某高机动雷达天线阵面要求举高8．5m，为此设计了两种可行的高架举升机构，一种是双级杆折叠举升机构，另一种是单级杆平行四连杆举升机构。运用计算机仿真分析技术，在满足举升高度和运输高度的前提下，以自重、刚度、强度为目标对举升机构系统进行优化设计。对样机进行实物测试以验证设计的正确性。为后续有限元分析的前、后处理提供了可靠的依据。

Since the antenna array of a highly mobile radar is required to be elevated to 8.5 m, two types of elevating mechanism are designed, one is two-stage-beam folded elevating mechanism, the other is single- stage-beam and parallel-four-rod elevating mechanism. Computer simulation technology is applied to carry out optimum design on the dead weight, rigidity and intensity of the elevating mechanism under the condition of meeting the requirements of elevating height and carriage height. The specimen is tested, and the test result is used to validate the correctness of the design. This paper provides reliable basis for the pre- and post-treatment of the subsequent finite element analysis.
