Abstract

A rigid multi-body dynamic model of an elephant was developed for motion analysis during tilt-lifting.  The elephant lifting to standing position is required by veterinarians to perform surgery and bedsores treatment.  The elephant mechanism dynamic model (EMDM) was developed by simplifying the skeleton to simple straight linkages connected by joints.  The model consisted of 10 bones and 9 joints.  A mechanical harness model (MHM) was developed.  Two harnesses were attached to the tilt-frame mechanism model (FMM) and the EMDM; this assembly became the elephant dynamic during tilt-lifting model (EDTM).  The developed EDTM permitted us to observe the displacement, velocity, and acceleration responses at any location on the elephant.  The model allowed the virtual study of the motion, and avoided the real elephant testing; thus, the cost, time, and resources were reduced and no conflict with the animal experimental ethics.  The simulation was found to be a valuable tool for engineers to design a suitable elephant bed.  It permitted us to observe the operation, safety, and precaution of the equipment.
