摘　　要：针对云梯车的作业高度和梯架系统的整体性能要求不断提升的现状,运用CATIA和ANSYS workbench软件,探讨了一种预应力碳纤维有限元仿真方法,结合云梯车的工况,运用预应力碳纤维加固技术进行优化,对梯架结构进行静力学和模态对比分析;通过对比优化前后的最大应力、最大位移和1~6阶模态固有频率,验证了该优化方案的有效性,提升了云梯车的整体稳定性和安全性。As the requirement of performance and the operation height of ladder system is rising quickly, prestressed carbon fiber reinforcement technology can be very useful. And static analysis and modal of ladder structure are compared using finite element method by CATIA and ANSYS workbench in consideration of working conditions. The validity of this scheme is verified by comparing maximum stress, maximum displacement and one to six order natural frequency with and without prestressed carbon fiber, the stability and safety of ladder system is improved.
