摘要: This paper describes a methodology for the sensitivity analysis and optimization of planar constrained mechanical systems. Direct differentiation methods finite difference techniques have been used in design calculations. The process is developed within framework mathematical programming techniques. equations were constructed symbolically, subsequently integrated dynamic motion solved simultaneously. Some examples are to demonstrate use including crashworthiness problem, where plastic hinge concept has model deformations vehicle structure during impact.
