Engine Mounts

[smithbeuvic]

Context

Our engine is currently mounted at 4 points ( 2 points on 2 Bolts ). One side of the mounting system is unfinished. It must be redesigned and replaced or verified to be structurally sound through calculation or FEA.

The part is saved in grabcad -> 2016 grabcad -> subassemblies and components -> components-> Powertrain->Engine->Engine Mounts-> Rear clamp mount.

This is the minimum that must be done (Critical Path). Time and resources allowing we will look into implementing a tubular connection to the frame and include vibration dampening in our engine mount.

Outcomes

• Rear engine mount is designed
• Mount is verified through calculation or FEA
• Mount is fabricated and installed OR
• Verify that the current mount is structurally sound

Constraints

• Spacial contraints in the engine bay
• Manufacturability: Should be made in UVic Mech Machine Shop
• The mount must properly locate the engine and withstand its load

Related Issues

Testing should not happen without replacing these mounts

Steps to reproduce behavior

• Review previous design
• Calculate whether or not the current mount is structurally sound
• Learn how the current mount fits into the frame with the engine
• Design a system that will efficiently support and locate the engine.
• Design review: Mechanical and DFM
• Get Ben to fabricate
• Install and test

It should be mentioned that the engine mount has been modified since it was designed so the model may no longer be representative of the actual part (important for FEA purposes). The most significant change effecting the structure of the part was the opening up of the clamping hole to accommodate larger diameter frame tubing.
