I am going to be a bit busy today in the rush to get closer to finding our hardpoints! Please please let me know if there is anything I should be clearer on - some of these tasks are urging you to begin researching and understanding things that most of the current members do not really even have a great grasp on so let us know if I can help guide your learning.

Prioritize your mental health this week and this weekend!

Today these are the things I want you guys to work on:

In the spirit of trying to be more organized about assignments Ill take a count of which one of these each person touched on.

Everyone:

• Make progress on your master model - then start making the parts for it

• if you would like to because you think it would benefit you / you didnt get to complete it as well as you would have liked then -

  • Finish SRR if you have not - take notes if you must

  • review the questions that were brought up during the suspension portion

  • work on the model mania cading

  • watch the bolted joints video assigned if not have alrdy - take notes

  • watch parra lectures recorded - notes

• make sure you can calculate the radial loads on the bearing - Harshit talked about it at dyn meeting

Carter

• Today / this week please look into kinematics packages and software - you will be working with the CR liaison to get them to help us get software for free to model our suspension - needs to be trailing arm

• I will give you the manuals to dynatune for trailing arm:

• Look into OptimumK software and see if anything tells us that they support the trailing arm w ONE wheel

• Kinematics Software - i uploaded manuals to Sharepoint

• if they cant, look into ADAMS software and take notes on its interface, what the offer, if ppl have any thoughts ab it from a solar pov - the learning curve is very very hard but we dont know why / havent seen the UI yet

• Specializing in new gen: vehicle dynamics

  • what is our ideal degree roll/g lat acceleration aka roll gradient - how relevant is it for solar car and how can we consider it when designing?

  • bump steer x steering members - how can suspension help mitigate this

  • caster x kingpin angle relationship - what do we want to optimize for and what are the different effects to our vehicle dyn that can be achieved from adjustments?

  • explore vsusp and kinematics software options - take notes please I want to know too!

La’akea:

• work on the reference sketch / master model and we will make sure that you understand how and how to make you first part using it

• may meet with composite / TRAVEL TO PICKLE in the last half of workday to see layup / testing process

• Specializing in new gen: composite integration and pushrods

  • understand the loads in the pushrods, what kind of inserts can we use?

  • radial load calculations on the rod ends at either end of the pushrods - benefit from doing the bearing calculations

  • understand composites and MATERIALS - why would we use CF instead of steel - why would we use steel instead of aluminum? - in what loading conditions are these materials strongest and thus when should we use them in what components?

Oliver

• Research manufacturing methods for control arms and methods of bearing inserts - staking or internally grooving for ret rings

• begin CADing a control arm for Daybreak that is 2 inches longer than the previous and can house a retaining ring

  • or can be staked if you understand enough about it

  • read the thread in general slack dyn-collab where we talk about staking bearings

  • the current daybreak CAs are aluminum waterjetted with three rodends - you can try to make the same type of aluminum waterjetted with housing a bearing - I started on front upper

  • but look at the uploaded pics of other teams control arms (solar cars in particular) and see if there are other reliable and manufacturable options - steel tubular may be too difficult bc of how short they still are and figuring out how to insert the rod ends in that case

• Specializing in manufacturing and daybreak:

  • bearing calculations, machining, control arms!

  • loads on control arms, manufacturing methods for control arms, methods of bearing retaining

  • Machining and manufacturing fundamentals - feeds and speeds, tooling, tolerancing

Manas

• Meet with jonathan, and a frame member to talk about your plans for the trailing arm as well as what you guys have learned about it overall

  • if you guys need to - write out a plan and coordinate w each other on what resources you will look at and what tasks or projects you think you might be taking to model a trailing arm suspension

• If you have a good idea of trailing arm mechanics - look a the dynatune manuals for trailing arm - I havent discerned if it is worth is for us to obtain dynatune because it is very hard to use SO I want you to read the manual after understanding what you are optimizing for in a trailing arm and see if dynatune trailing arm would be useful, useable, and addresses all our needs

• Kinematics Software

• Specializing in trailing arm and daybreak

  • hardpoints for trailing arm,

  • shock to be used in trailing arm - coil, travel needed?, any specific spring rate or stiffness recommended for a rear 1 wheel trailing arm?

  • overall architecture of a trailing arm

  • compare trailing arm to swing arm - what are the differences? pros, cons? - this was hard for me to find resources on so do your best to collect some resources
