Abstract

The paper presents the development process of the free-piston generator. During the study, we developed the generator concept taking into account modern trends in the field of free-piston generators. Based on the selected concept we performed the calculation of the generator units and subsystems and created a 3D model. While developing the 3D model of the generator we used 3D finite element methods to calculate the cooling system and mechanical strength in the model and, finally, created design documents. Besides, the control algorithms and control system were developed. As soon as the power generation system was produced, the installation and startup works were held. In order to perform the testing of the free-piston power generator, we constructed a test-bench, which provided the generator with air, fuel, oil and coolant. It also contains a powerful active electric load. During the tests, the generator achieved the output power of 16.87kW. The testing results allow choosing the future ways for construction development in order to increase and upgrade the characteristics of the free-piston generator.
