The need existed as testing with drivers was found to cause ergo concerns and was not repeatable. Again, trucks were instrumented and data was collected during real operations. A simulator was developed and put into use to benchmark normal handling, but also to understand what happens at extreme conditions. Use includes, loading against a container wall, trailer wall, getting output of forces both hammer and nail, adjustment of the tilt angle, raising the mast, and multiple product interactions. Case Study 3: Dolly Simulation Another example of a needed test that didn't exist is off-the-shelf is stair handling. Testing utilizing humans is not repeatable or ergonomic friendly, since appliances are heavy and difficult to balance. It's critical that when testing, the impact from stair 1 is equivalent to stair 17. Dollies were instrumented and several scenarios were evaluated including the angle of the dolly, height of stair, number of stairs, effect of wheels, and location of data logging device. In this case, an existing piece of equipment (a shock table) was fixtured to allow for a modified dolly to be mounted. Once the appliance is placed on the dolly, a clamp truck can be used to place the unit and dolly onto the shock table where it is secured tested. Results include repeatability and elimination of the ergo concern. Conclusion: How do you know a new packaging design is better and more robust than existing? The answer lies in reproducing events found in your specific environment. Off-the-shelf equipment/standards may not be specifically tailored to your distribution environment. Once reliable, repeatable testing can occur, the use of finite element analysis can be enhanced to further predict and reduce testing time.
