Simulation and study of joint clearances has usually focused on appropriate simulation strategies and their validation against experiments. The effect of joint clearances on the output of a mechanism has been usually evaluated qualitatively. The relative importance of different joints in a mechanism in producing deviation from the output of an ideal mechanism has not been studied. This work identifies the appropriate statistical measure for quantifying this deviation and uses it to rank the joints of one degree of freedom multi-loop planar mechanisms. The inversions of six-bar mechanism have been studied through ADAMS simulations involving different clearance sizes and speed of crank. A trend in clearance location ranking has been identified which can probably be extended to planar mechanisms of higher complexity.

关节间隙的仿真和研究通常集中在适当的仿真策略及其对实验的验证上。通常已经定性地评估了关节间隙对机构输出的影响。尚未研究机械中不同关节在产生与理想机械输出的偏差时的相对重要性。这项工作确定了量化此偏差的适当统计量度，并使用它对一个自由度多环平面机构的关节进行排名。通过涉及不同游隙尺寸和曲柄速度的ADAMS仿真研究了六连杆机构的反转。间隙位置排序的趋势已经确定，可以将其扩展到复杂性更高的平面机制。
