Seat Design Studies

Kettering Univ-Santhosh Sivan Kathiresan
Kettering Univ.-Raghu Echempati
  • Technical Paper
  • 2020-01-1101
To be published on 2020-04-14 by SAE International in United States
In this paper, further studies have been carried out on the analysis and effect of certain design modifications on the structural integrity of an automotive seating rail structure. Automotive seating is one of the important component in the automotive industry due to their main function to carry the weight of passenger as well as to sustain the vibrations from the road. The seat structures are assembled to carry other important components such as side airbag and seatbelt systems. The entire seating is supported firmly and attached to the bottom bodywork of the vehicle through the linkage assembly called the seat rails. Seat rails are adjustable in their longitudinal motion which plays an important role in giving the passengers enough leg room to make them feel comfortable. Therefore, seat rails under the various operating conditions such as forward and normal positions should be able to withstand the complete weight of the human and the associated loads due to vibrations. In this paper, some of the functional requirements such as strength, stiffness, durability and crash performance are…

ROBUST SENSOR FUSED OBJECT DETECTION USING CONVOLUTIONAL NEURAL NETWORKS FOR AUTONOMOUS VEHICLES

Kettering Univ-Sriram Jayachandran Raguraman, Shruti Gotadki
Kettering Univ.-Jungme Park
  • Technical Paper
  • 2020-01-0100
To be published on 2020-04-14 by SAE International in United States
Nowadays, the proliferation of research on the autonomous vehicles and the Advanced Driver Assistance System (ADAS) has resulted from the need for intelligent and safer mobility. Environmental perception is considered as an essential module for autonomous driving and ADAS. In the object detection problem, deep Convolutional Neural Networks (CNNs) become the State-of-the-Art with various different architectures. However, the performances of the existing CNNs have dropped when detecting small objects in distance. To deploy the environmental perception system in real world applications, it is important that the perception system achieves the high accuracy regardless the obstacle sizes, the distances, and weather conditions. In this paper, a sensor fused system for object detection, tracking and classification is proposed by utilizing the advantages of both vision sensor and automotive radar sensor. Data from on-vehicle radar sensor and camera sensor are processed in real time simultaneously. The proposed system consists of three modules: 1) the Coordinate Conversion module converts the radar coordinates into the image coordinate system. 2) Multi Level-Multi Region detection system based on the deep CNNs. The…

Automated 3-D Printing Machine Bed Clearing Mechanism

Kettering Univ-Dalton Whitten, Jason Dietrich, Matt Donar, Colin Donar
Kettering Univ.-Raghu Echempati
  • Technical Paper
  • 2020-01-1301
To be published on 2020-04-14 by SAE International in United States
The work presented in this paper is based on the senior capstone class project undertaken by the student authors at Kettering University. The main aim of the project was to design an automated bed clearing mechanism for the Anet brand A8 3-D printer. The concept behind the idea was to allow everyone with this brand of printer to be able to print multiple prints without human interaction. The idea started out as a universal bed clearing mechanism, for most brands of 3-D printers. Upon researching into the many different styles and designs of printers, it was apparent that the designs differ too much from each other in order to create a universal product. The student team decided to aim for the most common style of 3-D printer, which the team also had a model to test the design. Due to the size of our team (number of members), they were split in to two sub-teams in order to explore two separate designs and develop the design and testing on both of the designs. Their designs…

Design and Implementation of a Sequential Manual Gearbox in a Baja SAE Vehicle

Kettering Univ.-Eric Stuckey, Arnaldo Mazzei, Jennifer Bastiaan, Gregory Davis
  • Technical Paper
  • 2020-01-0428
To be published on 2020-04-14 by SAE International in United States
Baja SAE is one of the SAE International Collegiate Design Series (CDS) competitions focused on the design of off-road vehicles by teams of engineering students from participating educational institutions. It is a well-established series that is currently in need of a new transmission with greater mechanical efficiency, to take full advantage of the low power of the Briggs & Stratton spec engine that is mandated by the rules. Powertrain designs utilizing a Continuously Variable Transmission (CVT) have become the standard, primarily because of their ease of use in the vehicle assembly process and their simplicity of operation. With no need for manual shifting of the transmission, any student can navigate the vehicle through a competition course. Conversely, the tuning of a CVT is complex, and durability is poor, especially under the often wet and dirty conditions of the Baja SAE series. While there are a few teams using manual transmissions, these designs are typically heavier, less efficient, and prone to failure due to poor implementation. In this work, a Sequential Manual Gearbox (SMG) is investigated…

Characterizing the Safety of Automated Vehicles: Book 1 - Automated Vehicle Safety

Kettering Univ.-Juan R. Pimentel
  • Progress In Technology (PT)
  • PT-203
Published 2019-03-07 by SAE International in United States
Safety has been ranked as the number one concern for the acceptance and adoption of automated vehicles since safety has driven some of the most complex requirements in the development of self-driving vehicles. Recent fatal accidents involving self-driving vehicles have uncovered issues in the way some automated vehicle companies approach the design, testing, verification, and validation of their products. Traditionally, automotive safety follows functional safety concepts as detailed in the standard ISO 26262. However, automated driving safety goes beyond this standard and includes other safety concepts such as safety of the intended functionality (SOTIF) and multi-agent safety. Characterizing the Safety of Automated Vehicles addresses the concept of safety for self-driving vehicles through the inclusion of 10 recent and highly relevent SAE technical papers. Topics that these papers feature include functional safety, SOTIF, and multi-agent safety. As the first title in a series on automated vehicle safety, each will contain introductory content by the Editor with 10 SAE technical papers specifically chosen to illuminate the specific safety topic of that book.

Fundamentals of Integrated Vehicle Realization

Kettering Univ.-Mohamed El-Sayed
  • Book
  • R-436
Published 2017-09-25 by SAE International in United States
Fundamentals of Integrated Vehicle Realization is a unique and solid contribution to the subject of product development, centered on the automotive industry. Automotive manufacturers and suppliers are under pressure to transform themselves and deliver a higher level of product refinement coupled with more functionality. This could lead to the sprouting of organizational structures not in alignment with the required product development phases. Consequently, many product development initiatives may be cancelled or dropped at later stages despite all the efforts and financial investments. Therefore, it is vital that organizational unity be always intact during any transformation. A highly effective organization should always act as one cohesive entity dedicated to serving the customer with creative aptitude, integrative skills, analytical thinking, and synergistic management. Written by Dr. Mohamed El-Sayed, director of the School of Engineering Technology at Eastern Michigan University, Fundamentals of Integrated Vehicle Realization addresses an essential need for deep knowledge in the realm of vehicle development process, from idealization to market launch. The book covers realization process phases, process and vehicle characteristics and attributes, front-end innovation,…
