摘　　要：车辆制动性能计算是车辆设计的重要组成部分,在计算过程中呈现出参数多、公式多、计算量大的特点,尤其是在选出最优设计方案时需要进行多次反复计算,采用手工计算和计算机编程计算已无法满足车辆制动性能计算的需求。本文基于计算机辅助设计的思想,借助MathCAD计算软件中自带定制计算模版方法 ,实现了某地铁车辆制动性能计算模版的定制,并验证了该方法在车辆制动性能计算中的可行性。相比上述两种计算方法 ,该方法可以简化计算过程、增强可视性、实现自动化计算、降低对设计人员的要求,同时可以直接生成计算分析报告,便于企业产品数据管理。Vehicle braking performance calculation is an important part of vehicle design. There are lots of parameters, formulas and large amount of calculation in the process of calculation, especially needing recalculation before choosing the optimal design scheme. It cannot meet the needs of vehicle braking performance calculation to use manual calculation and computer programming calculation. This paper based on the idea of CAD implements template customization of a metro vehicle braking performance calculation with the method of template customization in MathCAD, and verifies the feasibility of this method in the vehicle braking performance calculation. Compared with the above two kinds of calculation method, this method can simplify the calculation process, enhance visibility, calculate automatically and reduce the demand for designers as well as can create directly analysis report of calculation and be advantageous for the data management of enterprise products.
