为了实现新型汽车悬架横向稳定杆的参数化设计,推导出横向稳定杆尺寸参数的约束公式和橡胶衬套的径向变形量计算公式,在橡胶衬套变形的基础上推导出横向稳定杆端点位移计算公式及其校核公式.运用Excel建立基于CATIA的横向稳定杆参数化模型.并建立Visual Basic窗口,通过编程控制Excel表格相关输入参数,运用Excel实现横向稳定杆相关数值的计算,并将计算值返回到窗口,同时实现参数驱动横向稳定杆三维模型的自动重构.通过有限元分析：稳定杆端部最大位移为83.7 mm,相对偏差为-2.91％;最大Von Mises应力为1 070 MPa,小于许用应力2 884 MPa,从而验证了横向稳定杆参数化设计的正确性.

Parametrization Design of Automobile Suspension Stabilizer Bar

The ennstraint equation of stabilizer bar size parameters anti radial deformation calculation formula of the rubber bushing were derived respe（：tively to realize the parametrization design of automotive suspension stabilizer bar. The displacement calculation formula for stabilizer bar end and verification formula were derived based on rubber bushing deformatinn. Folh）wed by the use uf powerful function of Excel, the model of suspension stabilizer bar was built by CATIA. And setting up the Visual Basic window, using Excel form to control the related input parameters is illustrated. Using Excel to realize the parametric calculation of stabilizer bar, and the calculated value returned to the window, at the same time, automatic re-established 3D model of stabilizer bar was realized. The maximum displacement at the stabilizer bar end was 83.7 ram, the relative deviation was -2.91%. The maximum Von Mises stress was 1 070 MPa, less than the allowable stress of the 2 884 MPa, whit＇h verifies the correctness of parametrization design of stabilizer bar.
