This research shows the analysis forces on the components of the V-12 engine. To complete this research, the thermodynamic combustion process analysis of a V-12 engine was performed to calculate the in-cylinder pressure and temperature profile. These profiles were the boundary conditions for calculating the total force. Furthermore, the friction forces caused by the movements of the components were also calculated by solving the dynamic equations of the engine components. They depend on the engine’s structure and as well as operating characteristics such as load, speed, or lubricant condition. At the full load condition, the engine power reaches the maximum power of 430 kW at 2000 rpm, and the maximum moment is approximately 2350 Nm at 1400 rpm. The maximum total torque on crankpin 1 is 14738 Nm at 5 degrees after the top dead center. Otherwise, the inertia force and the friction force contribute to approximately 9% and 5% of the net torque, respectively. The research results will contribute to optimize the design of the test engine’s components and point out the solution to maintain the durability of engines in the real operation.

这项研究表明了对V-12发动机部件的分析力。为了完成这项研究，对V-12发动机进行了热力学燃烧过程分析，以计算缸内压力和温度曲线。这些轮廓是计算总力的边界条件。此外，还通过求解发动机部件的动力学方程来计算由部件的运动引起的摩擦力。它们取决于发动机的结构和运转特性，例如负载，速度或润滑条件。在满载条件下，发动机功率在2000 rpm时达到430 kW的最大功率，在1400 rpm时最大力矩约为2350 Nm。上止点后5度，曲柄销1上的最大总扭矩为14738 Nm。除此以外，惯性力和摩擦力分别约占净转矩的9％和5％。研究结果将有助于优化测试发动机组件的设计，并指出解决方案，以在实际操作中保持发动机的耐久性。
