Sensitivity Analysis Of Hill Muscle Parameters, Janet Brelin-Fornari, Paras Shah, Mohamed El-Sayed Oct 2018

Sensitivity Analysis Of Hill Muscle Parameters, Janet Brelin-Fornari, Paras Shah, Mohamed El-Sayed

Janet Brelin-Fornari

A computational, rigid body model of a 50th percentile male head and neck utilizing 15 Hill Muscle pairs is used to study the sensitivity of Hill Muscle Model parameters. A 15g linear acceleration is applied within the transverse plane at the lowest vertebral level of the neck (T1). The resultant linear acceleration of the head is analyzed. In response is minimally affected. The peak accelerations did change, and in the case of varying muscle activation, the peak acceleration changed significantly, 36%. Each of the other parameter variations affected the peak acceleration of the head by less than 5%. Overall ...

Crash Safety in the Introductory Physics Lab Abstract In the field of vehicle occupant protection and crash safety, the Deceleration Sled offers researchers a controlled, repeatable, and relatively cost-effective means to test interior parts such as safety restraint systems. The sled can accelerate a 2000 lb payload to achieve a speed of 40 mph before a hydraulically controlled deceleration models the deformation of the vehicle structure during a crash. Understanding the dynamics of the sled and interpreting test results incorporates many of the core concepts of a first course in introductory physics. This application of physics principles is the inspiration ...


Development Of Nhtsa’S Side Impact Test Procedure For Child Restraint Systems Using A Deceleration Sled : Part 1, Janet Brelin-Fornari, Sheryl Janca Oct 2018

Development Of Nhtsa’S Side Impact Test Procedure For Child Restraint Systems Using A Deceleration Sled : Part 1, Janet Brelin-Fornari, Sheryl Janca

Janet Brelin-Fornari

This report presents the results of the research and development of the child seat side impact tests performed at Kettering University’s Crash Safety Center for NHTSA. The tests were conducted using a deceleration sled. The objective of this testing was to obtain data for the development of a side impact test procedure for child restraint systems.


Development Of Nhtsa’S Side Impact Test Procedure For Child Restraint Systems Using A Deceleration Sled : Part 2, Janet Brelin-Fornari, Sheryl Janca Oct 2018

Development Of Nhtsa’S Side Impact Test Procedure For Child Restraint Systems Using A Deceleration Sled : Part 2, Janet Brelin-Fornari, Sheryl Janca

Janet Brelin-Fornari

This report presents the results of the continued research and development of child seat side impact tests using the deceleration sled at Kettering University’s Crash Safety Center. The objective of this test series was to gain further insight into the sensitivity of the side impact test fixture response. Test variations included speed of impact, weight of the fixture, and impact characteristics. Additionally, 20 child restraint system (CRS) specific tests were conducted using a fixed set of test parameters.


A Study Of Muscle Activation In A Mathematical Model Of The Human Head And Neck, Janet Brelin-Fornari, A. Arabyan Oct 2018

A Study Of Muscle Activation In A Mathematical Model Of The Human Head And Neck, Janet Brelin-Fornari, A. Arabyan

Janet Brelin-Fornari

A model of the human head and neck that incorporates active and passive muscles is utilized in the analysis of non-impact loading in high “g” environments. The active muscles have the capability to be activated partially and in different combinations.The model is implemented in MADYMO using lumped parameters and Hill muscles. A comparison of simulation results with experimental data, generated by the Naval Biodynamics Laboratory (NBDL) for neck flexion and rebound, shows excellent agreement for a 15g impulsive load.

Internet Enabled Remote Driving Of A Combat Hybrid Electric Power System For Duty Cycle Measurement, Jarrett Goodell, Marc Compere, Wilford Smith, Mark Brudnak, Mike Pozolo, Et Al. Feb 2018

Internet Enabled Remote Driving Of A Combat Hybrid Electric Power System For Duty Cycle Measurement, Jarrett Goodell, Marc Compere, Wilford Smith, Mark Brudnak, Mike Pozolo, Et Al.

Marc Compere

This paper describes a human-in-the-loop motion-based simulator interfaced to hybrid-electric power system hardware, both of which were used to measure the duty cycle of a combat vehicle in a virtual simulation environment. The project discussed is a greatly expanded follow-on to the experiment published in [1,7]. This paper is written in the context of [1,7] and therefore highlights the enhancements. The most prominent of these enhancements is the integration (in real-time) of the Power & Energy System Integration Lab (P&E SIL) with a motion base simulator by means of a “long haul” connection over the Internet (a geographical ...
