Modification of the ball-joint for nissan pick up car

الملخص EN

A Nissan pickup car shown in Fig.1 is widely used car in Iraq.

In spite of its being sturdy, this car has a problem regarding to failure of their suspending ball joints.

Nowadays, it is seen the ball joint of this car fails suddenly without any sign of consumption and this case is a dangerous as well as disturbing factor for traffic and driver.

So there should be something else supports car when the ball-joint fails.

This research has a modification of this ball joint for this purpose.

The modification has depended on the results obtained from the numerical analysis of the loaded ball-joint in two situations (forms), the first situation (form) when its angle is negligible and second situation (form) when this angle is considerable.

Measurements of parts of ball joint of Nissan pickup car have been made and these parts have been drawn in two forms (situations) by using CATIA software.

Also, Measurements of parts’ lengths of suspension system of Nissan pickup car has been made and an approach model of its suspension system has been created by using MSC ADAMS software to view the angle of ball-joint with Max.travel of suspension system., all drawn forms have been imported to ANSYS WORKBENCH software where a three- dimensional model was created and maximum load is applied to ball-joint Then, solution had been done and the results were obtained.

Then, a modification is created and drawn by CATIA software, after that it is imported to ANSYS WORKBENCH software to check it ability for supporting the results.
