摘　　要：针对不同接触表面形态的热传导特性,采用温度触觉传感器进行了表面形态的识别分析.讨论了表面形态对接触热传导的主要影响因素,对不同条纹间距、不同条纹深度、不同条纹占空比表面下传感器的温度触觉响应进行了ANSYS仿真,得到了传感器的温度响应规律.仿真分析表明:条纹深度d、条纹占空比p是表面形态的主要识别因素,对于温度分辨率为0.1℃的传感器,对d的分辨率可达到0.33mm,在p小于0.7的范围内对p的分辨率可达到0.1.并对波纹、粗糙、光滑3种表面形态进行了试验与仿真对比.结果表明,采用的温度触觉传感方法能较好地识别物体表面形态差异.According to the heat conducting characteristics of different interface morphologies,identification of surface morphologies are analyzed based on a thermal tactile sensor. The main influencing factors on heat conduction by interface morphology are discussed. The sensor's temperature tactile responses on surfaces in different stripe spacing,different stripe depth,different stripe duty were simulated with ANSYS. Simulation analysis indicates that the stripe depth d and the duty cycle p are the major identification factors. With the sensor of temperature resolution of 0. 1 ℃,the d resolution can be up to 0. 33 mm,the p resolution can be up to 0. 1 when p is less than 0. 7. Experiments in ripple,rough,smooth surface morphologies were carried out and compared with the simulations. The results show that the temperature tactile method can identify differences in surface morphology.
