The equations for wheelchair caster wheel shimmy are presented along with experimental data. The report includes the theory and performance of single wheel casters for a variety of tires, and a new design for wheelchair casters using a grooved dual-tread tire or co-rotating caster wheels. The dual-tread tire was found to significantly inhibit caster shimmy. The turning resistance due to a grooved caster wheel tire with a 1/2-inch groove was found to be 10 percent greater than for an ungrooved caster wheel tire. The analysis includes the methodology and the results of experiments developed to measure the sliding friction turning moment of the wheelchair caster wheel. A number of commercial wheelchair caster wheels were tested and the results for shimmy are presented.
文中给出了轮椅脚轮摆动的方程以及实验数据。该报告涵盖了各种轮胎的单轮脚轮的理论和性能，以及一种采用带槽双胎面轮胎或同向旋转脚轮的新型轮椅脚轮设计。结果发现，双胎面轮胎能显著抑制脚轮摆动。带有1/2英寸凹槽的带槽脚轮轮胎的转向阻力比无槽脚轮轮胎大10%。分析内容包括测量轮椅脚轮滑动摩擦转动力矩的实验方法和结果。对一些商用轮椅脚轮进行了测试，并给出了摆动测试结果。
