This article contains information about the FSAE cockpit design. Formula SAE (FSAE) is an international formula car competition held by the Society of Automotive Engineers (SAE) and participated in by students from various universities. They compete to design, build, and race small, open-wheel, single-seat formula cars. In this article, you will learn about the application of ergonomics in the FSAE cockpit design.
Application of Ergonomics in FSAE Cockpit Design
In the FSAE rulebook, there are several rules that refer to driver safety and ergonomics in the context of FSAE cockpit design. The following are guidelines in the FSAE rulebook that refer to cockpit design ergonomics:
1. The vehicle must be able to accommodate drivers with body anthropometric measurements ranging from the 5th to 95th percentile for males.
Vehicles must be able to accommodate drivers of various body sizes, ranging from normal body sizes to the most unusual ones, using the 5th and 95th percentiles.
2. The driver’s head and hands must not come into contact with the ground in any position when the vehicle is overturned.
The dimensions shown in the image are those that each team must adhere to when designing their vehicle cockpits. However, in addition to meeting these dimensions, this regulation also aims to prevent drivers from coming into contact with the ground when the car is upside down.
3. Cockpit dimension inspection by creating a driver mold using anthropometric data from men with body sizes in the 95th percentile.
This template will be used during technical inspections by car inspectors when cars are about to participate in racing events. The purpose of this inspection is to ensure that the instruments in the cockpit are within reach of the driver.
4. Inspect the cockpit dimensions by creating templates for the upper opening and foot opening in the cockpit.
This template will be used during technical inspections by car inspectors when cars are about to participate in races. The purpose of this inspection is to ensure that the dimensions of the cockpit openings comply with existing regulations. Another function of these dimensions is to make it easier for drivers to exit the vehicle, in accordance with regulations stipulating that drivers must be able to exit the car within a maximum of 5 seconds.
Anthropometric Measurements Used in FSAE Cockpit Design
After understanding the application of ergonomics in FSAE cockpit design, you must also know what anthropometric measurements are used in designing an FSAE cockpit. This is important so that you have definite size parameters when designing an FSAE car cockpit. In addition, this ensures that your FSAE car design complies with all regulations and also ensures that the driver is safe and comfortable when driving your car design. Therefore, the following are the anthropometric measurements used in designing the FSAE cockpit:
| No. | Dimensi |
| 1 | Seated Knee Length |
| 2 | Sitting Knee Height |
| 3 | Arm Forward Reach Length |
| 4 | Rear Driver Seat Angle |
| 5 | Shoulder Height in Sitting Position |
| 6 | Eye Height in Sitting Position |
| 7 | Height in a Sitting Position |
| 8 | Driver’s Perspective Viewing Angle |
| 9 | Driver’s Seat Angle |
The anthropometric measurements above can be obtained based on measurements taken from all individuals with certain criteria. Meanwhile, the angle measurements above were obtained based on measurements taken until the optimal angle measurement was finally obtained.
Get Anthropometric Measurements to Achieve an Ergonomic and Precise Formula SAE Cockpit Using Anthropometric Chair!
Anthropometric chair are specially designed to accurately measure 34 anthropometric dimensions of the body. Anthropometric chair are already used in various fields, ranging from education, sports science laboratories, the aviation industry, to the military, which have entrusted the process of measuring human anthropometry using anthropometric chairs. So, why choose an anthropometric chair?
- The only anthropometric measuring device that guarantees precise measurement results.
- Can support a wide range of human body measurement needs.
- A measuring device with a sturdy frame and durable materials that are not easily damaged.
- A measuring device with large dimensions that can be used by everyone.
