project engineers to develop the appropriate load transfer procedure in order to equally distribute the loads with specially designed hydraulic boiler tools.
