为缓解轮胎抓地与磨损性能间的固有矛盾,以某205/55R16乘用车子午线轮胎为研究对象,对轮胎胎冠进行仿生设计.采用WALKWAY压力测试系统获取猫前爪动态接地特性,并配合3D激光扫描仪进行逆向拓扑.对猫爪掌垫横截面点云进行多项式拟合并采用相似原理对胎冠进行仿生设计.利用ABAQUS建立模型,对比仿生胎与样胎静载、制动、侧偏工况下接地面积与压力分布.结果表明:仿生轮胎设计可有效增大接地面积,降低峰值接地压力,改善轮胎偏磨损现象,实现轮胎抓地与磨损性能协同提升.

滚动轴承出现局部剥落、点蚀等故障时,会产生周期性的振动冲击信号,通常对此信号进行分析即可诊断出故障的严重程度以及出现的位置.但是,设备工作时往往伴随着较大的噪声,因此冲击信号,尤其是早期故障的振动冲击信号,很容易被噪声淹没.针对此问题,本文提出一种基于恒Q变换与二进制能量权重的CQTBEW算法,首先将振动冲击信号进行恒Q变换分析,获得时频谱矩阵;其次对矩阵进行频率分段处理,在时间轴设置滑移窗口,筛选局部极值并二值化时频谱,向时域叠加获得能量时域信号,进行功率谱分析诊断获得特征频率;最后进行仿真信号与实验信

常见的丝驱动蛇形臂机器人在末端受到外部横向力作用时易发生丝松弛现象,导致丝驱动蛇形臂机器人的构型不可控,这种特性即为被动柔顺特性.为解决被动柔顺问题,首先总结并分析了典型丝驱动蛇形臂机器人关节类型及其结构特点.其次以一种含有典型关节的丝驱动蛇形臂机器人为例,详细分析被动柔顺特性的产生机理,进而提出一种被动柔顺指标.通过研究丝驱动蛇形臂机器人的关节结构参数对被动柔顺指标的具体影响,得到了可避免被动柔顺特性的关节参数设计要求.在此基础上,建立3种不具有被动柔顺特性的丝驱动蛇形臂机器人构节.
