摘　　要：提出一种由3D打印技术和硅胶浇筑技术相结合的锯齿状气动软体执行器,对执行器的弯曲角度与气压的关系进行数学建模,通过单轴拉伸实验对材料参数进行测定,利用ABAQUS软件对影响执行器弯曲性能的因素进行有限元仿真,并对不同因素参数组合下的执行器弯曲位姿和运动区域进行分析,从而获得各因素综合作用下的最佳参数组合。搭建实验平台,对最佳参数下的执行器弯曲角度和运动区域进行实验测定,验证了建模的准确性。A zigzag aerosoft actuator was proposed by combining 3D printing technology and silica gel casting technology.Mathematical modeling was conducted on the relationship between the bending angle and air pressure of the actuator.Material parameters were measured by uniaxial tensile test,and the factors affecting the bending performance of the actuator were simulated by ABAQUS software.The bending pose and motion area of the actuator under the combination of parameters of different factors were analyzed,so as to obtain the optimal parameter combination considering the comprehensive effects of various factors.An experimental platform was built to test the bending angle and movement area of the actuator under the optimal parameters to verify the accuracy of the modeling.
