According to the modern design idea and method of vitural prototype, the Runshare design and research team describes the process of physical prototype modeling, vitural prototype simulation, and operating mechanism analysis using the GTBZ21 aerial work platform. Based on mechanics and dynamic theory, create a simple work platform model using the APDL language of the finite element analysis software ANSYS.

It performs static analysis on the telescopic arm under three extreme circumstances. The results show that the maximum tensile stress is beyond the section of the first arm link amplitude actuator, while the crushing stress is below the section of the same. Bulking study reveals that when a load of 7KN is applied to the platform, the section of the first arm around the amplitude actuator seems bulky, and the structure is unstable.

The result shows that the natural frequency and the GTBZ21 operating frequency are six to one, indicating that the system will not cause resonance.
Based on the theory analysis, the strength and model of Arm test was performed in extreme conditions, and the test results were identical to those of finite element analysis. The finding confirms the accuracy of the finite element model.

The ratio of natural frequency to GTBZ21 operating frequency is six to one, indicating no resonance in the system.

The Arm test was conducted in harsh conditions based on theoretical analysis, yielding results similar to those of finite element analysis. The finding confirms the accuracy of the finite element model.
