摘要

为了研究斜盘发动机摆盘机构相关参数对发动机动力性能的影响，通过对斜盘发动机摆盘机构相关参数的推导，建立了其设计参数与发动机动力学性能之间关系的数学模型；结合该数学模型，采用控制变量法，研究摆盘机构缸数的变化对输出转速及斜盘质心位移的影响，并进行了Adams仿真分析。结果显示，当选择缸数为自变量时，斜盘倾角从29.93°逐渐减小至14.26°，且缸数为7缸时的转速平均偏差最小，为0.005 4 r/min；斜盘质心在

轴、

轴上的位移平均值也最小，分别为-0.005 9 mm、-0.016 7 mm；在

轴上的位移平均值为0.038 8 mm，虽不是最小值，但偏移幅值更小。结果表明，发动机缸数为7缸、斜盘倾斜角为16.35°的结构时，主轴转速稳定性及斜盘的稳定性均为最优。研究为斜盘发动机的参数设计提供了参考。

Abstract

In order to study the influence of relevant parameters of the swashplate engine pendulum mechanism on engine dynamic performance

a mathematical model which can express the relationship between its design parameters and engine dynamic performance is established through the derivation of relevant parameters of the swashplate engine pendulum mechanism. Combined with the mathematical model

the influence of the change of the number of cylinders of the pendulum mechanism on the output speed and the displacement of the center of mass of the swashplate are studied using the control variable method

and the Admas simulation analysis is carried out. The results show that when the number of cylinders is selected as the independent variable

the inclination angle of the swashplate decreases gradually from 29.93° to 14.26°

and the average deviation of speed is the smallest when the number of cylinders is 7

which is 0.005 4 r/min; the average displacement of the swashplate centroid on

-axis and

-axis is also the smallest

which are -0.005 9 mm and -0.016 7 mm respectively; the average displacement on the

-axis is 0.038 8 mm

which is not the minimum value

but the offset amplitude is smaller. The results show that when the number of engine cylinders is 7 and the inclined angle of the swashplate is 16.35°

the stability of the spindle speed and the stability of swashplate are the best

which provides some reference for the parameter design of swashplate engines.
