为了提高四连杆机构的设计效率，运用AUTOCAD二维空间运动仿真动态检验行李舱门各个部件和机构之间是否存干涉问题，并在检验干涉的过程中修正该四连杆机构设计参数，直到得到合理的机构设计参数。在满足四连杆机构设计参数合理及满足行李舱门在不同状态的要求下，通过对行李舱四连杆机构的力学分析确定出油气弹簧合理的伸展力大小和铰支点的位置，继而计算出行李舱门开启的最小力，从而获得具有较好运动力学特性的四连杆机构。

In order to improve the design efficiency of four-bar linkage, based on the 2-D AUTOCAD dynamic simulation, the paper conducts tests to verify whether interference exists among each component and mechanism of luggage compartment door. At the same time, the paper also corrects the design parameter during the verifying process and finally gets the reasonable mechanical design parameter. In the condition of obtaining suitable parameters of four-bar linkage and satisfying the requirement of different states of the luggage compartment door, the suitable size of extend force of gas spring and fulcrum position have been ascertained. Then, the minimum opening force of luggage compartment door have been worked out and a four-bar linkage with better dynamic characteristic has been obtained.
