Electronics and Wiring

The wiring harness is cost as a number of connectors of a certain style, each interconnected by a number of wires of a certain type. The electrical system is composed of three wiring types.

8.1 Signals - Inputs to the control system such as wheel speed, mass airflow or the position of a driver toggle switch.

8.2 Controls - Control system outputs. These can be digital signals, pulse width modulated or voltage outputs.

8.3 Power - Wires carrying current for vehicle distribution or actuators. These include vehicle power from the battery, engine starter, solenoids, motors etc.

8.4 Additionally, the following terms will be used for the Cost Tables:

APPENDIX S – 2 STANDARD PART NUMBERING

1 All assemblies and parts in the BOM must have a part number using the following convention: Competition Code – Date Code - Car Number – System Designation – Base Number – Suffix

1.1 Competition Code – A code for the competition entered. Refer to A2.6.

1.2 Date Code – Last two digits of the year of the event.

1.3 Car Number – A three (3) digit number assigned to the car for the specific event

1.4 System Designation – A two (2) letter code for the system under which the part is associated. These can be found in Appendix C-3.

1.5 Base Number – Five (5) digit numbers assigned at the student’s discretion. For assemblies this becomes

a four (4) digit number with preceding character of “A”.

1.6 Suffix – Two character code showing part change history. These are provided for student use only so if

desired all can be “AA”.

1.6.1 First character refers to the part design revision level.

1.6.2 Second character refers to the part process revision level.

1.7 For example, a part entered into the chassis section for car number 27 competing at an event with code

“FSAEM” that the students have decided is part one would be:

FSAEM – 08 – 027 – CH – 00001 – AA

1.8 The same part, after significant design changes would become: FSAEM – 08 – 027 – CH – 00001 – BA

The differential assembly that the students have decided is the third assembly for the Engine & Drivetrain group would be:

FSAEM – 08 – 027 – EN – A0003 – AA

1.9 In the printed version of the Cost Report the competition code, date and car number fields of the part numbers do not need to be printed. They do need to be included in the digital files submitted. The event code and car numbers are for SAE use when the different digital files are combined into the master database.

2 All fasteners in the BOM must have a part number using the same convention as parts. All fasteners use

system code “FS” even though they are included in the BOM under the part and assembly where they are used.

APPENDIX S – 6 PRESENTATION JUDGING

SCHOOL CAR NUMBER

Score the following categories on the basis of 0-10 points each according to the following scale (any number or fraction along this scale may be used).

0.0	=	inadequate or no attempt
2.5	=	attempted but below expectation
	=	average or expected
7.5	=	above average but still lacking
	=	excellent, perfectly meets intent

CONTENT: Were the concepts presented appropriate and adequate to explain how the car meets the intent of the customer? Were enough technical details presented without being boring?

ORGANIZATION: Were the concepts presented in a logical order progressing

from basic concept and showing how the engineering accomplished the concept? Was it clear to the audience what was to be presented and what was coming next? Were distinct

introduction and overviews as well as summary and conclusions given?

VISUAL AIDS: Were visual aids used or clear visual references made to the car? Were the illustrations visible for all of the audience?

DELIVERY: Did the presenter speak in a clear voice? Did the presenter show

enthusiasm and promote confidence in the technical aspects? Did he maintain eye contact?

QUESTIONS: Did the answer illustrate that the team fully understood the question? Is there doubt that the team understood the answer? Did the team promote complete confidence in their response to the questions?

TOTAL = PRESENTATION POINTS (50 points maximum)
