Abstract: An active compensation algorithm for an inertia force of on-board equipment and a damping device are provided. The algorithm includes the following steps: a compensation angle acquisition step: acquiring an expected real-time inertia force compensation angle of a damped target when a vehicle takes a sudden turn or emergency braking based on velocity information, acceleration information, and angular velocity information of a vehicle chassis; and a control step: adjusting an angle of a damping motor by adopting a control algorithm according to the real-time inertia force compensation angle, where the damping motor keeps pace with the expected inertia force compensation angle in real time. The active compensation algorithm for the inertia force of on-board equipment can calculate the inertia force compensation angle of the vehicle in real time, so as to achieve a better inertia force compensation function to the damped target through the damping motor.

Abstract: Provided are a nano-titanium dioxide (NT)/biochar (BC) composite, and a preparation method and use thereof, which belong to the technical field of cement-based materials. NT is introduced into a porous structure of the micron-sized BC, which not only addresses the high aggregation of NT, but also reduces Ca(OH)2 size and crystal growth orientation through effects such as filling and nucleation brought by NT in the porous structure of BC. In this way, more C—S—H gels are generated to fill the pores, thereby improving an interfacial transition zone (ITZ), which enhances the mechanical properties such as compressive strength and flexural strength.
