The dynamic behavior of the standard forklift according to the various working modes must be analyzed. Especially, the vibration of the mast end must be analyzed as such vibration is the main cause of the dynamic load generated in the cylinders and the linkage parts during the lifting operation. In this study, virtual test simulation was done for the lifting operation mode, and the results were validated. The full range of dynamic models was considered in SIMCENTER 3D Motion, and the hydraulic circuit of the cylinders was modeled in AMESIM. A vehicle test was also performed, and the local z-acceleration and pitch degree in the inner mast, the hydraulic pressure in the main control valve, and the carriage displacement were measured for comparison with the simulation results. All the experiments on the two cases were performed using pneumatic and solid tires. In the case of the mast dynamic behavior, the data obtained from the two main axes of the IMU(inertial measurement unit) sensor were compared using FFT(fast Fourier transform) analysis. In the 1st and 2nd modes, the analysis error rate was up to approximately 7 %. As shown by these results, the hydraulic and dynamic behaviors dependent on the tire can be evaluated using the presented co-simulation analysis method.
