The design of the power unit is an important link which cannot be ignored, so you know what is the specific design process? The main factors which should be paid attention to? First, we need to complete hydraulic calculation and power system, and to determine the type and specification of the engine. Then on the basis of calculation results of the hydraulic system, at the same time refer to the engine manufacturer in the product library existing products, choose to meet the demand of power unit size, especially in highly demand engine products.
The next step is to consider the actual situation, the reasonable design of the power unit mounting bracket and the arrangement of the parts. Are generally according to the mounting bracket, and the structure characteristics of the engine, engine installation using suspension, engine support to three, one in the fan end support, the other two by transfer case two leg support, and the transfer case connected to the engine flywheel shell. Hydraulic oil pump through the coupling connected to the engine flywheel transfer case, to be used for engine power output.
Complete the parts after decorate, also need to be adjusted, the appropriate and proper optimization structural strength on the mounting bracket. Such as through each component in the power unit in the mounting bracket arrangement in 3 d modeling, to have a mutual interference between the parts, influence use, not easy to maintain parts position adjustment, especially for the engine cooling system through the adjustment and test of each component can play to their respective functions in the mounting bracket.
Normally, after the components are fixed, and then combined with the force of the whole and the parts of force and the vibration of the power unit, the finite element analysis was carried out on the mounting bracket, for some of the stress concentration location is optimized and reinforcement, thus ensuring the intensity of the use of the power unit.
