In the current vehicle development process, how to integrate vehicle dynamics systems (suspension, braking and steering systems) (as shown in Figure 1) into a unified chassis overall optimization design platform; how to develop global team resources, Forming an open, shared, and mutually beneficial R&D architecture is a technical challenge that every auto company must face.
For vehicle dynamics simulation, AMESim offers a comprehensive solution, a dedicated vehicle dynamics application library, written using optimized C code generated by MAPLE. It can realize the design of various parts of the chassis system (suspension, braking, steering and anti-rolling system), complete the integration of various parts of the chassis, establish the overall optimization design platform of the chassis, and design and develop the overall control of the chassis system. Strategy. Thereby greatly improving the user's research and development efficiency and shortening the development time of new products.
Suspension system solution
AMESim can perform spring, damper and other suspension component models to analyze the dynamics of the entire suspension system.
The AMESim suspension/anti-rolling solution can help users complete the design of each component structure in the system, build models of various components and the entire system, and analyze the influence of the structure, size and system structure of each component on the dynamic characteristics of the whole system. To help users understand the characteristics of each component from a holistic perspective. Various forms of suspension systems can be analyzed in AMESim, including passive, semi-active and active suspensions; suspensions for mechanical, hydraulic, pneumatic and magnetorheological fluids. And can analyze the performance of the overall system and components in detail.
For example, it is appropriate to ensure the control of the semi-active suspension system in order to design and verify the internal force control system. You can use AMESim and Matlab/Simulink interfaces to combine the two for co-simulation, as shown in Figure 2.

Friction Welding Machine is used for welding of homogeneous metals or different metals, which are connected by the friction welding with heat. The two work pieces are rubbed together with mechanical rotary motion and axial pressure (friction pressure). Heat will be generated during that course and the working pieces will be then heated to plastic state. The rotary motion will then stop and the machine will place a greater pressure (forge force) on the pieces at a certain duration. As result, the contact surface of work pieces will be connected.
Due to its advanced technology, stable quality and reliable performance, friction welding machine is widely used in aerospace, electric power, bearing, automobile, motorcycle, metal cutting tool, textile machinery, petroleum geological drilling, construction and other high-tech and traditional industries.
