Study, Based On The Biological Muscle Bionic Drive

With the extensive use of the actuating device in the manufacturing process and research, the limitation of the actuating device, such as complex mechanism, low efficency and inflexibility, becoming more evident. In order to overcome the default of the elcetric power actuating device, it is designing the bionic actuating device, which is more like the bone and muscle of the biotic actuating device, that has been a hot reaserch field. The paper mainly aimes at the configuration of the bionic actuating device, the accuracy control and the choice of the bionic muscle, which are the key problems of the bionic actuating device. The technical scheme is proposed.Firstly, the paper introduces all kinds of the popular actuating device, and then compares their defects and advantages. The bionic actuating device is compared with the actuating devices and the application of the bionic actuating device is analysed.Secondly, the paper introduces some techniques and materials whose mechanisms are more like the biotic muscles and the differences among them is analysed in detail. Then the pneumatic artificail muscle is choosed as the actuator of the bionic actuating device, which is designed by self. The operating characteristic and the control factor of the pneumatic artificial muscle are analysed.Thirdly, the paper analyses the composition of the human arm, explains operating mechanism and builds the model of the bionic actuating device. Because of the complexity of the model, the paper has simplified the model. The bionic actuating device operation is implemented by changing the air pressure of the pneumatic artificial muscles. The influence of the shape change of the pneumatic artificial muscle to the operation of the bionic actuating device is also analysed in the paper and the influence is explained in theory.Fourthly, the control factors of the bionic actuating device are discussed. The paper also proposes how to control these factors.Finally, on the basis of the simplified model, the control accuracy and the angles that can be achieved by the bionic actuating device is analysed through three changes of the air pressure, and the three changes are simulated by the MATLAB. The simulated results are analysed and the different accuracy range is achieved. The simulation results can be applied by the future work.
