The conceptual stress study model (SSM) is basically a schematic representation of the key elements associated with the study of mechanical forces on the human operator. It has been a useful tool for systematically describing the scope and effects of vibration stress study efforts. The model structure is organized in a hierarchy of four levels established to reflect four different levels of description of human response complexity. In order of increasing complexity, these four classes of responses are biodynamic, physiological, psychophysical, and performance. The model also depicts the internal energy and/or information pathways that are likely to occur in the formation of a response to specified vibration inputs. The present utility of this model is to provide a conceptual scheme to help guide vibration study efforts. It is not a general mathematically predictive model. It could prove useful in pulling together the many-segmented modeling results achieved over the last several years to form a centralized interpretive data base.
概念性应力研究模型（SSM）基本上是与研究作用于人体操作者的机械力相关的关键要素的示意图。它一直是系统描述振动应力研究工作的范围和效果的有用工具。该模型结构按四个层次的层级组织，这四个层次是为反映对人类反应复杂性的四种不同描述层次而设定的。按照复杂性递增的顺序，这四类反应分别是生物动力学反应、生理反应、心理物理反应和性能反应。该模型还描绘了在对特定振动输入形成反应过程中可能出现的内部能量和/或信息路径。该模型目前的作用是提供一个概念框架，以帮助指导振动研究工作。它不是一个通用的数学预测模型。它可能有助于整合过去几年取得的多部分建模结果，形成一个集中的解释性数据库。
