From Biomechanical Modeling to Biomechanical Simulation of Load Lifting. KeynoteAddress Presented at the American Society of Biomechanics Annual Meeting. Held on November 15, 1990

摘要

According to the keynote address, the objective of biomechanical modeling is todevelop a model of the body or segment of the body which can accurately predict the kinematics and kinetics of task performance and hence the risk of injury. These models can be either static or dynamic and can be either two or three dimensional in nature. The models require input and must be provided data such as the results of electromyographic studies, muscle strength studies, and anthropometric measurements. These models also need information on external forces applied to the body, displacement time, internal muscle force vectors, passive tissue data, and other facts to enable the researcher to gather good results from using the models. Few human simulation models exist which are capable of predicting the motion pattern a worker may or should follow in the performance of a task. The simulation models differ from biomechanical models in that they provide information about displacement/time relationships as output, while biomechanical models need displacement/time relationship information as input. These models can be combined to achieve the ultimate goal of developing a model capable of accurately estimating the forces acting on the body and predicting the motion patterns which will minimize such stress on the body.
