基于 Pro／E的发动机曲柄滑块机构运动仿真分析

摘要

The crank slider mechanism model of engine piston is built based on Pro/E software.The motion simulation is made for the mechanism, the displacement, speed and acceleration curves of slider in the motor process are extracted, the out-put change rules of physical quantity in the process of movement of the slider are analyzed , and the simulation result is con-trasted with the mathematical analysis result,the theoretical analysis is agree with the simulation results.This design method is visualization, accurate and efficient, and has definite engineering application value.%　　运用Pro/E软件创建了发动机活塞的曲柄滑块机构模型，对该机构进行运动仿真，提取运动过程中滑块的位移、速度、加速度变化曲线，分析了滑块在运动过程中各物理量的输出变化规律，并将仿真结果和基于数学分析的结果进行对比，理论分析与模拟结果吻合。该种设计方法可视化强，精确、高效，具有一定的工程应用价值。
