The Finite Element Analysis of a Heavy Semi-trailer Frame Based on ANSYS Yao Ye, Yonghai WU Faculty of Traffic Engineering, Huaiyin Institute of Technology, Huai’an, China fengwang2022@163.com Keywords: Frame, FEM, ANSYS, Strength Abstract.
However, due to a large reduction simulated conditions, and not so much the actual deceleration of work, so the frame at full load emergency braking situation is still relatively high safety factor.

It is a hub of communications connected the northeast, north and northwest China; it is also the important international channels leading to Mongolia, Russia and eastern European countries.
In short, the choice of the small-scale cities’ new areas should consider its relations with the old areas, geographical location and traffic conditions.
Pingdiquan new area carries on Jining's city functions.Wulanchabu city is China's northern city transport hub, so its traffic has developed.
To establish a safety, comfortable, completely urban physical environment and to complete the community security system. 5.

The standards for passenger cars at low temperature were studied and proposed by combination of the technical content in cold regions’ environments and the development trend in the domestic and international situation.
In the industry standardization and the objective requirements of relevant standards, this proposed standards are the basis to ensure fair competition in international trade, maintain the normal order of market and make up a communication bridge among the international economic cooperations.
Engine cover lock, the trunk lock The trunk lock freeze to death, can't open; engine hood is normal Seat adjusting mechanism, seat headrest adjustment, seat after screen, pillow seats in armrest The front seat slippery course frozen, can't moved back and forth, other normal Safety belt Since the slow but gear clear, reliable.

Comparing to the traditional natural underground garage, the vertical garage as a new parking pattern has more outstanding advantages such as saving ground, more efficiently guarantee personal and car safety, easy management for in or out garage as well as flexible configuration[3], we can say that this kind of garage is indispensable choice for effectively improving city static traffic.
There is a queuing phenomenon with form and without form, for example, storage regulation of the reservoir, blocking and leading the vehicle and boats in the traffic centre of the train station and dock [5-6].

Proper numerical modeling of dynamic response of the bunds to impact, shock and traffic loading needs to be carried out.

The design of automotive interior fabric in our country is more focused on the design and research of comfort, safety, health and other functional aspects.
Automotive interior fabric design directly reflects the personality of the car and influence on comfort, environmental protection, safety, cost and other indicators of the car.
The design competition of international motordom has turned to interior design for a long time.
Color design should be helpful to reduce stress, relieve pressure and benefit to traffic safety.

UAVRS integrating GIS can bring up potential and secondary disaster points for guaranteeing safety of personnel and property.
In order to ensure the safety of the UAV and the accuracy of remote sensing image, the pattern elevation is set to 2200 m.
The disaster area is located in the remote mountainous areas, traffic is inconvenient, social and economic development is slow, and the disaster area terrain and status map does not update [17].
Hazard assessment Exclude potential and secondary hazard for safety relief.
