TURBINE SHAFT FEA ASSESSMENT

USA

Client : GE Renewable Energy Canada

Location : USA

Year : 2018

As part of a submittal requisite, the owner wanted to have a preliminary study of the turbine shaft structural integrity in order to assess if the component was robust enough to undergo another 40 years of service life in addition to a power increase.

LDV Mandate

  • Perform a FEA analysis of the turbine shaft to better understand its physical behavior under its normal and steady state load conditions.
  • Calculate by finite element analysis (FEA) the Von-Mises equivalent static stresses in the turbine shaft at full load in normal operating condition and compare the results against the criteria commonly used in the hydro business.
  • Calculate by FEA the Von-Mises equivalent static peak stresses in the turbine shaft for different fatigue cycles and compare the results against S-N fatigue curves commonly used in the hydro business to evaluate the cumulative fatigue damage.
  • Calculate by FEA the maximum allowable crack which is not propagated under the maximum load in normal operating condition using the methodology found in the API579-1/ASME FFS-1 Standard.

The preliminary finite element analysis showed that the base material of turbine shaft is robust enough to withstand an additional 40 years of service life and a maximum allowable crack size was identified.

 

Modifications to the Gasti Machine

Boucherville,Quebec

Client : Danone Inc.

Location : Boucherville,Quebec

Year : 2017

Danone is a French agrifood company that has focused its business on four sectors of activities: fresh dairy based products, bottled waters, medical nutrition and early life nutrition. The company is one of the world leaders in these four sectors of activities. Its products are sold worldwide.

During maintenance of the machine that seals the yogurt jars, operators had difficulty closing the machine because of the gas cylinder that made it easier to open the machine. Furthermore, because this machine is performing repetitive movements, the air intake ducts and electric wiring wear out prematurely. The client therefore mandated LDV Consultants to examine both problems.

As part of the mandate, LDV Consultants carried out the following:

  • Take measurements on site and produce a 3D model of the existing machine;
  •  Provide a diagnosis on component wear and tear;
  •  Provide a 3D model, drawings and assistance for the purchase of the supports needed to improve the life cycle of the air intake ducts and wiring;
  • Perform the analytical calculations for the power needed to open the gas cylinder;
  • Propose modifications to optimize the machine closing and opening ratio;
  • Produce the machine drawings, including all wear and tear parts.

LDV Consultants' expertise enabled the client to increase the efficiency of its process while rendering it more secure during maintenance work.

Finite Element Analysis of the Pole and Rim

New Zealand

Client : New Zealand Operator

Location : New Zealand

Year : 2017

Following the inspection of the units of a New Zealand operator's hydroelectric power plant, LDV Consultants was mandated to conduct an analysis on the units of the hydroelectric power plant to draw up a series of recommendations and inspections for future unit shutdown. As part of the project, LDV Consultants was mandated to conduct a finite element analysis on the rotor trunnion pole and rim.

The purpose of this analysis was to determine the actual condition of the rotor's two main components given that the units, that are operational since 1967, have never undergone any major refurbishing.

The purpose of the finite element analysis was to determine the stresses and deformations of the rim and pole under various loading conditions so as to calculate their remaining useful life. Static stress and fatigue damage calculations were therefore performed as per the recommendations in the ASME Boiler and Pressure Vessel Code, Section VIII, Division 2. The analysis was conducted, using ANSYS Workbench r.18.2, on an assembly that included the rim and pole.

FEA of a MIV

North America

Client : Major North American Company

Location : North America

Year : 2017

As part of a vast rehabilitation and certification project for its production units, a major North American compagny mandated LDV Consultants to perform a finite element analysis (FEA) of large main inlet valves (MIV) installed in a power house.

The purpose of the FEA was to determine the best solution, i.e. to replace or rehabilitate the MIV, from an economical point-of-view, but also from a safety perspective as the MIV plays an essential role in the safety and integrity of the turbine parts, generator parts and entire power house.

To achieve this objective, the stress fields and deformations under several load conditions were calculated by FEA. The different load conditions were then combined to evaluate the theoretical residual operating life of the MIV. The stress and cumulative fatigue damages were calculated and verified in accordance with the ASME Boiler & Pressure Vessel Code, Section VIII, Division 2 methodology and criteria. The FEA was performed using Ansys Workbench 17.2.

Thermal-Mechanical Analysis of a Converter

Rouyn-Noranda, Quebec

Client : Norda Stelo

Location : Rouyn-Noranda, Quebec

Year : 2016

Norda Stelo is a consulting firm specialized in all engineering disciplines. As part of this project, Norda Stelo wanted to check the integrity of the converter’s structure because it had sustained permanent deformation while in service.

A first thermal-mechanical analysis was conducted to understand the reason why the external part of the roof was buckling. 3D modelling of the insulation helped to reveal the type of buckling and to make recommendations in order to prevent it from happening.

Thereafter, a second thermal-mechanical analysis was conducted to quantify the impact that the lack of insulation may have during equipment refitting.

Some critical zones were identified and these were the zones where it was impossible to replace the insulation already installed. It was however possible to replace much of the insulation in the equipment while maintaining equipment operation.

LDV Consultants made its recommendations regarding the possibility of maintaining the integrity of the client’s equipment and presented its guidelines as to the refurbishing procedure from a thermal-mechanical point of view.

Next-Gen EPS Harmonic and Thermal Analysis

Grand-Mère, Quebec

Client : Kongsberg Automotive

Location : Grand-Mère, Quebec

Year : 2015

Kongsberg Automotive, together with its clients from the industrial and transportation sectors, specializes since 1988 in the design, development and manufacturing of integrated quality and high value-added solutions for the field of electronics and electro-mechanics.

During the design phase of an electronic controller, Kongsberg Automotive wanted to make sure that the controller would operate properly. LDV was therefore mandated to perform a finite element analysis to determine displacement with various loads. LDV carried out the following:

  • Perform structural analysis with a thermal load to simulate variations in operating temperatures; 
  • Perform harmonic analysis to simulate potential vibrations on the component during operations;
  • Perform modal analysis to validate some of the material properties with the vibration tests carried out by Kongsberg Automotive.

This project allowed us to determine maximum displacement during the electronic assembly operation. It also made it possible to show that the assumptions made by Kongsberg Automotive as they pertained to the materials, did not reflect reality.  LDV was able to provide Kongsberg Automotive with more accurate values for this material.   

Validation of a lifting tool
