【摘要】 本文介绍了由作者所开发的汽车五项性能预测与模拟软包ＰＳＰＶＤ５的功能、特点、程序总体结构及各主模块特征，并给出国产ＣＡ１４１汽车五项性能计算的部分结果。经多种车型的计算考核表明，该软件系统在微机上运行，具有图文并茂、功能齐全、高效快速、方便实用等特点，可为车辆设计师们创造一个车辆性能控制的计算机应用环境更多还原

【Abstract】 In this paper, a five performance simulation program for vehicle design (PSPVD5) developed by the authors is introduced. It includes PSPVD5′s overall structure,functions, and characteristics as well as the part calculating results of truck CA141,etc. By calculating several vehicles using PSPVD5, it shown that PSPVD5 is plentiful in supplying the materials, complete in function, efficient in design, and easy to use. Installing PSPVD5 in microcomputer, a practical computer environment to control vehicle′s performance can be supplied for the designer.更多还原
