Design a Yogurt Pouch Distributor

Discipline

Year

2015

Project Description +

Ultima Foods has been recognized as a major player in the food industry for more than 40 years. The company offers a wide variety of dairy products, and more specifically yogurt, sold across Canada.

Ultima Foods wanted to improve the performance of the yogurt pouch distributor installed in its Granby plant. The client had already noticed some problems, such as, among other things, the fact that the system did not detect the absence or presence of several pouches in the distributor, resulting in a loss of efficiency or equipment shutdown. The client also wanted to optimize the distributor cycle times. LDV was therefore mandated to design and produce the drawings of a new system that would solve the problems that had been identified.      

As part of the mandate, LDV carried out, among other things, the following:

  • Produce design sketches;
  • Produce a detailed design of a distributor that is in compliance with the food standards;
  • Calculate the operational clearances of the assembly;
  • Produce the drawings needed to manufacture the parts and install them;
  • Produce drawings in DXF format for the parts that needed to be laser cut (unfolded sheet metal and plate).

Project Description +

The Weir Group is a world-class global engineering group that designs and manufactures highly-engineered products and services for minerals, oil and gas, and power industries.

Weir Canada was mandated to machine plastic strips on the outside of a 14-m diameter rotor installed in a hydroelectric power plant. To do so, Weir called on LDV to provide the tooling design and engineering.      

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

  • Produce the tooling design, model, design calculations and drawings;
  • Perform a finite element analysis to validate the mechanical resistance of the assembly;
  • Perform a modal analysis to predict the tooling frequencies and avoid vibrations during machining.   

To deliver a high quality service and promote close collaboration and communication with the Weir personnel, LDV's engineers travelled daily to the Weir Canada offices in LaSalle.

2015

Project Description +

Bombardier Aerospace designs and manufactures aviation products for the business and commercial aircraft markets.

As part of the project to design a ballast supporting tool for Bombardier Aerospace, they wanted to validate the ballast support structure to ensure that the tool met the design criteria. 

The tool had to support weights (ballast) to keep the nose of the C-Series plane on the ground during final assembly.

Hence, LDV performed the finite element analysis and manual calculations required to validate the structure, recommended changes to specific areas and approved the drawings used to manufacture the tool.

Resistance Analysis of a Visor

Discipline

Digital Simulation

Year

2014

Project Description +

As part of the project, the client needed to validate the compliance of a visor with standard CSA Z262.2. Given that digital analysis software had to be used, the client called on LDV Consultants to conduct an analysis in accordance with the criteria set out in standard CSA Z262.2 and propose the changes required to improve the design and achieve compliance of the visor.        

The analysis was carried out using ANSYS and the LS Dyna module. The analysis included the following:  

  • Perform an explicit non-linear analysis (impact);
  • Evaluate two impact speeds;
  • Identify the restrictions on deformation and breaking.

Thanks to the expertise and cooperation of LDV's analysts, the client got a design that was in compliance with the applicable standard, and was thus able to go on to the next phase of its product development process.

Established for more than 20 years, Coprodev Plus is the reference in industrial cheese cutting equipment for high throughput production lines. The company specializes in reducing 640 lb or 40 lb blocks of cheese into portions.

Coprodev Plus called on LDV Consultants to provide their technical support services for the design and layout of cheese cutting equipment and other related equipment.  

LDV's designers worked closely with Coprodev Plus personnel from LDV's offices in Chambly. They also travelled, as required, to the Coprodev Plus offices in Boucherville, to ensure effective collaboration.

Thermomechanical Analysis of the Impact of the Repairs on a Steam Boiler Tubes

Discipline

Mechanical Engineering

Year

2013

Project Description +

Norda Stelo is a consulting group involved in all engineering disciplines. As part of the project, Norda Stelo had to repair the cooling tubes on a steam boiler. To validate the efficiency of the repairs, Norda Stelo mandated LDV to carry out a comparative thermomechanical analysis.

LDV modelled three cooling tube configurations. The first configuration showed the cooling tubes as per the original 1965 design. The second configuration showed the cooling tubes after the repairs made in 2011 whereas the third configuration showed the repairs that Norda Stelo had to make. The thermomechanical analysis was carried out while taking into account the operating temperatures and pressures, the mechanical properties of the materials based on temperature as well as the convection, radiation and conduction heat transfer coefficients.

The LDV analysis made it possible to conclude that the new repairs would significantly reduce the stress on the critical areas of the cooling tubes. Satisfied with the results, Norda Stelo decided to move forward with the repairs.

Project

Design Tooling for Stator and Bulb Nose Assembly

Discipline

Mechanical Engineering

Year

2010

Project Description +

GE Renewable Energy was awarded, in 2008, a contract to design, manufacture and install generating units for the La Sarcelle power plant in James Bay. In addition to designing the units, the project also included the design of special tooling for mounting and positioning key components. Among the components, the stator (170 metric tons) and bulb nose (50 metric tons) for each group had to be lowered into the hydraulic passage upstream of the embedded parts, and then relocated upstream and eventually returned downstream to the place where they were to be positioned and installed on the fixed parts of the unit.

GE Renewable Energy therefore mandated LDV to design tooling for handling the stator and bulb nose for the La Sarcelle facilities. Using SolidWorks, LDV designed and 3D modeled the handling system to be installed in the section upstream of the hydraulic passage. The system included handling rails, support beds for the bulb nose and stator, and a positioning table. In addition, LDV performed the various calculations set forth in the client’s requirements.

Final deliverables included manufacturing and assembly drawings, calculation notes and instructions for equipment assembly.

Project Description +

Alstom Power Canada was awarded, in 2008, a contract to design, manufacture and install generating units for the La Sarcelle power plant in James Bay. In addition to designing the units, the project also included the design of special equipment for handling and moving key components. These components included, among other things, half-distributors, preassembled at the Eastmain power plant, that needed to be moved to the La Sarcelle power plant, located approx. 70 km away.   

Alstom therefore mandated LDV to design the tooling needed to transport the half-distributors to the La Sarcelle facilities. Using SolidWorks, LDV designed and 3D modeled a handling system to move the trailer-installed half-distributors. In addition, LDV performed the various calculations required for compliance with the applicable specifications and codes.

Design of a Mobile Walkway

Discipline

Mechanical Engineering

Year

2009

Project Description +

Alstom Power Canada was awarded, in 2008, a contract to design, manufacture and install generating units for the La Sarcelle power plant in James Bay. Aiming to focus on its core activities, i.e. designing and manufacturing turbine-generators, Alstom wanted to find a business partner to design other equipment.

Alstom Power Canada therefore mandated LDV Consultants to design the mobile walkway needed to ensure maintenance of the La Sarcelle turbine.

Using SolidWorks, LDV designed and created a 3D model of the mobile walkway, which included several design constraints such as the fact that each section of the walkway could not weigh more than 35 kg. LDV also made all the necessary calculations according to the Alstom’s requirements. Final deliverables included manufacturing and assembly drawings as well as design notes.
