The article presents the study on the driveline experimental design, basic formulas, defining function selected: the torque of the drive motor, the experimental factors: braking torque braking device, engine speed, driveline length, bend angle driveline. A brief description of the equipment, which is a stand, comprising a motor technology transmission driveline, the loading apparatus which are connected in series, and the loading device is hydraulic, comprising: a hydraulic pump, a choke, a filter, a pressure gauge, safety valve, tank, heat exchanger. The design of the proposed stand allows you to explore the driveline of different sizes at different angles of knee driveline. The stand is characterized by simplicity of design, a large range of parameters of loading and ease of setup thanks to the movable frame and vernier, calibrated in units of angle fracture driveline. The stand has a number of advantages: the test driveline while avoiding overheating of the braking system by cooling the working fluid, the improvement of operating conditions by providing a smooth regulation of the braking torque. To control the set parameters testing regimes instrumentation: strain gauges as gauges torque and braking moments, as a recording device using a dual-channel oscilloscope was used. The strain gauges were calibrated in torque and braking moments units empirically using technological devices. The task of the experiment is to find the optimal conditions driveline operation, namely the determination of the maximum efficiency of the driveline depending on the selected length and angle fracture driveline. The above method of design of experiments is designed for experimental studies of various drivelines with various types of bearings. Getting a polynomial regression model, the objective function - torque on the selected constructive-regime parametres of driveline allow further use of search methods the minimum values of the objective function, and, consequently, the efficiency of the transmission and corresponding to these values of constructive-regime parameters, allowing in the future to design phase of such programs to assign them reasonably, thus reducing design time frame while improving the quality of the design decisions, and to use significantly save energy while improving the transmission resource.
Keywords: experimental design, driveline, efficiency, needle bearings, testbench.
