摘要： A handheld quality inspection tool for projection welded components and method for utilizing the same is disclosed. The handheld quality inspection tool includes an elongated hollow tube, a spring support, a spring member, a plunger, and a handle. The elongated hollow tube defines a slot. The spring support is connected to an end portion of the elongated tube. The spring member is disposed within the elongated hollow tube and connected to the spring support. The plunger is disposed in the elongated hollow tube and connected to the spring member opposite the spring support. The handle is connected to the plunger and protrudes from the elongated hollow tube through the slot and is translatable along the slot to move the plunger and compress the spring member. Upon release of the handle, the compressed spring member propels the plunger to apply an impact force to a projection welded component.

摘要： Disclosed is a system and method for determination of the viscoelastic properties of a viscoelastic substance based on the type of non-mechanical forces which drive the viscoelastic substance inside a channel. These forces may comprise capillary, gravitational, electric, magnetic, or any other type where neither a pump nor any relative velocity between solid surfaces is needed to induce the transport of fluid medium. As a result, the design of the system remains simple, and the system is capable of yielding results devoid of noise produced by mechanical forcing. The present disclosure a general analysis describing extraction of viscoelastic properties by observing flow-systems driven by any non-mechanical means, including capillary force and electro-osmotic force. Such time-dependent penetration depth may be recorded by optical, electrical or mechanical means and may further include the use of a computing device.

摘要： A drop tower apparatus and method of use is provided. The drop tower apparatus includes a base, a frame, a top member, rails, a sled, a triggering system, and a test fixture. The frame extends from the base. The top member is disposed on the frame opposite the base and has a winch. The rails extend from the base to the top member and are disposed within the frame. The sled is configured to slide vertically along the length of the rails and is releasably connected to the winch of the top member. The test fixture is configured to receive a sample for testing. The winch of the top member raises the sled to a desired height, the sled is released at the desired height and slides along the rails resulting in an impact on a sample placed in the test fixture.
