J mole is the use of equipment selection method in the wheel cylinder and the vehicle pull up the role of friction relative movement through the simulated car driving on the road,<a href="http://www.toryburchsaler.net" target="_blank" class="postlink">tory burch shoes</a>, see Figure l, Figure 2. L lap 2 lap main drum design selection device perimeter is lm, the wife of the circumference of drum rotation is equivalent to the product of car driving away. Therefore, the accuracy of the circumference of the main drum a direct impact on the verification device to the total uncertainty. Usually installed in the bracket on the main drum diameter measuring the circumference of the existence of certain difficulties, the amount of the clamor direct http on both sides of the main drum support affected by the number of measurement tools difficult to use, if the measurement of the main drum removed. There is demolition, installation and assembly to ensure concentricity and other issues. Direct measurement by steel tape method of indole rough week should not be used. I can guarantee to find a thick measurement accuracy, but also simple and feasible strings Longbow Supreme Court. Second, the use of bow string measure the main drum Leopard Supreme Court steps l-measure chord length b.

If the caliper of the main ruler and measured the vertical cylinder of less than 2. , The tilt error can be caused by ≤ 0.15ram. Figure 32. Elimination of ovality cylinder measuring chord length b, in order to re-roll each 0.
