Boucherville - Design a Test Bed

Client

TM4

Project

Design a Test Bed for an Electrical Motor

Discipline

Mechanical Engineering

Year

2014

Project Description +

TM4 designs electrical motors suitable for the automotive market. To carry out the tests required to certify the motors, TM4 mandated LDV Consultants to design one of its test beds.  

The TM4 motor needed a test bed that would allow the drive shaft to rotate in both directions. What made this test bed unique was the fact that the power transmission had to go through a belt. To facilitate the required movement with the type of transmission selected, LDV had to design and test a double tensioner system.       

The engine torque was monitored during testing. Selecting the drive shaft tolerances between the pulley and the torquemeter was a critical process as this could affect the test results.

Magog - Optimize the Drive System Parts

Client

Camoplast Solideal inc.

Project

Optimize the Drive System Parts

Discipline

Computer simulation

Year

2014

Project Description +

Camoplast Solideal is a world leader specialized in the design, manufacturing and distribution of off-road tires, wheels, rubber tracks and running gear systems for the material handling, construction, agriculture, motorized sports and defense industries.    

Camoplast Solideal implemented a procedure the purpose of which was to optimize the components of the track drive system on the John Deer tractor in order to reduce the number of components in the track drive system and in turn, lower the costs incurred to manufacture and install the drive system. 

It is within this context that Camoplast Solideal mandated LDV to perform computer simulations of the new designs.  

LDV was responsible for evaluating the internal stresses using various loading scenarios and comparing the results with the existing parts. The results were submitted to Camoplast Solideal in a summary report prepared by LDV.

Year

2012

Project Description +

Bombardier is a recognized world leader in ground and air transportation. Its Bombardier Transportation division offers one of the most comprehensive rail vehicle portfolios in the world.  

RapidKL, a public transportation service company in Kuala Lumpur, Malaysia, mandated Bombardier to perform the engineering and supervise the work needed to be able to couple four cars together.

Bombardier Transportation, Kingston division, mandated LDV Consultants to inspect the cars that needed to be converted, outline the scope of the work to be carried out and validate the required changes through calculations and analysis. In addition, LDV was tasked with the following: draft a detailed procedure, certify welder qualifications, provide technical support to the Bombardier team in Malaysia and supervise the work on site.

Montreal - Renaissance Car Steps

Client

Via Rail

Project

Design New Car Steps for Renaissance Railroad Cars

Discipline

Mechanical Engineering

Year

2012

Project Description +

Via Rail is renowned as a leader in rail passenger transportation. Via owns and operates Renaissance long-distance intercity railroad cars.  

Renaissance cars are equipped with retractable car steps to facilitate access to the cabin. Given that access platforms in some train stations are four (4) inches higher than those found in other stations, the car steps cannot be fully open without coming into contact with these platforms.      

LDV was therefore mandated to design a new retractable car step that could be adapted to the existing car, with minimum changes to the car.
