Abstract To study the dynamic response of a certain type of co-frame launcher during launch, this article uses the 3D modeling software Pro/E to import the model into Adams from the perspective of launch dynamics. the launch dynamics model of the shared-frame launcher is established. We apply the ejection thrust of the two types of missiles to the corresponding ejection devices and measure and collect the dynamic parameters of the cartridge system. The simulation results show that the dynamic parameters of the A and B missiles are in line with the available overload design requirements. The B-type missiles are superior to the A-type missiles in terms of ballistic orbit contact force and ejection attitude.

With the rapid development of the world economic construction and the shortage of energy, it has become a hot research issue to realize the electrification of the vehicle driving system and improve energy efficiency. Most of the electric construction machinery power systems are characterized by low speed and high load. The coordinated driving of multiple motors can increase the output torque and improve the transmission efficiency of the machine on the basis of a compact layout. A novel configuration of electric construction vehicles based on multi-motor and single-speed and its driving torque distribution control method is presented in this paper. The detailed mathematical model is established and the simulation analysis is carried out based on it. The results show that the proposed multi-motor driving system with the control strategy can improve the overall efficiency in the condition of ensuring the driving force when the parameter matching and motors choosing reasonably.

Design Requirements

Unlike commercial sliding rails, space sliding rails need to meet complex mechanical requirements in the state of ground tooling, launch and on-orbit. The former could slide smoothly while their carrying capacity is low. As a result, they cannot be applied directly to the space stations, manned spacecrafts and other space probes. Hence, it is necessary to design a kind of full-pulling sliding rails which can be suitable for three completely different mechanical conditions. In this paper, we firstly built the mechanical models of the ground tooling, launch and on-orbit state, then a kind of sliding rails is designed according to the mechanical models, finally, a simulation analysis was carried out on the designed sliding rail. The result shows that this kind of sliding rails meets all the design requirements, which verifies the validity of the models.
