This thesis takes the four-cylinder double-acting Stirling engine as the research key. Based on the Schmidt analysis method, all kinds of flow friction losses and heat losses are analyzed and a model which adapt to the performance of the four-cylinder double-acting Stirling engine is built.

本文以四缸双作用斯特林发动机为研究重点，首先阐述了模拟斯特林发动机的施密特分析法，进而分析了四缸双作用斯特林发动机工作过程中存在的各种流动阻力损失和热量损失，建立了适用于模拟四缸双作用斯特林发动机性能的模型。

In this paper, the marshland of Daxinganling forest region is classified into three kinds, the pass performance of three kings of crawler fire engine, J-50, A531, BFC804 and a kind of two-wheeled forest fire engine of special light-duty HS-8 is studied in theory and test, the calculation formulas of the tangential traction force and the external motion resistance of vehicle are given and the drawbar pull is used as evaluation index.

对大兴安岭林区的沼泽地进行了分类，并对3种履带式森林消防车J-50、A531、BFC804和一种特轻型双轮森林消防车HS-8的沼泽地通过性作了理论与试验研究，给出了切线牵引力和行驶阻力的计算公式，采用挂钩牵引力作通过性评价指标。结果表明，BFC804可以通过重沼泽地，A531和HS-8可以通过中沼泽地，而J-50只能通过轻沼泽地。
