The interconnected hydropneumatic suspension (ICHPS) has not only the nonlinear stiffness and damping of the independent hydropneumatic suspension (IDHPS) but also antiroll and antipitch functions.The existing analysis of hydropneumatic suspension damping mainly focuses on the orifice and check valve in the suspension cylinder.In this study, the calculation formula of the damping force Daily natural gas load prediction method based on APSO optimization and Attention-BiLSTM of ICHPS is established, and the numerical simulation results show that the damping characteristics of the hydraulic hose cannot be ignored.
The influence of check valve and hose on the damping characteristics is analyzed.Through the equivalent energy method, the equivalent compression damping ratio and the equivalent recovery damping Fractional differencing in stock market price and online presence of global tourist corporations ratio of the ICHPS are established.It is pointed out that when designing the damping characteristics of the ICHPS, it is necessary to select the orifices, check valves, and hose damping reasonably to make the damping characteristics get the best match.
