The stiffness parameters of cabin suspension have an important effect on the comfort of fork lift trucks. Analysis of the cabin system of fork lift trucks often requires the retrieval of the stiffness parameters of cabin suspension systems. Convenient methods of retrieving stiffness parameters without dismantling the cabin suspension system cannot be obtained unless a special bench test is conducted. This process is inconvenient for researchers and technicians. A cabin model with three degrees of freedom was constructed, including a simulation model, to provide a convenient method for retrieving stiffness parameters. A model for the identification of stiffness parameters was established on the basis of the test data and the simulation model. The stiffness parameters were identified through a case study and the values retrieved coincide with the test results. The results show that the method built is reliable and provides an effective way of retrieving the stiffness parameters of cabin suspension for fork lift trucks.
