With Injury Biomechanics and Control as their guide, readers will discover how to design better protective equipment and devices such as helmets, seat belts, and wheelchairs in order to minimize the risk or the extent of injury to people subjected to impact loads.
The first part lays down the engineering foundation, setting forth core principles and techniques, including:
- Fundamentals of impact and shock isolation systems
- Basic optimal shock isolation for single-degree-of-freedom systems
- Optimal shock isolation for multi-degree-of freedom systems
The second part applied the principles set forth in the first part to solve real-world problems, using simple mathematical models that simulate the mechanical response of human bodies to impact loads in order to optimize shock isolation systems.
Injury Biomechanics and Control enables scientists, engineers, and students in mechanical, biomechanical, and biomedical engineering to fully realize the potential of shock isolation methods for the development of protective equipment and devices.
