目前大多数用于人工作业人机工程学评估的数字人体模型的应用都集中在静态姿势的分析上。可用于静态分析的工具包括关节特定强度、关节力矩计算、平衡维护能力和下背压缩或剪切力估计。然而，对于许多任务，由于身体部分或外部物体加速而产生的惯性载荷可能会对身体内部力和组织应力产生重大影响。由于将运动动力学纳入分析的复杂性，大多数用于人体工程学评估的商业软件包不具备包括动态效果的能力。因此，商业人工建模软件包很少为用户提供确定静态分析是否足够的机会。本文的目标是量化使用任何人建模系统的材料处理任务的静态和动态分析之间的差异，以包括运动的影响。对任意模型进行动态人机工程学分析的可行性和可追溯性进行了评估。对静、动分析中的低背弯矩、压缩力和剪力进行了比较。
ABSTRACT Most current applications of digital human figure modelsfor ergonomic assessments of manual tasks focus onthe analysis of a static posture. Tools available for staticanalysis include joint-specific strength, calculation ofjoint moments, balance maintenance capability, and low-back compression or shear force estimates. Yet, formany tasks, the inertial loads due to acceleration of bodysegments or external objects may contribute significantlyto internal body forces and tissue stresses. Due to thecomplexity of incorporating the dynamics of motion intoanalysis, most commercial software packages used forergonomic assessment do not have the capacity toinclude dynamic effects. Thus, commercial humanmodeling packages rarely provide an opportunity for theuser to determine if a static analysis is sufficient. Thegoal of this paper is to quantify the differences betweena static and dynamic analysis of a materials handlingtask using the AnyBody modeling system to include theeffects of motion. The feasibility and tractability ofperforming dynamical ergonomic analysis with theAnyBody model is assessed for the analysis of anasymmetric lifting task. Comparisons between low backmoments, compression and shear forces for dynamicand static analyses are presented.
