摘要: 为了分析爬壁机器人的吸附性能及优化运动切换策略,建立了一种双框架结构爬壁机器人的吸附结构,采用真空技术分析了有效抽速、流导、泄漏等影响机体吸附能力的主要因素。通过理论分析和实验对吸盘漏率和吸附系统切换策略进行了研究,得到了3种情况下的吸盘漏率参数值与吸盘的响应和释放曲线以及吸盘组切换时的压力动态过程曲线。提出了一种有效的吸盘动态吸附性能分析方法,研究了吸盘动态切换的过程。为真空系统吸附性能的分析和运动切换策略优化提供了直观而有效途径。Abstract: In order to analyze the adsorptive ability and optimize the transition switching strategy for a wall-climbing robot, the adsorption structure of vacuum absorption for a wall-climbing robot is established. The major factors of the effective pumping speed, conductance,leakage that affect adsorption capacity of the robot are analyzed by using vacuum technique. The leak rate of the sucker and the switching strategy of adsorption system are designed by theoretical analysis and experiment respectively. Then the leak rate's parameters of the sucker are calculated. The val-ues of the leak rate, the response and release curves, and the pressure behavior curves of the switching action of the suckers under three circumstances are given respectively. The effective analyzing method of leakage rate is pro-posed, and the process of dynamic switch is studied. An intuitive and effective way to analyze the adsorptive ability and optimize the transition switching strategy for a wall-climbing robot is provided.
