Abstract

An analysis of gear transmission on a countinous passive machine (CPM) from the 3-dimensional design has been carried out using Solidworks software. Analysis of the strength of the gear structure is affected by the weight of the patient's arm.Analysis of gear transmission that is affected by the load of the passive arm uses static simulation, by entering the patient's arm load. The facilities used are static simulation with the condition of fixed geometry in the parts related of the shaft, the effect of gravity of 10 m/s2, making mesh, and running simulation.The maximum stress that occurs in gear3 z = 100 is 4.5524e + 006 N/m2, the maximum stress on gear2 z = 80 is 4.81729e + 006 N/m2, the maximum stress on gear100 z = 20 is 9.08982e + 006 N/m2

Abstract

The Fused Deposition Modeling method in the rapid prototyping technique was modified using a paste-shaped material with biocomposite material. One of the correction factors for the printed test specimen results is shrinkage. The paste material used is hydroxyapatite [CA5(PO4)6(OH)2] and tapioca bioplastic is one of the biomaterials that has been widely used in tissue engineering. Besides these materials, sericin is added, which is produced from extracts from silkworm cocoons.The composition of the biocomposite paste used with the ratio of hydroxy apatite and bioplastic was 40:50, 50:50, 60:40, by adding 0.3% sericin to the hydroxyapatite solution. The parameters used in the printing process of the test specimens are the perimeter speed of 60 mm/s, the infill speed of 10 mm/s, and the layer height of 0.45 mm. The design in this test has dimensions of 100mm long, 25mm wide, and 3mm thick. The optimal shrinkage of the test specimens was analyzed using the Taguchi . methodSpecimen printing is done by using additive manufacturing method. The process is carried out using a Portabee three-dimensional printing machine that uses a Fused Deposition Modeling (FDM) system modified to an Aqueous-Based Extrusion Fabrication (ABEF) system. The size of the printed test specimens with dimensions of 100mm long, 25mm wide, and 3mm thick. The comparison of the biocomposite materials used in the composition of hydroxyapatite suspension paste and tapioca starch bioplastics ranged from 40:50, 50:50, 60:40, with the addition of 0.3% sericin hydroxyapatite suspension. The optimal composition of the bioplastic material was analyzed using the method. Taguchi.The results obtained that the optimum composition for shrinkage of the hydroxyapatite and bioplastic compositions was 50:50 with the addition of 0.3% sericin to the hydroxyapatite solution

Abstract

Continuous Passive Motion (CPM) Machine is a therapeutic device that is used to assist the process of therapy and recovery of a patient after having joint surgeryor injury of the ankle. In this research, a CPM machine will be developed for ankle joint therapy. The rotation speed of the CPM machine will be controlled by a DC motor which is used to drive the ankle joint therapy device.Speed control for DC motor is used on a therapeutic device (CPM machine) to determine the level of the therapeutic process; therefore this device can be adjusted to the needs of the patient who will use the therapeutic device. Speed control of the DC motor that will be carried out in this research is using Proportional Integral (PI) control. With the PI control, the result of output will always be compared with the set point value. The result of this comparison will provide an error value, which later the error value will be processed by PI control.The PI values used in this research are Kp 5 and Ki 15.The test results of the CPM movement speed show that the difference between the set point and the resulting movement is 1 RPM. Where the speed tested on this tool is 3 RPM and 5 RPM.  So, the output of this device will be as expected. In brief of this research, a therapeutic device that can be adjusted the rotational speed as expected.
