In present time, the character of industry is time reduction. As our society change rapidly, industry should change rapidly. Automobile industry change so much for past 100 years. Nowadays car is used only for transportation also life. At this time, many automobile companies keep at reduction of development period. In past time, we validate vehicle on the road. But, in present time, we don't have enough time to validate vehicle on road due to the taste of customer rapidly changed. It is a reason for many automobile companies to do their best at RLM (Road to Lab to Math) project Laboratory working takes place of the things to be done in the real road. Therefore, in this paper, the method to improve laboratorial simulation test is suggested by data editing and some technique.

In present time, all industries are rapidly changed by customer needs and do their best to adapt the customer. The key of automotive industry is also the reduction of the development period to adapt to the speedy change of customer needs. To do this, many automotive companies do their best at RLM (Road to Lab to Math). It results in extend the role of CAE (Computer Aided Engineering) and CAT (Computer Aided Testing). CAT work is focused on rapid test result and good correlation with real test. It is important to choose the test method for test period and test quality. Therefore, in this paper, the method to validate the vehicle durability performance is suggested using 4post road simulator.

These days, the road simulators in the laboratory have become a common tool within the automotive industry for evaluation and validation of vehicle durability performance. Also, all industries are rapidly changed according to the customer needs and try to do their best to apply the customer needs. So, the key of automotive industry is the reduction of the development period to adapt to the speedy change of their needs. These works are focused on rapid test results and good correlation with actual test. In this paper, using the local strain, the test drivefile was regenerated for the full vehicle road simulator and compared the RLDA, target signal. The proper local strain is necessory to generate the drivefile on full vehicle simulation test.

These works are focused on rapid test results and good correlation with actual test. In this paper, RLD are correlated with the CAE vehicle model, regenerated by the full vehicle road simulator and correlated the pseudo damage between desired file and rig reponse file.

This test improvement is applied virtual Road Load Data correlated with physical PG sensor data at 8ch. test rig which is called suspension multi axial test. Up to now, there is no measuring method of acquiring the specific points of rear axle trailing arm area. Because of a constraint condition of CAE modeling, it is impossible to use the local specific points of individual component parts around rear axle. It is more important to be regenerated on individual component strain than 6 degree of freedom on rear wheel force center from a durability point view. Especially, it is more difficult to simulate suspension 8ch. test which is applied torsion beam type rear axle. In this paper, we focused to increase the reliability of 8ch. test according to the correlation between virtual and physical model and RLD about local stress in particular components. A physical RLD Sensor of rear are correlated with the CAE vehicle model at rear axle trailing arm about longitudinal and lateral direction between actual PG data and virtual PG data. Finally, test drive file are regenerated by the half car road simulator test with vRLDA which is correlated with actual sensor model.

These days, chassis part validation has saved time and expenses by executing bench test in the lab instead of full vehicle road test. However, it shows difficulties to demonstrate all vehicle parts motion in the full vehicle simulation test due to test boundary condition. Especially, steering gear system is hard to be reproduced in the full vehicle simulation test because it is difficult to turn the steering wheel. To compensate these problems, several kinds of steering system tests are running in the lab, apart from full vehicle tests. This study is to address a method to validate steering gear, cradle, structure and attachment system laboratory durability test.

Chassis parts of vehicle has been tried to be validated through a bench test in lab. Instead of a full vehicle test on road that a lot of time and costs are required of. In case of a bench test in lab., it is very important to correlate with full vehicle test result on road. Actually, reliability of a test depends on the correlation. Therefore, many engineers are making an efforts to have good correlation. Generally a simulation test is regarded as the most reliable test method. In this sense, durability of chassis system could be evaluated with 8ch Multi Axial Simulation Rig. 8ch test is the highest level test in lab. to evaluate torsion beam rear axle durability and it is capable to simulate 8-DOF. The study of purpose is to improve correlation of results between road and 8ch lab test for torsion beam rear axle using local strain on the part. It is also to improve correlation on lab test.
