查询词典 radio-opacity

The test results show that, the drag bar pull and efficiency coefficient is increasing with the wheel width and diameter. The draw bar pull increased with the rug height, but the efficiency coefficient reduces when the slip radio is bigger than 20%. The draw bar pull and efficiency coefficient will reduce with the rug distribution incereases when the rug distribution is more than 20%.

结果表明，当增大驱动轮宽度和直径时，其挂钩牵引力和效率系数都呈增大趋势；增大驱动轮的轮刺高度，挂钩牵引力增大；当滑转率小于20%时，效率系数随着轮刺高度的增大而增大，而当滑转率大于20%时，效率系数随着轮刺高度的增大而减小；增大驱动轮轮刺密度时，其挂钩牵引力和效率系数随之先增大后减小。
