近年来,汽车设计中所考虑的因素愈来愈多。这些因素包括减轻车重、降低油耗、车身的最佳形状,以及提高安全可靠程度等等。随之而来的设计计算愈来愈复杂。同时,设计师们把注意力转向选用别的结构材料,诸如工程塑料等。这样,放弃金属性能的计算,转而去进行塑料特性的计算,使计算更为复杂。好在汽车工业是采用计算机辅助结构设计来克服这些困难的为数不多的工业部门之一。采用计算机辅助设计方法,可以在有限的时间和资金范围内达到最优设计的目的。尤其通出
In recent years, more and more factors have been taken into consideration in the design of automobiles. These factors include reduced vehicle weight, lower fuel consumption, the best shape of the body, and improve the safety and reliability and so on. The design calculations that follow come more and more complicated. At the same time, designers are turning their attention to other structural materials such as engineering plastics. In this way, to abandon the calculation of metal properties, instead go to the calculation of plastic properties, the calculation is more complicated. Fortunately, the automotive industry is one of the few industrial sectors that employs computer-aided structural design to overcome these difficulties. The use of computer-aided design methods can achieve the optimal design within a limited time and money. In particular, out
