43014 Applied Mechanics and Design B

Spring 2024

Subject description

Failure of engineered systems leads to increase in costs, downtime in manufacturing and potentially even loss of life. This subject explores some of the many failure modes associated with machine components. It enables students to design and analysis frames and machines for stiffness, strength, fatigue life, fast fracture and other failure modes. Specifically, students perform; external and internal load analysis by applying principles of stress, strain, free body diagrams and equilibrium; selection and sizing of materials and member of appropriate sizes considering the impact of failure modes, including Fatigue, fracture, buckling; referring to relevant standards and codes to assess design for safety; use these theories in conjunction with computational tools to undertake design optimisation and simulation for virtual testing; and undertake experimentation to verify and validate simulation and theoretical results.

Further           Detailed project description will be provided on UTSOnline. information:  For example:

CubeSats Widgets are a variety of small, short lifespan devices that are often used for educational   and short duration scientific purposes. The Chassis of the Widget CubeSat itself is critical to the life, protection and performance of the device. It must protect the package from loads and ensure

successful delivery to orbit.

The objective of this project is to design the structural frame. of a CubeSat Widget. the device itself is exposed to a number of different events during its operation. the launch and orbital process,

including (1) device assembly and transport, (2) booster launch, (3) high g manoeuvring, and (4) thermal cyclic fatigue.

Student will need to develop a series of load cases based off their student number and apply these to a specified package that will be delivered to orbit. FEA and design optimisation tool should be applied to minimise weight without degradation of structural performance.

A material sample will be provided to the students and they should use mechanical testing devices to determine material properties.

Students will be provided with a material sample and all the necessary information to complete their project:

Students should attend a lab session and undertake materials testing to determine main properties of their sample. this will form. the basis of their design task.

A unique load case design will be developed as follows based on your student number to cover the main load case scenarios.

12345678

12 – maximum g during manoeuvring

3 – dd = vertex impact from drop, even = edge impact from drop

4 – maximum impact g (3 x multiplication factor)

56 – maximum g exposure at launch

78 – cyclic fatigue rate in RPM

A corner or edge impact is possible during handling in the lab. The chassis should be sufficiently strong to withstand this impact.

Thermal expansion occurs with when side panels of the CubeSat are exposed to the sun, where they are cyclically heated and cooled through temperature extremes. This expansion and contraction

develop cyclic internal stresses in the structure, leading to fatigue stresses in the chassis that can ultimately lead to failure of the satellite.

Provided items will be (1) side panels and (2) scientific package. Students will need to design a

simple truss style. chassis and perform FEA and design optimisation to develop a unique prototype.
