According to the modern design concept and method of vitural prototype, Runshare design and research team discusses the method of physical prototype modeling and vitural prototype simulation and analysis of the operating mechanism referring to the GTBZ22Z aerial work platform. Based on the theory of mechanics and dynamic, use APDL language of hte finite element analysis software ANSYS to establish simple work platform model.It does static analysis of the telescopic arm in three extreme conditions. The results indicates that the maximum tensile stress over the section of the first arm link amplitude actuator, the crushing stress nether the section of the first arm link amplitude actuator. Bulking analysis shows that, when a load 7KN is applied to the platform, the section of the first arm around the amplitude actuator will appear bulking, the structure will not be stable.
From the result, the natural frequency and the GTBZ22Z working frequency is six to one which indicates that the system will not generate resonance.
Based on the theory analysis, the strength and model of Arm test was done in extreme conditions, the results of the test is similar to the results of finite element analysis. The conclusion confirm the accuracy of finite element model.
Based on the results of finite element analysis , aiming at decreasing the weight of telescopic arm, with the restriction of strength and rigidity of the telescopic arm, the optimization of three arms was carried out. The achievement of this research can provide valuable evidence for structures optimization of Runshare arms.
