We care deeply about the customer, by providing a safe and comfortable environment to make our customers relax and enjoy their time in the car.At Seat Tophat, we are responsible for the development of seat foams, headrest, armrest, upholstery, harnesses, plastics components, and small metal brackets to assure quality of the designs from concept until the end of production phase.
You will be involved in developing some of the safest seats in the whole automotive industry.What you´ll bring
We are looking for candidates with excellent academic records who are open, innovative, driven and team-players. Because of the interdisciplinary nature of our work, we are extending our search to a broad range of competences. If you think that you have what it takes to help us in our journey to deliver safe, human-centric technology, read below on what we do & the various areas we can offer the thesis work in!
Note: Following are the various thesis projects we have currently on offer within Seat Platform and Seat Tophat development areas. Please specify in your application cover letter, project(s) of your interest.Project #1: Study to deepen the understanding of cracks
Background: A seat structure needs to withstand high forces and vibrations that could otherwise generate cracks in the metal.
Objective: Better understand how cracks appear and create design guidelines on how to minimize the risk of cracks appearing.
Scope: A focused study and analysis of the lower cross member in the front seat structure to see what type of forces this part is exposed to and try to provoke cracks.Project #2: Study on vibration signals translated from the vehicle to seat structure
Background: When a new vehicle platform part is developed it needs to protect the integrity of seat structures in different vehicles. This means a general platform vibration signal is generated at an early stage. As the program develops, more detailed information becomes available on each specific car model and thus the vibration signal becomes more unique.
Objective: Gain deeper understanding of vehicle vibrations translated into seats to be able to define a requirement based on most representative vehicle signal.
Scope: A focused study of the front seat structure to see how different types of vibration signals translate into what type of movement of the front seat. Further it is also relevant to understand how relevant generated vibration signals are to a complete vehicle environment compared to fixed rig tests.Project #3: Study on vibration signals on how a vehicle tophat can affect complete seat structure performance
Background: When a new vehicle platform part is developed it needs to protect the integrity of seat structures in different vehicles. This means a general platform vibration signal is generated at an early stage. As a program is developed more detailed information becomes available on each specific car model and thus the vibration signal becomes more unique.
Objective: Gain deeper understanding of vehicle vibrations translated into seats to be able to define a requirement based on most representative vehicle signal.
Scope: A focused study of the complete front seat to see how different vehicle tophats can affect the seat structure performance for different types of vibration signals translates into the front seat.Project #4: Comfort CAE simulations
Background: CAE is providing a good support tool for the development of components through quick loops of verification through computer simulations of various load cases. Now we want to further develop CAE tools to also support Comfort evaluations which today is subjective and requires a lot of resources to do.
Objective: Develop a method to capture comfort aspects of a seat through pressure mapping simulations and correlate that to different foams and upholstery behavior.
Scope: Take a specific seat and use the material specification to generate a model of a seat with the capability to simulate how different bodies deform the seat and define a comfortable pressure mapping.Project #5: SPA2 Front and Rear Seat CAE Correlation method development
Background: CAE is providing a good support tool for the development of components through quick loops of verification through computer simulations of various load cases. But to be able to make engineering judgements of simulations we need to trust the results.
Objective: Develop methods to increase the correlation between CAE models and the physical results.
Scope: Take a specific load case and work with comparing physical tests and try to recreate the same behavior in a CAE model.Project #6: Predict wear & tear on Seat Upholstery with digital tool
Background: In current development we need to rely on our gained knowledge from previous projects and physical testing or even wait for customer complaints when it comes to wear/tear. When developing new concepts/designs on seat upholstery it is time consuming to develop physical samples for testing, and not enough time to wait for customer input.
If the upholstery could be simulated on the complete seat in a digital environment, with correlating material properties, input can be collected faster and help predict design consequences.
Objective: Find a way to simulate potential wear/tear and design consequences on upholstery on complete seat (modelling in digital environment) including material properties (foam hardness, different surface materials and seams) to avoid late changes which causes cost, time and quality issues.
Scope: Aim is to identify potential digital tools on the market and propose updates of existing tools. Make samples correlating to tool.Project #7: Interchangeable/adaptable fixture for Rear Seat
Background: Test rigs are used in different test scenarios, and new rigs are built for each program which is not cost or environmentally effective.
Objective: With an adaptable fixture we can gain time, save cost and re-use material.
Scope: Define prerequisites and design a model for an adaptable fixture and prepare for a prototype. Collaboration with test labs needed.Project #8: Integration of Headrest into Armrest in Rear seat
Background: Aim is always to understand and fulfill our customer demand, so how to increase the arm comfort and support in low spec cars in rear seat.
Objective: With a longer armrest in the rear seat the comfort and support can be increased.
Scope: Benchmark of competitors, design a concept of an integrated Headrest into Armrest, prepare for prototype and comfort evaluation.Project #9: Simulation to predict physical H-point in Seat
Background: H-point is a legal requirement that is dependent on many different factors of the seat (comfort requirement, foam density/hardness, upholstery characteristics, dummies etc).
Objective: aim is to find a correlation between simulation and physical parts so in the end we can reduce physical testing to save time and cost.
Scope: Establish simulation method to predict H-Point in Seat – with variables – Upholstery material, Foam density and hardness, comfort components in package. etc. So that physical testing can be reduced.DurationDoes this sound like your next challenge?
